Radiologists use dianostic imaging technology like X-rays.
Radiology uses imaging technology to assist in diagnosing and treating injuries and diseases. Within the field there are differing technologies that require differing skill sets, education and certifications, ranging from technologists to medical doctors.
One Field, Many Technologies
Radiology encompasses diagnostic imaging technologies that utilize X-rays, sound waves, radioactive material and magnetic fields. X-rays are pictures taken with radiographs, fluoroscopy or computed tomography (CT scans). Sound waves produce ultrasound sonography (sonograms). Radioactive material is used in nuclear medicine for contrast imaging. The human body's own natural magnetism is used to produce magnetic resonance imaging (MRI).
Radiology Technician
The most basic certification in the field is for radiology technician (RT). These technicians assist the radiologist by operating the equipment to produce images. Most certification programs for this position begin with an associates degree that prepares the applicant to work with X-rays. A license is required.
Specialty Certifications
After licensing, radiology technicians may train for additional certifications in MRI, sonography or CT scans. Each area requires one year of training and a certification exam. Additional education is also required for working in nuclear medicine.
Advanced Radiological Degrees
Registered radiological assistants (RRA) must complete a bachelor's degree, have obtained licensure as an RT and must pass RRA certification requirements. They are responsible for evaluating image quality and making initial diagnostic observations. Certified radiology nurses (CRN) are registered nurses (RN) who specialize in patient care throughout imaging treatments. A radiologist is medical doctor who is assisted by the radiological team.
MRI Radiology Technicians
An MRI technician, like all the other positions, is a radiology technician; however, not all radiology technicians move beyond the entry level position to the specialty jobs requiring additional certifications and degrees.
