| Outline of Final Research Achievements |
Interventional cardiology, such as percutaneous coronary intervention (PCI), are increasingly being adopted in the treatments for coronary artery disease. Unfortunately, several cases of skin injury caused by radiation exposure are still being reported in association with PCIs. Furthermore, coronary computed tomography (CT), which is a promising non-invasive technique for the detection of coronary stenosis, is increasingly utilized for the preoperative examination and postoperative assessment of PCI. Compared to other CT examinations, coronary CT examinations deliver a higher dose. In addition, many CT protocols do not provide a method for evaluating the patient entrance skin dose. Thus, high radiation doses may have deterministic effects. Using multiple radiophotoluminescence glass dosimeters with a modified dosimetry gown to measuring the entrance skin doses in PCI and coronary CT, we developed a comprehensive radiation exposure management protocol to prevent radiation skin injuries.
