Abstract
Following the discovery of X-rays by Roentgen in 1895, it was 70 years later that the specialty of imaging really took off, with ultrasound, CT, Nuclear medicine, and MRI now an integral part of all large departments. The recent progress has been accelerated by advances in computer technology which aided the development of imaging techniques that do not use ionising radiation. Some imaging techniques are replacing other more hazardous diagnostic procedures, (eg MRCP v ERCP, and MRA v catheter angiography) while some are able to provide almost perfect anatomical detail e.g.brain MRI. Techniques using radioisotopes provide more functional information which can be used to complement the morphological studies. We have witnessed the birth and maturation of Interventional Radiology. This is a highly skilled subspecialty enabling some surgical procedures to be replaced by minimally invasive methods using image guidance. These range from simple drainage procedures and guided biopsies to complex aortic bifurcation stent graft insertions. The potential for digital storage of all images is already established and the filmless radiology department in the more developed countries could be the norm by 2020.
