An Introduction to Diagnostic Radiology from the Chief Censor in Radiology

The discovery of X-rays in 1895 by Wilhelm Roentgen heralded the arrival of a totally new method of medical diagnosis. The past century has witnessed an explosion in the increasingly sophisticated utilisation of X-rays and other energy sources such as radioisotopes (nuclear medicine), ultrasound and magnetic resonance imaging to enable us to provide a very accurate display of human anatomy, pathology and physiology. Modern diagnostic imaging methods clearly define a huge variety of disease processes, and also allow evaluation of the effects of treatment. The newer imaging modalities also enable the diagnostic radiologist to undertake sophisticated interventional and therapeutic procedures.

Radiology is now central to the clinical practice of medicine across a wide range of disciplines. It is the best practical way to diagnose, monitor treatment and detect progression or relapse of many important and common diseases in a minimally invasive and anatomically precise manner. As a consequence of the increasing sophistication and accuracy of clinical imaging, the utilisation and importance of radiology has increased dramatically and consistently over the last 20 years. There is a greater and greater need for more radiologists of increasingly better quality and skills, and this shows no sign of abating. It is also a highly portable profession, specific national and state regulations notwithstanding.
