Radiologists examine and analyze diagnostic images.
The Bureau of Labor Statistics projects that radiologic technologist jobs will increase by 17 percent between 2008 and 2018. Likewise, employment of physicians and surgeons -- including radiologists -- are expected to rise by 22 percent during the same period. Factors such as an aging and expanding population, and technological advances in the medical industry will drive job growth in the radiology field. As diagnostic imaging is increasingly used to treat diseases and injuries, radiology professionals will be needed to meet hiring demands.
Function
Radiologists are physicians who use X-ray machines, computed tomography (CT) scans, magnetic resonance imaging (MRI) machines, and other medical imaging technology to assess and treat diseases and injuries. After reviewing and analyzing the medical images, radiologists communicate their results to primary care physicians to formulate a proper treatment plan for the patient. Working closely with radiologists are radiologic technologists and technicians. These professionals help prepare patients for diagnostic imaging examinations by explaining common procedures, positioning patients under radiographs and placing protective coverings over the patient's body. Other duties assigned to technologists and technicians include monitoring and adjusting radiograph settings, updating patient records and preparing work schedules.
Education
Similar to other physicians, radiologists must successfully an undergraduate program and four years of medical school. After receiving their doctor of medicine (M.D.) degree, candidates must then enter a radiology residency. Residencies typically last from four to five years and encompass lectures, conferences and on-the-job training with imaging technology. Radiologic technicians and technologists have the option of pursuing a certificate, associate or bachelor's degree in radiology accredited by the Joint Review Committee on Education in Radiologic Technology (see Resources). Students in radiology training programs can expect to take courses covering subjects such as imaging principles, medical ethics, radiobiology and pathology.
Skills
Radiologists must be highly knowledgeable about imaging technologies, diseases, treatments and scanning procedures. Often, patients are referred to radiologists by their primary care physicians. Being able to clearly communicate complex procedures to medical staff is important when constructing an appropriate treatment plan for patients. Superior analytical and decision-making skills are also required as a radiologist. Radiologic technicians and technologists must also have a strong attention to detail and be able to follow directions assigned by radiologists. Good patient relations skills and the ability to operate complex equipment are also necessary as a radiologic technician.
Certification
In addition to passing the United States Medical Licensing Examination (USMLE), radiologists must obtain certification through the American Osteopathic Board of Radiology or the American Board of Radiology (see Resources). Licensing for radiologic technicians and technologists vary by state. Technologists can obtain voluntary certification through the American Registry of Radiologic Technologists (ARRT). Although licensure is not mandatory, most employers prefer candidates with ARRT certification. Radiologic professionals must complete 24 hours of continuing education every two years in order to maintain certification (See Resources).
