Nuclear Medicine is a branch of medical imaging that uses small amounts
of radioactive material to diagnose or treat a variety of disease, including
many types of cancers, heart disease and certain other abnormalities within
Nuclear Medicine or radionuclide imaging procedures are noninvasive and
usually painless medical tests that help physicians diagnose medical conditions.
These imaging scans use radioactive materials called radiopharmaceuticals
Nuclear Medicine imaging scans are used to:
- Analyze kidney function
- Determine the presence or spread of cancer in various parts of the body
- Evaluate bones for fractures, infection, arthritis, and tumors
- Identify bleeding into the bowel
- Identify inflammation in the gallbladder
- 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
- Locate the presence of infections
- Measure thyroid function to detect an overactive or underactive thyroid
- Scan lungs for respiratory and blood flow problems
- Visualize heart blood flow and function (such as a myocardial perfusion scan)
- Physicians use radionuclide imaging procedures to visualize the structure
and function of an organ, tissue, bone or system of the body.
Nuclear Medicine therapies include:
- Radioactive iodine (I-131) therapy used to treat hyperthyroidism (overactive
thyroid gland, for example, Graves' disease) and thyroid cancer.
- Radioactive antibodies used to treat certain forms of lymphoma (cancer
of the lymphatic system).
- Radioactive materials used to treat painful tumor metastases to the bones.
