Purpose
Background:
Cardiac interventional radiology procedures such as percutaneous coronary intervention (PCI) have been increasing year by year because of their low invasiveness compared to surgical operations such as coronary artery bypass grafts.
Although numerous case reports of patient radiation injury resulting from PCI are increasingly being published,
these reports likely represent a small fraction of the actual cases.
Once,
we had examined the prospective study to identify radiation injuries after PCI.
Although mild erythema occurred (Fig.1),
we observed six cases (1.5%) of radiation skin injury in 400 consecutive PCIs.
The occurrence rate of skin injury in our study was higher than previously reported.
Learning objectives:
Radiation skin injuries have been still reported.
There is a necessity to measure the patient entrance skin dose (ESD),
but accurate dose measurement method has not been established.
We examined to build a direct measurement system to determine accurate ESD and its mapping using multiple radiophotoluminescence glass dosimeters (RPLDs) in cardiac interventional procedure.
