Abstract

Recently, the number of interventional procedures has increased dramatically as an alternative of invasive surgical procedure and patient radiation exposure is also increasing accordingly. In this study, we evaluated the patient dose of major interventional procedures nationwide and we established our Korean database. With these results, we tried to suggest the reference dose level for major interventional procedures. We evaluated patent dose data in the field of interventional radiology from foreign countries. Measurement of radiation dose exposure for 11 major interventional procedures was conducted using embedded DAP meters in 10,006 patients from 47 hospitals, and reference level of each interventional procedure was suggested. The DRLs of each intervenional procedure are as follows: TACE 206(Gy·cm2), AVF 12(Gy·cm2), LE intervention 43(Gy·cm2), TFCA 122(Gy·cm2), Cerebral aneurysm coil embolization 214(Gy·cm2), PTBD 22(Gy·cm2), Biliary stent 60(Gy·cm2), PCN 7(Gy·cm2), Hickman catheter 2.1(Gy·cm2), Chemoport 1.4(Gy·cm2), BAE 104(Gy·cm2). Compared with the previously established DRL in 2012, the radiation dose decreased in all 10 interventional procedures. In the future, continuous publicity and education on the radiation dose reduction will be needed.
