Detailed Guide for

Nuclear Medicine Technologists in California

May also be called: Nuclear Medical Technologists; and Nuclear Medicine Technicians

What Would I Do?

Nuclear medicine technology provides imaging of microscopic biological changes in the body. These detailed images provide data to identify diseases and conditions that are not possible with other diagnostic imaging technologies. The images document how well tissues and organs function rather than physical changes in their shape or structure. This allows for identifying abnormalities sooner than other diagnostic tests.

Nuclear Medicine Technologists, working under the direction of a doctor, administer radioactive compounds or drugs, known as radiopharmaceuticals, to patients. These substances are designed to target specific tissues or organs in the body. Special computerized cameras detect the distribution of radiopharmaceuticals to create images of specific areas in the body. After explaining test procedures to patients, Technologists prepare an appropriate dosage of the radiopharmaceutical to be swallowed, injected, inhaled, or taken by other means. After a specific waiting period, they position patients and start a specialized camera. The camera works with a computer to provide a high-resolution image.

When preparing radioactive drugs, Technologists comply with safety standards that keep the workers' and patients' exposure to radiation as low as possible. Technologists make sure the patient has been properly prepared for the procedure. They also keep patient records and document the amount and type of radioactive drugs that the Technologist obtains for the patient, uses, and discards.

Nuclear medicine is a specialty of radiology. Because radiopharmaceuticals are designed to target a variety of tissues, the body parts that nuclear medicine can image are numerous. One use is cardiovascular imaging. This traces a radioactive drug, which attaches to red blood cells, as it passes through the heart's chambers.

This field of medicine also treats abnormalities or diseases by destroying targeted tissue. For instance, a cancer patient is given a radiopharmaceutical designed to bind to specific cancer cells. This compound targets and destroys the cancer cells, making it more effective than conventional external radiation techniques. In addition, stronger doses of radiation can be administered this way than would be safe through a conventional external radiation treatment. As new compounds are created by combining radioactive materials with drugs attracted to other tissues, opportunities to use nuclear medicine increase.

Tools and Technology

The positron emission tomography (PET) procedure uses a special medical imaging device, shaped like a doughnut, which produces a three-dimensional image of the body. The PET can detect the precise locations of radiation concentrations imaging metabolic abnormalities linked to disease. Another technique is the single photon emission computed tomography (SPECT) which uses a camera that moves around the body to create a three-dimensional image. The PET and SPECT images can be combined with images from other imaging technologies to provide even more informative data.

Nuclear Medicine Technologists also use hypodermic needles, gamma cameras, liquid scintillation counters, medical software for the cameras, office suite software, radiation detectors, radiation dosimeters, and spectrometers.

Working Conditions

Most Nuclear Medicine Technologists work in clean, medical environments, such as hospitals, doctors' offices, or mobile imaging vehicles. Physical stamina is important in any setting because Nuclear Medicine Technologists are on their feet much of the day and may have to lift or turn disabled patients. In addition, Technologists must operate complicated equipment that requires mechanical ability and manual dexterity.

Because radioactive material can cause harm to people and the environment, use of these materials is highly regulated. While the potential for radiation exposure exists, it is minimized by the use of shielded syringes, gloves, and other protective devices and by following strict safety guidelines. Technologists also wear badges that measure radiation levels. The amount of radiation in a nuclear medicine procedure is comparable to that received during a diagnostic X-ray procedure.

Nuclear Medicine Technologists generally work a 40-hour week. Technologists may work evening and weekend hours in departments that operate on an extended schedule. They may work on call or part-time. In addition, Technologists in hospitals may have on-call duty on a rotational basis, and those employed by mobile imaging services may be required to travel to several locations.

Although some hospitals have unions, the health care industry is not heavily unionized.

Will This Job Fit Me?

This occupation may appeal to those who like searching for facts and figuring out problems mentally. People who like working with ideas and desire to continue learning may enjoy this occupation. It is valuable for Nuclear Medicine Technologists to be detail-oriented and meticulous when performing procedures to assure that all regulations are being followed.

It is beneficial for Technologists to have good communication skills to interact with patients and their families. They should be sensitive to patients’ physical and psychological needs and have a genuine concern for the welfare of patients and clients. The ability to deal with people of diverse backgrounds in stressful situations is valuable.

Typical benefits include medical, dental, life, and vision insurance as well as vacation, sick leave, and retirement plans. Employers frequently provide tuition reimbursement. Several employers also provide assistance with continuing education, such as time off to attend courses and employer-provided training.

What is the Job Outlook?

The technological developments in nuclear medicine treatments and the increase in the middle-aged and elderly populations will likely increase the use of nuclear medicine. The use of technologies, including PET and SPECT, is expected to increase and contribute to employment growth. The wide use of nuclear medical imaging to observe metabolic and biochemical changes during neurology, cardiology, and oncology procedures also will spur demand for Nuclear Medicine Technologists. However, new procedures will likely replace older technologies, keeping the actual number of job openings relatively low.

In addition, the cost for the procedures will be a factor that limits growth. Some promising nuclear medicine procedures are extremely costly. Facilities contemplating these procedures will have to consider equipment costs, reimbursement policies, and the number of potential users. Technologists who are trained in multiple diagnostic methods should have the best job prospects.
