Distribution of ESDs in a patient with radiation skin injury. Neuroembolization for internal carotid-posterior communicating aneurysm was performed for a 43-year-old woman. The FOV mainly used was 14 cm. Total fluoroscopic time and DAP were 75.0 minutes and 182 Gy × cm2, respectively; 4° left anterior oblique with 17° cranial angulation view was mostly used. Exposed skin area was localized to the occipital region with the maximum ESD of 3.0 Gy. Temporary epilation was detected at the maximum exposure part (slanted lines) at 2 weeks and 3 months of follow-up. The number in the open square represents the ESD (Gy) at the point. — in the open square means the ESD at the point was less than 0.3 Gy.
