Nuclear Medicine

What is Nuclear Medicine?
Nuclear medicine procedures are tests performed by highly skilled professionals to diagnose a variety of diseases and disorders and learn about organ function through the use of radioactive materials.

What are the uses of Nuclear Medicine?
Nuclear medicine administers a radiopharmaceutical that targets specific organs. Some widely used tests include bone scans, cardiac imaging, hepatobiliary imaging, lung scans and thyroid scans and uptakes.

Is there any special preparation?
Below are specific preparation sheets that will give you more details. Be sure to find out how many scans are involved with your test and the time frame involved with each.

What is involved with Nuclear Medicine testing?
For the most part, scanning is simply a matter of lying on a table while the scanner does the work.

A radioactive compound called a radiopharmaceutical is introduced into the body by injection, ingestion or inhalation. This gives off gamma rays (similar to x-rays). The organ specific compound then travels through the body. A special camera is used at specified time intervals to detect the gamma rays and record them to create an image of the organ being examined. A computer stores these images which are recorded on film and studied for interpretation. Many tests require two scans.

Nuclear Medicine Lab Recognized
The Nuclear Medicine Department at St. Luke's Hospital has been granted accreditation by the Intersocietal Commission for the Accreditation of Nuclear Medicine Laboratories (ICANL). The St. Luke's nuclear laboratory is one of the first labs in the United States, Canada and Puerto Rico to be recognized by ICANL for a commitment to high quality patient care and diagnostic testing. The Nuclear Medicine Department was accredited for general nuclear medicine and nuclear cardiology.

Additional Information
Every precaution is taken when you have a nuclear medicine procedure. Exposure to radiation is low because only small quantities are needed for diagnosis. Exposure is short because the drugs lose most of their radioactivity in hours or days. Nuclear medicine procedures are carefully controlled. Facilities, equipment and materials meet strict safety standards. Safety is foremost in the minds of the nuclear medicine personnel.
