With the advent of "state-of-art" digital subtraction angiography units, there is a need to re-establish the radiation dose related data during procedures performed using such machines. Radiation doses to patients and staff during cerebral angiographic procedures were measured using thermo-luminescent dosimeter and dose-area-product meter. Mean effective dose to patient during cerebral angiogram procedure was found to be 4.6 mSv and that to radiologist was 0.005 mSv. On the basis of these findings, methods to optimize doses received patients during these procedures are discussed.
