Regardless of the condition being treated or the surgical division involved, medical imaging is a powerful tool that guides diagnosis, treatment planning, and patient outcomes. This is particularly true in surgical oncology.

In cancer treatment, medical imaging has revolutionized how surgical oncologists approach cancer care. Sophisticated cancer imaging with surgical oncology is much more advanced and precise compared to the exploratory approaches of the past.

Today’s surgical oncologists can use advanced medical imaging to guide every decision, from cancer diagnosis and treatment planning to the surgical oncology procedure itself, as well as follow-up care and monitoring.

CT scans, MRIs, and PET scans provide more accurate cancer diagnosis and give surgeons a clear and accurate view of the tumor and the surrounding structures before ever making an incision.

Then, during surgery, advanced cancer imaging techniques add real-time precision, leading to more accurate diagnoses, better tumor removal, preservation of healthy tissue, fewer complications, and improved long-term outcomes.

The Surgical Clinic in Middle Tennessee uses the most advanced imaging technologies available to develop individualized cancer care plans. Our approach recognizes that no two cancers are identical, and the detailed information provided by modern imaging ensures that each patient’s treatment strategy is tailored to their specific situation.

In this blog, we’ll explain what imaging tests are, the different types available, how each is used in cancer treatment, and what it means for every step of your cancer diagnosis and care.

The Essential Role of Medical Imaging in Cancer Care

If you or a loved one is facing a cancer diagnosis or preparing for cancer surgery, understanding how imaging guides your surgery team through every stage of the diagnostic and treatment process can provide a little more peace of mind, confidence in your care plan, and realistic expectations for recovery.

What Are Imaging Tests?

Imaging tests are medical procedures that create visual representations of the inside of the body to help doctors detect, diagnose, and monitor disease.

Medical imaging in the context of cancer care creates detailed pictures of internal body structures that allow cancer doctors to see inside the human body without making a single incision.

These technologies are non-invasive, generally painless, and provide crucial visual information that guides everything from initial cancer diagnosis and surgical planning to real-time intraoperative navigation and postoperative monitoring to better ensure the effectiveness of treatment.

Cancer imaging tests use different types of energy, such as X-rays, sound waves, magnetic fields, or radioactive substances, to highlight cancerous cells and tumors, helping doctors to determine the extent of the disease and plan the best course of action.

Types of Imaging Tests in Cancer Treatment

Where surgeons once had to rely on physical examination and basic X-rays, today’s surgical oncologists have access to much more advanced imaging technologies that can reveal tumors smaller than a grape, distinguish between different types of tissue, and even show how actively cancer cells are growing. 

These tests are crucial tools used before and sometimes after surgery to detect, stage, or monitor cancer. Surgical oncologists can also use imaging during surgery through intraoperative techniques to provide real-time visualization and help ensure complete tumor removal while protecting surrounding healthy tissue.

The different types of modern imaging tests used in cancer treatment include:

CT Scans: The Detailed Roadmap

CT (Computed Tomography) scans create detailed cross-sectional images of the body by taking multiple X-ray images from different angles and combining them using computer processing into comprehensive pictures. Think of it as creating a detailed roadmap of your internal anatomy.

For surgical oncology, CT scans provide several crucial pieces of information:

  • Tumor location and size: CT scans reveal the precise location and size of tumors, showing exactly where cancer is located in relation to surrounding organs, blood vessels, and other structures. This level of detail helps surgeons map out the safest and most effective approach for tumor removal while protecting healthy tissue.
  • Detection of metastases: CT scans excel at detecting if cancer has spread from its original location to other parts of the body. This information is crucial for staging cancer and determining whether surgery is the best treatment option. For example, if a lung cancer patient’s CT scan reveals multiple tumors in both lungs, the surgical approach would be very different than if the scan showed a single, isolated tumor.

CT scans are simple. The imaging typically takes only 10-30 minutes, during which you lie on a table that slides through a large, donut-shaped machine. The scan itself is painless, though you may receive contrast material through an IV to help certain structures show up more clearly on the images.

MRI: Superior Soft Tissue Visualization

MRI (Magnetic Resonance Imaging) technology uses powerful magnetic fields and radio waves to create detailed images of internal structures. Unlike CT scans, which excel at showing bone and detecting calcifications, which can be very helpful for identifying fractures or certain types of tumors, MRI provides superior contrast between different types of soft tissue.

This superior soft tissue visualization makes MRI particularly valuable in cancer imaging for specific types of tumors:

  • Brain tumors are best evaluated with MRI because it can distinguish between tumor tissue and normal brain tissue with remarkable precision. 
  • Breast cancer evaluation often includes an MRI to determine the extent of disease and identify additional areas of concern that might not be visible on mammography.
  • For liver and pancreatic cancers, MRI provides detailed information about tumor location relative to blood vessels and bile ducts, information that’s crucial for surgical planning. 
  • Spinal tumors often require MRI evaluation to understand their relationship to the spinal cord and nerve roots.

One significant advantage of MRI in cancer treatment is its safety profile. Unlike CT scans, MRI doesn’t use ionizing radiation, making it safer for patients who require multiple imaging studies over time.

The MRI machine can be a little noisy, but other than that, an MRI is painless and quick. It requires a little more time than CT scanning, but still only lasts about 30 to 60 minutes.

PET Scans: Detecting Cancer Activity

PET (Positron Emission Tomography) scans represent a fundamentally different approach to medical imaging. Rather than simply showing anatomical structures, PET scans reveal metabolic activity, which is how actively cells are consuming glucose.

Since cancer cells typically consume glucose at much higher rates than normal cells, PET scans can detect cancer based on this increased metabolic activity.

This unique capability makes PET scans invaluable for surgical oncology in several ways:

  • Differentiating scar tissue from active cancer: PET scans can distinguish between scar tissue from previous treatments and active cancer, a distinction that’s often impossible to make with CT or MRI alone. This is particularly important for patients who’ve had previous cancer treatments and develop new areas of concern on follow-up imaging.
  • Finding hidden metastases: PET scans also excel at detecting small metastases that other imaging methods might miss. They’re particularly useful for staging cancers like lung cancer, lymphoma, and melanoma, where detecting the full extent of disease is crucial for treatment planning.


Providing combined insights: Often, PET scans are combined with other medical imaging, such as CT scans. The combination of PET with CT, known as PET-CT scans, provides both metabolic and anatomical information in a single study. This combination provides surgical oncologists with the most comprehensive view possible of a patient’s cancer, revealing not only the location of abnormal tissue but also its metabolic activity.

PET scans involve receiving a small amount of radioactive glucose through an IV. This tracer is very safe, uses only a low dose of radiation, and naturally leaves the body within a short time.

After the injection, patients typically wait about an hour before the actual scanning begins. The scan itself takes 30–45 minutes and is painless.

Image-Guided Surgery Systems: Real-Time Navigation for Cancer Surgery

Image-guided surgery systems combine pre-op imaging with real-time navigation, giving surgeons GPS-like guidance during procedures. These systems are used in a wide variety of cancer surgeries, but are particularly valuable for brain surgery and other procedures where millimeter-level precision is crucial.

Two of the most common cancer image-guided techniques are fluorescence imaging and intraoperative ultrasound. 

Fluorescence Imaging: Making Cancer Cells Visible During Surgery
Fluorescence imaging is an advanced imaging technique used during cancer surgery. It allows surgeons to see cancer cells that have been tagged with special dyes, helping ensure complete tumor removal.

When exposed to special lighting in the operating room, these dyes cause cancer cells to glow, making them easier to distinguish from surrounding healthy tissue. This real-time visualization enhances accuracy, enabling surgeons to preserve as much healthy tissue as possible.

Intraoperative Ultrasound: Real-Time Imaging for Safer Tumor Removal

This isn’t your average ultrasound. Intraoperative ultrasound is performed during surgery to give surgeons live, detailed images of the area they are operating on.

Intraoperative ultrasound allows oncology surgeons to precisely locate tumors, evaluate their relationship to blood vessels or other critical structures, and confirm successful tumor removal before finishing the procedure. This real-time guidance is especially valuable in surgeries involving the liver, pancreas, and brain.

How Imaging Tests Are Used in Cancer Treatment

The integration of imaging in cancer treatment plays a role at every stage of care.  Each step builds upon the one before it, creating a comprehensive picture that enables surgeons to make informed decisions and patients to feel more secure in their treatment journey.

Whether you are about to undergo breast cancer surgery, have a procedure for thyroid cancer planned, are in the early stages of stomach cancer, pancreatic cancer, or any other type of cancer that involves surgical oncology, understanding this process can help patients and loved ones of those diagnosed with cancer feel more confident about treatment and more engaged in their care decisions.

Here’s how imaging is used at each stage of cancer surgery:

1: Diagnosis and Staging: Defining the Extent of Cancer With Imaging

If cancer is suspected, the first medical imaging tests confirm the presence of cancer and determine its extent.

This process typically involves multiple imaging studies, each providing valuable information that helps doctors see the full picture of the disease and decide on the most effective next steps in treatment.

For example, a patient with lung cancer might undergo a chest CT to evaluate the primary tumor, a PET-CT to look for metastases, and a brain MRI to check for brain involvement.

The staging process uses a standardized system (typically the TNM system) that describes:

  • T (Tumor): The size of the primary tumor and whether it has grown into nearby tissues.
  • N (Nodes): Whether cancer has spread to nearby lymph nodes.
  • M (Metastasis): Whether cancer has spread to other parts of the body.

This staging information, derived mainly from imaging studies, determines not just whether surgery is appropriate but also what type of surgery offers the best chance for success.

2: Pre-Surgical Planning: Building the Surgical Strategy

Once a proper diagnosis is made and staging is complete, surgical roadmapping begins. This is where the art and science of surgical oncology come together.

Using detailed imaging studies, surgeons create three-dimensional mental maps of the surgical field. They identify the tumor’s exact location, its relationship to critical structures like blood vessels and nerves, and the optimal surgical approach.

Modern imaging software can create 3D reconstructions of tumors and surrounding anatomy, allowing surgeons to practice procedures virtually before entering the operating room. This level of preparation was almost unimaginable a few decades ago, but has now become standard practice for many complex cancer surgeries.

The decision between minimally invasive and open surgical approaches often depends on these imaging findings. If imaging shows that a tumor is small and well-separated from critical structures, a minimally invasive approach might be possible. However, if imaging reveals extensive disease or involvement of major blood vessels, an open approach might be necessary.

At The Surgical Clinic’s surgical oncology division, this planning process is essential to our individualized approach to cancer care. No two patients receive identical treatment plans because no two cancers are identical. The detailed information provided by modern imaging ensures that each patient’s treatment plan is tailored to their specific situation.

3: During Surgery: Real-Time Guidance

The role of imaging in cancer treatment doesn’t end when surgery begins. In many cases, it becomes even more important in the operating room.

Intraoperative imaging provides real-time guidance during surgery, helping surgeons navigate complex anatomy and ensure complete tumor removal. These navigation systems provide GPS-like guidance during surgery.

They use pre-operative imaging to create detailed maps of the surgical field, then track surgical instruments in real time, showing surgeons exactly where they are in relation to critical structures.

There are several approaches to intraoperative imaging, but two of the most advanced and widely used are intraoperative ultrasound and fluorescence-guided imaging.

  • Intraoperative ultrasound is a specialized ultrasound performed during surgery to provide live, detailed images of internal organs and tissues. This technology allows surgeons to locate tumors precisely and determine their relationship to major blood vessels, information that’s crucial for safe tumor removal. It is particularly valuable in instances where it can identify tumors that aren’t visible or palpable from the surface. 
  • Fluorescence-guided surgery is another tool and represents one of the most exciting advances in surgical oncology. In this technique, patients receive special dyes that are taken up preferentially by cancer cells. During surgery, these dyes fluoresce under special lighting, essentially making cancer cells glow. This allows surgeons to see cancer tissue that might otherwise be indistinguishable from normal tissue.

When combined with modern surgical methods, such as robotic surgery, these advanced imaging systems take surgical precision to new levels. Robotic systems can incorporate real-time imaging data, providing surgeons with enhanced visualization and unprecedented control during complex procedures. This combination of advanced imaging and robotic technology now makes possible procedures that would have been out of reach just a few years ago.

4: Post-Surgical Assessment: Ensuring Success

The role of imaging often continues after surgery is complete. Immediate post-operative imaging helps surgeons confirm that they’ve achieved their surgical goals. For cancer surgery, this often means confirming complete tumor removal and checking for any immediate complications.

Post-op imaging can provide immediate peace of mind for both patients and surgeons. When imaging confirms complete tumor removal with clear margins, it validates the surgical approach and provides confidence about the procedure’s success.

Long-term surveillance imaging is also typically part of ongoing cancer care. The ultimate goal with post-op imaging is to detect potential recurrence as early as possible, when treatment is most likely to be successful. 

Different types of cancer require different follow-up imaging schedules. The frequency and type of surveillance imaging depend on many factors, including the type and stage of the original cancer, the completeness of surgical removal, and the patient’s overall health.

For example, a patient who has had colorectal cancer surgery may undergo regular CT scans and blood tests to monitor for recurrence. Whereas a patient with breast cancer may have follow-up mammograms or breast MRIs every 6 to 12 months to check for any new changes or signs of recurrence.

At The Surgical Clinic, we work with each patient to develop surveillance plans that provide appropriate monitoring while minimizing unnecessary testing. This long-term relationship between patients and their surgical oncology team reflects our commitment to comprehensive cancer care. We don’t just perform surgery and send patients on their way. We remain partners in their ongoing health and recovery.

The Life-Changing Benefits of Imaging-Guided Surgical Oncology

The integration of advanced medical imaging with surgical oncology has not only transformed the way surgeons plan and perform cancer surgery, it has also modernized cancer care in ways that directly benefit patients and make measurable differences in both outcomes and quality of life.

Enhanced Surgical Precision

Modern imaging in cancer treatment enables surgical precision that was previously unimaginable. Surgeons can now plan procedures with millimeter-level accuracy, removing tumors while preserving healthy tissue and organ function to a far greater degree than was previously possible.

This translates into better outcomes for patients in numerous ways. For example, breast-conserving surgery relies heavily on imaging to determine whether complete tumor removal is possible while preserving breast appearance. Advanced imaging techniques can identify the exact extent of cancer, allowing surgeons to remove all diseased tissue while preserving as much healthy breast tissue as possible.

Nerve-sparing prostate surgery is another example of how imaging-guided precision improves patient outcomes. Detailed MRI imaging can show the relationship between prostate tumors and the delicate nerve bundles responsible for urinary and sexual function. This information allows surgeons to remove cancer completely while preserving these critical functions whenever possible.

In liver resection procedures, the importance of imaging centers around preserving organ function. The liver has a complex internal anatomy with multiple segments, each with its own blood supply. Advanced imaging allows surgeons to plan resections that remove cancer while preserving maximum liver function, which is crucial for patient recovery and long-term health.

Improved Safety and Reduced Complications

Comprehensive pre-operative imaging significantly reduces surgical risks by allowing surgeons to anticipate and prepare for potential complications. When surgeons know exactly what they’ll encounter during surgery, they can plan accordingly, reducing operative time and minimizing the risk of unexpected issues.

Better pre-operative planning also leads to shorter operative times, which correlates with reduced complication rates. Patients who undergo shorter procedures typically experience less blood loss, lower infection risk, and faster recovery times.

Additionally, the ability to identify critical structures before surgery helps surgeons avoid inadvertent injury to important organs, blood vessels, or nerves. This is particularly important in cancer surgery, where tumors can distort normal anatomy and make it more challenging to identify these structures.

Studies consistently show that patients who undergo imaging-guided cancer surgery experience lower complication rates, shorter hospital stays, and a quicker return to normal activities compared to historical controls.

Better Long-Term Outcomes

The level of precision that imaging in cancer treatment provides translates into improved long-term outcomes, including survival rates. When surgeons can achieve complete tumor removal with clear margins, patients have the best possible chance for a cure.

Reduced recurrence rates are another significant benefit. When imaging guides complete tumor removal, the likelihood of local recurrence decreases substantially. This is particularly important for cancers where recurrence can be difficult to treat effectively.

Imaging also supports faster recovery, which benefits patients in multiple ways. Shorter hospital stays lower the risk of hospital-acquired infections and other complications. A quicker return to normal activities not only improves quality of life but also reduces the psychological impact of cancer treatment.

Finally, the preservation of organ function made possible by imaging-guided surgery has profound implications for long-term well-being. Patients who maintain normal function of organs like the liver, kidneys, or reproductive organs experience better health outcomes and quality of life over time.

Patient Empowerment and Confidence

It’s not a perk that might come to mind over safety, recovery time, or better long-term outcomes. But perhaps one of the greatest benefits of modern imaging in cancer treatment is how it empowers patients and helps reduce anxiety about their care.

When patients and their loved ones can see detailed images of their cancer and understand exactly what their surgical team plans to do, they feel more confident in their treatment decisions and more hopeful about successful outcomes.

Visual aids created from imaging studies help patients understand their diagnosis and the treatment options available to them. This understanding gives patients confidence to speak up and take an active part in shared decision-making between patients and their surgical teams, leading to treatment plans that reflect patient values and preferences.

The detailed information provided by imaging also helps set realistic expectations about surgery and recovery. When patients know what to expect, they are better prepared for their surgical experience and more likely to follow post-operative instructions.

Final Thoughts: The Power of Imaging in Cancer Treatment

The integration of advanced medical imaging in cancer treatment has completely changed what’s possible in surgical oncology, and as technology continues to advance, it will remain at the center of modern cancer care.

From the first diagnostic scan to the real-time guidance used in the operating room, advanced imaging gives surgeons the precision they need to remove cancer safely while preserving as much healthy tissue as possible. For patients, this means more accurate diagnoses, safer surgeries, faster recovery times, and better long-term outcomes.
