Radiation Dose to Eye Lens and Gonads During Transfemoral Cerebral Angiography

Ninety-two randomly selected patients undergoing transfemoral cerebral angiography were studied to determine eye lens and gonadal radiation exposures. The mean individual lens exposure was 12.4 rads with a range of 0.5 rad to 35.5 rads. The mean gonadal exposure was below 0.004 rad for all but one patient. The right eye received a mean dose 28% greater than the left in 82% of cases. The mean lens exposure increased proportionately to the mean...
