Taking Care of You from the Inside Out

Radioactive tracers inserted into the body and scanned give doctors a look at organ function. 

Nuclear Medicine is the area of Radiology that uses small amounts of low-level radioactive material to diagnose or treat diseases. These noninvasive and usually painless medical tests can help doctors diagnose many conditions, including cancers, injuries and infections. They can also show the structure and function of internal body parts, such as bones, kidney, bowel, gallbladder, thyroid, heart and others.

The type of test administered depends on each patient’s specific condition, but may include positron emission tomography (PET) scans, computed tomography (CT) scans, magnetic resonance imaging (MRI), heart scans or other advanced imaging technology. 

Nuclear Medicine testing is used to locate an infection, analyze organ function, examine blood flow, evaluate a stroke, detect the presence or spread of cancer, measure thyroid function, localize lymph nodes before surgery and scrutinize abnormalities in the brain. See below for other common uses.

With our advanced software technology and electronic medical records system, your physician has access to your image and all of your clinical information. Your images are read by a radiologist who provides your physician with a full report.

Kelsey-Seybold’s Nuclear Medicine team includes not only the first head of the Nuclear Medicine Department, David Mouton, M.D., who started with the clinic in 1972 when there was one tech and one scanning instrument, but also now includes several of the Radiology Department’s members with special interests in Nuclear Medicine. In addition, the team includes several Kelsey-Seybold cardiologists who are subspecialized in the performance and interpretation of cardiac studies.

Kelsey-Seybold has four locations (Berthelsen Main Campus, Spring Medical and Diagnostic Center, Tanglewood,​ and Fort Bend Medical and Diagnostic Center) where Nuclear tests are performed and a technical team of 40 certified technologists. This ensures that patients can be seen quickly at a convenient location. 
Patients can be assured their radiation exposure will be kept to the lowest levels possible while still providing accurate results. ​
Common Uses for Nuclear Medicine Imaging
Nuclear Medicine is used to:
  • Identify the presence of coronary artery disease and the amount of coronary stenosis (blockage)
  • Assess damage to the heart after a heart attack
  • Visualize heart blood flow and function
  • Weigh treatment options, such as heart bypass surgery and angioplasty
  • Scan lungs for respiratory and blood flow issues
  • Examine bones for fractures, infection and arthritis
  • Evaluate bone tumors
  • Detect the early onset of neurological disorders such as Alzheimer’s Disease
  • Check for abnormalities in the brain in patients with seizures, memory loss or possible irregularities in blood flow
  • Locate bleeding into the bowel
  • Identify inflammation or abnormal function of the gallbladder
  • Assess lymphedema
  • Gauge fever of unknown origin
  • Locate the presence of infection
  • Measure thyroid function to detect an overactive or underactive thyroid
  • Stage cancer by determining the presence or spread of cancer
  • Evaluate response to cancer therapy
  • Detect rare tumors of the pancreas and adrenal glands
  • Analyze kidney blood flow and function
  • Detect urinary tract obstruction
