Abstract

To optimize the radiation protection of patients, we investigated the possibility of constructing the diagnostic reference levels (DRLs) by imaging objective/disease group using display value of the blood vessel imaging apparatus (air kerma-area product: P_KA, air kerma at the patient entrance reference point: K_{a, r}) in cerebral angiography. We used P_KA and K_{a, r} recorded during surgery of 997 patients at our hospital, and classified them according to the purpose of imaging (diagnostic cerebral angiography or neuro interventional radiology) and disease group. Neuro interventional radiology (P_KA: 268±155 Gy・cm², K_{a, r}: 2420±1462 mGy) was significantly higher than that of diagnostic cerebral angiography (P_KA: 161±70 Gy・cm², K_{a, r}: 1112±485 mGy), (Mann-Whitney test, P<0.01). Significant difference was found between P_KA and K_{a, r} for imaging purpose and disease group (Kruskal-Wallis test, P<0.05). It is highly probable that the DRL for cerebral angiography can be constructed by imaging purpose/disease group using display value (P_KA, K_{a, r}) of the blood vessel imaging apparatus.
