Radiology has experienced radical advancement in a very short time since its inception a little more than a century ago. What is really impressive is that most of this advancement has taken place since the advent of computers in medical imaging. Computers marked the beginning of the digital era for radiology in the 1960s. Since then conventional film/screen x-ray imaging has been overshadowed by a plethora of digital medical imaging modalities that entered the clinical arena. In addition, the rapidly increasing availability and efficiency of computer technology have completely transformed all aspects of clinical radiology beyond image acquisition. Nowadays, computers are the cornerstone of technological innovations related to image display and interpretation, communication of imaging results, and clinical practice workflow in radiology. The term computer-assisted radiology (CAR) has been adopted to denote the clinical integration of computers and information technology to provide an environment of support to radiologists during the diagnostic interpretation of medical images.
