Radiology technologists are involved in direct patient care. Radiographers position imaging equipment and adjust controls to produce diagnostic quality images and assist radiologists in performing specialized imaging procedures. Radiographers work in a variety of settings including hospitals, diagnostic centers, doctor's offices, clinics, and orthopedic practices. Certified radiology technologists may go on to be trained in other advanced imaging techniques, including Computed Axial Tomography (CAT), Magnetic Resonance Imaging (MRI), and Positron Emission Tomography (PET), mammography, and interventional radiography. Advanced career options in education, administration and research are also possible.
