Nuclear Medicine

Nuclear medicine is a subspecialty within the field of radiology. 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.

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
  • Identify blockage of the gallbladder
  • 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

PET CT

There are tremendous advantages of having a combined PET CT:

  • Earlier diagnosis due to the high quality images
  • Chance of better outcome due to accurate staging and localization
  • Ability to detect recurrence in its early stages
