| Research Abstract |
We established a direct dosimetry method of patients’ entrance skin doses during neuroendovascular procedure using multiple radiophotoluminescence glass dosimeters. We applied this dosimetry system in clinical neuroendovascular settings, and clarified the frequency of maximum entrance skin dose (ESD) over 3 Gy, the prevalence of temporary epilation as a radiation-induced skin injury, and the difference of radiation-dose distributions between single-plane and bi-plane angiography equipments. In addition, we clarified that total fluoroscopic time and dose-area products were clearly related to maximum ESD and we could estimate the ESD in real-time during neuroendovascular procedure. These results could be the fundamental data to reduce radiation exposure during neuroendovascular procedure and to apply the radioprotective agent in a clinical setting in the near future.
