| Outline of Final Research Achievements |
Our IVR radiation support team assessed 1) whether lens radiation-shielding plate (LRSP) is useful for the reduction in radiation delivered to the eye lens during interventional neuroradiology (INR) procedures. and 2) whether the radiation map by GAFCHROMIC Film is useful for the radiation measurements during transcatheter arterial chemoembolization (TACE) in patients with hepatocellular carcinomas (HCCs).In results, the radiation map by RADIREC. showed a simple lens protective technique with the LRSP from the lateral X-ray projection is an easy and effective method for reducing eye dose during INR procedures. We also found that, in the HCC patients with TACE, the radiation map by GAFCHROMIC Film could detect patients with high risk radiation exposure.Our data suggest that the IVR radiation support team is useful for the clinical evaluation and management of patients based on their radiation exposure level.
