Nuclear medicine technologists use a scanner to create images of various areas of a patient’s body. They prepare radioactive drugs and administer them to patients undergoing the scans. The radioactive drugs cause abnormal areas of the body to appear different from normal areas in the images.
Nuclear medicine technologists typically do the following:
Radioactive drugs, known as radiopharmaceuticals, give off radiation, allowing special scanners to monitor tissue and organ functions. Abnormal areas show higher-than-expected or lower-than-expected concentrations of radioactivity. Physicians then interpret the images to help diagnose the patient’s condition. For example, tumors can be seen in organs during a scan because of their concentration of the radioactive drugs.
