In the last few decades, medical imaging technology has grown rapidly, and now MI technologists can take medical images of the human body in many different and sophisticated ways.
In nuclear medicine, radionuclides are used to diagnose and treat disease. Nuclear medicine technologists operate cameras that detect and map a radioactive drug in a patient’s body to create diagnostic images.
Ultrasound Technologist-Diagnostic Medical Sonographers
Ultrasound technologists operate ultrasound machines, using high frequency sound waves to create images of the inside of the body for diagnostic purposes. Sonography is commonly associated with obstetrics and the use of ultrasound imaging during pregnancy, but it is also used to make images of the abdomen, vascular system and heart.
A cardiovascular technologist or cardiovascular technician assists physicians in diagnosing and treating heart or blood vessel ailments.
Magnetic resonance technologists utilize the resonant frequency properties of atoms within a magnetic field to image anatomic and/or physiologic conditions of the body to assist physicians in the diagnosis and treatment of disease. They use non-ionizing radio frequency to generate image contrast.
CT (Computed Tomography) Technologists use ionizing radiation; therefore, it requires the same precautionary measures that are used with x rays.
Radiologic technicians and technologists take X-rays and administer nonradioactive materials into patients’ bloodstreams for diagnostic purposes.
Radiation therapists use ionizing-radiation producing equipment to administer therapeutic doses of radiation as prescribed by physicians for treatment of disease.
Imaging technologists make good money. A two year degree at a community college is all that’s required to be well compensated. Candidates for certification in Sonography or Magnetic Resonance Imaging must have either completed an ARRT-recognized educational program in that discipline or met the discipline’s post-primary eligibility requirements. The U.S. military also offers accredited programs: radiography by the Army and Air Force, radiography and nuclear medicine technology by the Navy. Completing all requirements of these programs qualifies as educational eligibility for ARRT certification.
