About Radiology

Radiology is a part of medical science that specialises in the diagnosis of diseases by obtaining and interpreting medical images.

Medical images are obtained in a variety of ways. Some by using X-rays or radioactive substances, others by using sound waves or the body's natural magnetism. Results may be combined with other examinations and tests to help decide on the most appropriate treatment.

The field of Radiology includes diagnosis (and treatment) for all ages and across and inside all parts of the human body. Because there are so many aspects to the radiology there can be various 'sub-specialties' where doctors and their staff specialize in a specific parts of the body or uses of radiological technology.

The Radiology team


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.

For Patients

The Radiological Society of South Africa is a professional association dedicated to improving the quality of patient care. Members of the RSSA are diagnostic radiologists, throughout South Africa and Namibia, who are involved in continual review of ways and means to improve services, tests and technologies.

The RSSA promotes improved professional development and education, both for members and allied health professions. RSSA sets performance standards and provides clinical and billing guidelines to assist members in their commitment to professional standards.

For Medical Aids

The RSSA promotes constructive interaction and co-operation between radiologists and our colleagues in affiliated industries. Through ongoing programs of peer review, clinical guidelines and guidelines to billing it demonstrates our commitment to ensure adherence to standards and eradication of fraud. RSSA employs a specific peer review committee whose mandate is to continually review and issue guidelines to billing. The RSSA endorses and has adopted the guidelines of the Australasian College of Radiology. Relationships with members enables the RSSA to co-operate in data-sharing and accumulation of information to assist with problem solving and various proactive initiatives.
