抄録

Organ and effective doses were evaluated for various head x-ray radiography and head CT examinations based on in-phantom dose measurements with photoluminescent glass and photodiode dosimeters. Brain doses were ranged between 0.46 and 1.08 mGy, in five different type of head radiography. Lens doses were the highest in the case where x-ray directly hit lens (e.g. head AP and Towne radiography) . The effective doses were in a range of 0.03-0.06 mSv. The effective dose for routine head CT examination was found to be 1.7 mSv, which was more than 50 times higher than that of head AP radiography. The maximum skin dose was as high as 712.0 mGy, in CT perfusion used in the diagnosis of acute brain infarction. The value, however, was lower than the threshold of 3 Gy (recommended value by the ICRP Publ. 59) for hair loss. Lens doses of 55.0 mGy for routine head CT examination and of 39.6 mGy for CT perfusion were also lower than the threshold value of 0.5 - 2.0 Gy (recommended value by ICRP Publ. 60) for clouded lens.
