Radiologists are medical specialists who, after completing their medical degrees, specialize for another four years in the interpreting of X-rays and scans. Training involves learning to understand and interpret images from X-rays, ultrasound, CT and MRI as well as advising referring doctors on the best ways of imaging (getting results and images) for specific problems. Radiologists work in collaboration with referring doctors and specialists, providing advice and are always available to discuss the results of diagnostic tests and examinations with their patients.


Radiographers form part of the diagnostic team by operating the equipment and producing the X rays or images used by the radiologists to make their diagnosis. An important part of their job is to explain the procedure to the patient and ensure that the equipment is used optimally. Radiographers qualify through formal training of up to four years and may go on to work exclusively in a specialist field of radiology.
