Employment of nuclear medicine technologists is projected to grow 2 percent from 2014 to 2024, slower than the average for all occupations. An aging population may lead to the need for nuclear medicine technologists who can provide imaging to patients with certain medical conditions, such as heart disease. However, employment growth may be tempered as many medical facilities and third-party payers encourage the use of less costly, noninvasive imaging technologies, such as ultrasound.
