This study aimed to compare the lens equivalent dose (LED) measured during endoscopic retrograde cholangiopancreatography (ERCP) using DOSIRIS™ as a dedicated dosemeter to that measured using glass badges to determine if glass badges can be alternative tools for LED measurement. LEDs for physicians during ERCP were measured using the DOSIRIS™ [3-mm dose equivalent] worn on the outer edge of the eyes and personal dosemeters (glass badges) [0.07-mm dose equivalent] worn on the right and left sides of the neck. The cumulated doses over 6 months for the left eye using DOSIRIS™ were 9.5 and 11.8 mSv for physicians A and B, whereas doses measured using glass badges were 7.5 and 11.6 mSv, respectively. The LEDs of the physicians at the left eye and left neck side showed almost similar values and were significantly correlated (r = 0.95; p < 0.01). For an accurate LED measurement during ERCP, using a dosemeter such as DOSIRIS™ is recommended, although similar LED estimation values were reported using glass badges on the left neck side.
本研究旨在比较使用专用剂量计 DOSIRIS™ 在经内镜逆行胰胆管造影术（ERCP）期间测量的晶状体当量剂量（LED）与使用玻璃badge 测量的 LED，以确定玻璃badge 是否可以作为 LED 测量的替代工具。使用 DOSIRIS™（[3 毫米剂量当量]）测量 ERCP 期间医生右眼外侧和个人剂量计（玻璃badge）[0.07 毫米剂量当量]测量左、右颈侧的 LED。医生 A 和 B 在左眼使用 DOSIRIS™ 的 6 个月累积剂量分别为 9.5 和 11.8 mSv，而使用玻璃badge 测量的剂量分别为 7.5 和 11.6 mSv。左眼和左颈侧的医生 LED 显示出几乎相同的值，并呈显著相关（r = 0.95；p < 0.01）。对于 ERCP 期间的准确 LED 测量，建议使用 DOSIRIS™ 等剂量计，尽管在左侧颈侧使用玻璃badge 报告了类似的 LED 估计值。
