Nuclear Medicine

Nuclear medicine is a subspecialty within the field of medical imaging. It comprises diagnostic examinations that result in images of organ’s anatomy and physiology. The images are developed based on the detection of energy emitted from a radioactive tracer given to the patient, either intravenously or by mouth. Generally, radiation to the patient is similar to that resulting from X-Ray or CT exams.

The patient is given a small dose of radioactive tracer that localizes in specific organ systems. These radiopharmaceuticals collect in the organ of interest at different rates and give off energy as gamma rays. At the appropriate time the gamma camera will be used to detect the rays and work with a computer to produce images and measurements of organs and tissues.

While the images are being obtained, the patient must remain as still as possible. The patient will usually be positioned lying flat on a standard imaging table. Imaging time ranges from 1 minute to 2-hours depending on exam. Some exams require multiple appointments, the scheduler will make sure you understand the timing of appointments when they talk with you.

A physician who has specialized training in nuclear medicine will interpret the images and forward a report to your physician. It takes few business days to interpret images and finalize a report for you and your provider.
