Today, imaging technologists perform a variety of diagnostic and therapeutic procedures. A registered technologist can work in many different clinical modalities such as: Diagnostic Radiology, Medical Sonography, Radiation Therapy, Mammography, CT, MRI, Nuclear Medicine, Bone Densitometry and Interventional Radiology.

Most radiology departments in hospitals include comprehensive medical imaging services. Diagnostic Radiology utilizes X-ray equipment for chest, extremities, all bony body parts, as well as fluoroscopic exams. Mammography performs diagnostic examinations of the breast. Diagnostic medical sonographers use high-frequency sound waves to produce images of internal body structures.

Interventional Radiology uses specialized X-ray equipment to evaluate neurological and vascular structures. They also help radiologists with procedures to open clogged arteries. Nuclear Medicine uses gamma cameras to locate radioactive materials introduced into the body to detect abnormalities.

Technologists also perform examinations that evaluate the anatomy and physiology of the body. Computerized tomography scanners (CT) provide complete body scanning and produce sectional images of internal body structures. Magnetic resonance imaging (MRI) uses radio waves, powerful magnets, and computers to create sectional images of internal body structures.

Radiation Therapists are key members of the oncology team that treats and cares for cancer patients.

You can become a registered radiologic technologist after successful completion of an accredited hospital, community college, or university based program and successful completion of the national accrediting examination. A minimum of an associate’s degree is required to take the national licensing examination. Additional training is required for program specialty areas.
