Effects of radiologists' skill and experience on patient doses in interventional examinations

In this study, effects of radiologists' skill and experience on patient doses were investigated. Dose-area product and entrance surface doses of two groups of patients, one examined by a number of junior radiologists and another one by a senior radiologist, have been compared for the diagnostic interventional examinations of cerebral and lower limbs. Collimation of the X-ray beam and shortening the fluoroscopy times by the senior radiologist considerably reduced the patient doses for interventional cerebral examinations. (authors)
