Procedures are noninvasive medical test that help physicians diagnose a variety of medical conditions. Depending on the type of nuclear medicine exam you are undergoing, the radiotracer is either injected into a vein, swallowed or inhaled as a gas. It eventually accumulates in the organ or area of your body being examined, where it gives off energy in the form of gamma rays. The nuclear camera detects the gamma emission and produces an image. Nuclear medicine imaging scans are performed to:

  • Analyze kidney function
  • Visualize heart blood flow and function (such as a myocardial perfusion scan)
  • Scan lungs for respiratory and blood flow problems
  • Identify inflammation in the gallbladder
  • Evaluate bones for fractures, infection, arthritis and tumors
  • Determine the presence or spread of cancer in various parts of the body
  • Identify bleeding into the bowel
  • Locate the presence of infection
  • Measure thyroid function to detect an overactive or underactive thyroid
  • Investigate abnormalities in the brain, such as seizures, memory loss and abnormalities in blood flow
  •  Localize the lymph nodes before surgery in patients with breast cancer or melanoma
