Applications of computerized tomography to diagnostic radiology

Computerized tomography (CT) has revolutionized the practice of diagnostic radiology. The combination of greatly improved ability to distinguish between regions of similar X-ray absorption and the ability to separate overlying regions from each other has made possible the radiographic demonstration of many organs and disease processes that previously could be, at best, poorly demonstrated. CT of the brain has greatly decreased the need for the dangerous and uncomfortable procedures that were previously required to image the brain. It has also improved imaging capabilities in many other areas of the body, and thus decreased the need for other, more dangerous, imaging techniques.
