Imaging Services

Thanks to the latest and most advanced technology, our full-service Radiology Imaging Department creates superior images for diagnosing illness. We can electronically capture, store and transmit images of the body without film.

CT scans

Computed tomography (or CT) scans, sometimes called computerized axial tomography (CAT) scans, combine the power of X-rays and computers. Doctors can see a patient’s internal anatomy without surgery.

These scans reveal bone and soft tissues, including organs, muscles and tumors. CT greatly helps doctors with diagnosis, surgery and treatment. For example, in radiation therapy, determining the correct dose for a patient depends on knowing the precise density, size and location of a tumor.

At Fort Sanders Regional Medical Center, our **Lightspeed® 64-slice VCT scanner** is an example of the latest technology. It captures a precise image of the brain instantaneously, the heart in just five heartbeats, and the full body in 10 seconds, and can scan for stroke symptoms in less than a second. It can detect any of the three most dangerous causes of chest pain with a one fast scan instead of hours of tests.  The Lightspeed® 64-slice VCT scanner provides faster scans with lower-dose radiation resulting in quicker diagnosis and treatment for patients.

MRI scans

With our state-of-the-art MRI capabilities, we offer various types of body imaging. Because magnetic resonance imaging – or MRI – can give such clear pictures, it is the most sensitive exam for many problems.

For instance, an MRI often is used to diagnose sports injuries. Thanks to its precision, doctors can detect tears in tissue, tumors, swelling, and problems with joints and bones.

Our 3-Tesla MRI helps diagnose and treat problems involving the brain and spine. This system is twice as powerful as, and faster than the standard MRI machines typically used for patient care imaging. ((from University of Michigan Web site)) It is the latest advancement in magnetic resonance imaging, which gives doctors the best view of soft body tissue.


MRI pictures are amazingly clear and detailed. The technique- based on radiofrequency waves and a strong magnetic field – rather than X-rays – helps identify cancer, heart and vascular disease, stroke, joint and musculoskeletal problems and other disorders.

Because there’s no radiation exposure to the patient, MRI has become a popular diagnostic tool.

Nuclear medicine

Fort Sanders Regional Medical Center’s diagnostic imaging also includes nuclear medicine for heart, cancer and fracture scans.

This tool often spots abnormalities early in a disease’s progression. It also provides a way to gather information that otherwise would be unavailable or require surgery or more expensive diagnostic tests.

Nuclear medicine specialists use safe, painless techniques to get body images and treat disease. Patients ingest small amounts of radioactive materials (radiopharmaceuticals). Special cameras can pick up the images and send pictures to computers.

In treatment, the radiopharmaceuticals go directly to the organ being healed. This allows for great precision.

Nuclear medicine is used to:

  • Analyze kidney function
  • Provide images of blood flow and heart functioning
  • Scan lungs for respiratory and blood-flow problems
  • Identify gallbladder blockages
  • Evaluate bones for fractures, infection, arthritis or tumors
  • Determine the presence or spread of cancer
  • Identify bleeding in the bowel
  • Locate infections
  • Measure thyroid for overactive or underactive functioning.
  • Picture Archival & Communication System
  • This technology allows images to be electronically captured, stored and transmitted – all without film.

PET Services

Thompson PET Services, a department of Fort Sanders Regional, is located on the basement level of Thompson Cancer Survival Center – Downtown. The center is accredited in positron emission tomography by the American College of Radiology (ACR). This accreditation assures patients that their treatment meets the most rigid standards of excellence mandated by the ACR.


Picture Archival and Communication System (PACS)

PACS makes high-quality MRI, CT, X-ray and ultrasound pictures immediately available by computer. That means doctors can readily view any images the patient has had taken at Fort Sanders Regional Medical Center and other locations in the Covenant Health system.

Patients no longer need to carry X-rays from place to place. In addition, PACS gives such clear images that doctors believe it results in a better, more accurate diagnosis.


At Fort Sanders Regional Medical Center, doctors rely on ultrasound for images of the heart, abdomen, kidneys and other parts of the body.  Images are obtained through the use of high frequency sound waves.

New ultrasound units provide the latest in imaging capabilities. Doctors can see pictures of internal organs as they function and also can assess blood flow.

For instance, Vivid 7, the ultrasound for heart patients, can perform stress echo tests. Doctors rely on these to detect and diagnose conditions such as heart failure.

The benefits of ultrasound include no radiation exposure, comprehensive and reliable exam data, fast  tests and improved patient comfort. 


New, all digital equipment produces exceptional quality images in seconds.
