Evaluation Of Image Enhancement Using Different Protocols For Routine Thorax Computed Tomography Examination On 16-Slice Scanners In Two Tertiary Hospitals

The purposes of this study were to evaluate and compare the degree of contrast enhancement and image quality of routine thorax computed tomography (CT) examination on 16-slice scanner in two hospitals using two different protocols. The two protocols named as; 1) automatic bolus tracking (ABT), which...
