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.
Computed tomography (CT), was originally known as CND scan as it was developed at a research branch of EMI, a company best known today for its music and recording business. It was later known as computed axial tomography (CAT or CT scan) and body section roentgenography. http://en.wikipedia.org/wiki/Computed_tomography. Magnetic resonance imaging (MRI) is primarily used in medical imaging to visualize the structure and function of the body. It provides detailed images of the body in any plane. http://en.wikipedia.org/wiki/Mri_scan.
