title: Patient doses from neuroradiological procedures.
abstract: Patient doses have been determined for a sample of 20 patients in a hospital department undergoing various interventional neuroradiological procedures. Skin entrance dose, dose-area product and effective dose have been estimated. Effective dose was estimated from published conversion factors. The highest dose on the patients body was recorded as the maximum skin entrance dose. The maximum skin entrance dose varied from 0.2 to 2.3 Gy. The largest maximum skin entrance dose is similar to the threshold for skin injuries (erythema). The effective dose varied from 2 to 34 mSv. The results of this study are compared with the results of other studies on radiation dose to patients from neuroradiological procedures.
