What is General Nuclear Medicine?

Nuclear medicine is a specialty within the field of diagnostic imaging. It comprises diagnostic examinations that result in images of body anatomy and function. The images are developed based on the detection of energy emitted from a radioactive substance given to the patient, either intravenously or by mouth. Generally, radiation to the patient is similar to that resulting from standard x-ray examinations.

What are some common uses of the procedure?

Nuclear medicine images can assist the physician in diagnosing diseases. Tumors, infection and other disorders can be detected by evaluating organ function. Specifically, nuclear medicine can be used to:

  • Analyze kidney function
  • Image blood flow and function of the heart
  • Scan lungs for respiratory and blood-flow problems
  • Assess disease in the digestive system
  • Evaluate bones for fracture, infection, arthritis or tumor
  • Determine the presence or spread of cancer
  • Identify bleeding into the bowel
  • Locate the presence of infection
  • Measure thyroid function to detect an overactive or underactive thyroid
