The Evolution of CT Scan Clinical Trials. Submitted by Bioclinica on July 22, 2011 - 11:46am. On October 1, 1971, CT scanning was first introduced by Godfrey Hounsfield into medical practice with a successful scan on a patient at the Atkinson Morley Hospital in Wimbledon, London using a prototype scanner.
Coronary CT angiography (CTA) is the use of CT angiography to assess the coronary arteries of the heart. The subject receives an intravenous injection of radiocontrast and then the heart is scanned using a high speed CT scanner, allowing radiologists to assess the extent of occlusion in the coronary arteries, usually in order to diagnose coronary artery disease.
