They ensure all forms are completed and properly identified and signed, and all necessary information is in the computer. Sometimes, they talk to physicians or others to clarify diagnoses or get additional information. In nuclear medicine, radionuclides unstable atoms that emit radiation spontaneously are used to diagnose and treat disease. Radionuclides are purified and compounded like other drugs to form radiopharmaceuticals. Nuclear medicine technologists administer these radiopharmaceuticals to patients, then monitor the characteristics and functions of tissues or organs in which they localize.
Abnormal areas show higher or lower concentrations of radioactivity than normal.
Nuclear medicine technologists operate cameras that detect and map the radioactive drug in the patient s body to create an image on photographic film or a computer monitor. Radiologic technologists also operate diagnostic imaging equipment, but their equipment creates an image by projecting an x ray through the patient. Nuclear medicine technologists explain test procedures to patients. They prepare a dosage of the radiopharmaceutical and administer it by mouth, injection, or other means. When preparing radiopharmaceuticals, technologists adhere to safety standards that keep the radiation dose to workers and patients as low as possible.
