They also position radiographic equipment at the correct angle and height over the appropriate area of a patient’s body. They prepare patients for radiologic examinations and position patients so that the parts of the body can be appropriately radiographed. Radiologic technicians, sometimes referred to as radiographers, produce x-ray films (radiographs) of parts of the human body for use in diagnosing medical problems. They work closely with radiologists, the physicians who interpret medical images to either diagnose or rule out disease or injury. Radiologic technologists who perform imaging examinations are responsible for accurately positioning patients and ensuring that a quality image is produced. Unlike CT and x-rays, MRI uses non-ionizing radio frequency to generate image contrast. Radiologic technologists might also specialize in mammography. MRI, like CT, produces multiple cross-sectional images to create a 3-dimensional image. Radiologic technologists also can specialize in MRIs, as MRI technologists. CT scans produce a substantial amount of cross-sectional x-rays of an area of the body from which a 3-dimensional image is made. Some radiologic technologists specialize in computed tomography (CT), as CT technologists. When performing fluoroscopies, for example, radiologic technologists prepare a solution for the patient to drink, allowing the radiologist (a physician who interprets radiographs) to see and examine soft tissues in the body. Radiologic technologists perform more complex imaging procedures. Radiologic technologists use imaging modalities such as computed tomography, magnetic resonance imaging (MRI), and mammography, while radiologic technicians perform imaging examinations like x-rays. Radiologic technologists and technicians perform diagnostic imaging examinations. What Do Radiologic Technologists and Technicians Do?
