Abstract

Radiation doses for Computed Tomography (CT) procedures have been reported, including a total of 120 CT examinations conducted in radiology service of Hassan II hospital of Agadir.

This study consisted of examining the data of a total of 120 patients at the rate of 30 per localization. All CT examinations were performed with a GENERAL Electric 16 CT with Automatic Exposure Control System. The data that collected for each diagnostic exam chosen included scanner acquisition parameters, number of series, use of the contrast medium, and rotation time as well as slice thickness, the displayed CT dose index (CTDIvol) and the Dose Length Product (DLP). Effective dose and DRL were evaluated using the International Commission on Radiological Protection (ICRP) conversion factor and approach.

The average effective dose (Eeff), the displayed CT dose index (CTDIvol), dose length product (DLP) were 7, 28±2, 35 mSv, 10, 80±3, 80 mGy and 428, 35±138, 26 mGy.cm respectively at chest CT. For abdomen-pelvis CT, there were 12, 48±5, 58 mSv, 9, 30±2, 99 mGy and 805, 43±359, 98 mGy.cm respectively. Those at chest abdomen-pelvic CT were 11, 72±3, 98 mSv, 10, 82±2, 53 mGy and 755, 97±251, 52 mGy.cm respectively. For lumbar CT, there were 12, 12±2, 32 mSv, 26, 46±5, 24 mGy and 787, 00±14937 mGy.cm respectively.

Our values are lightly higher than the standards of some European countries. This first ever survey of CT practice in Hassan II Hospital of Agadir confirmed the need to improved training of health professionals involved in computed tomography on factors affecting image quality and dose and protocols optimization.
