To report dosimetry of commonly performed interventional radiology procedures and compare dose analogues to known reference levels.
Demographic and dosimetry data were collected for gastrostomy, nephrostomy, peripherally inserted central catheter placement, visceral arteriography, hepatic chemoembolization, tunneled catheter placement, inferior vena cava filter placement, vascular embolization, transjugular liver biopsy, adrenal vein sampling, transjugular intrahepatic portosystemic shunt (TIPS) creation, and biliary drainage between June 12, 2014, and April 26, 2018, using integrated dosimetry software. In all, 4,784 procedures were analyzed. The study included 2,691 (56.2%) male subjects and 2,093 (43.8%) female subjects with mean age 55 ± 21 years (range: 0-104 years) and with mean weight of 76.9 ± 29.4 kg (range: 0.9-268.1 kg). Fluoroscopy time, dose area product (DAP), and reference dose were evaluated.
TIPS had the highest mean fluoroscopy time (49.1 ± 16.0 min) followed by vascular embolization (25.2 ± 11.4 min), hepatic chemoembolization (18.8 ± 12.5 min), and visceral arteriography (17.7 ± 3.2 min). TIPS had the highest mean DAP (429.2 ± 244.8 grays per square centimeter [Gy·· cm]) followed by hepatic chemoembolization (354.6 ± 78.6 Gy·· cm), visceral arteriography (309.5 ± 39.0 Gy·· cm), and vascular embolization (298.5 ± 29 Gy·· cm). TIPS was associated with the highest mean reference dose (2.002 ± 1.420 Gy) followed by hepatic chemoembolization (1.746 ± 0.435 Gy), vascular embolization (1.615 ± 0.381 Gy), and visceral arteriography (1.558 ± 1.720 Gy). Of the six procedures available for comparison with the reference levels, the mean fluoroscopy time, DAP, and reference dose for each procedure were below the proposed reference levels.
Advances in image acquisition technology and radiation safety protocols have significantly reduced the radiation exposure for a variety of interventional radiology procedures.
报告常见介入放射学程序的剂量学，并将剂量指标与已知参考水平进行比较。
2014 年 6 月 12 日至 2018 年 4 月 26 日，使用集成剂量学软件收集胃造口术、肾造口术、经外周插入中心静脉导管置管术、内脏血管造影术、肝动脉化疗栓塞术、隧道导管置管术、下腔静脉滤器置放术、血管栓塞术、经颈静脉肝活检术、肾上腺静脉取样术、经颈静脉肝内门体分流术（TIPS）创建和胆道引流术的人口统计学和剂量学数据。共分析了 4784 例程序。该研究包括 2691 名（56.2%）男性和 2093 名（43.8%）女性受试者，平均年龄 55 ± 21 岁（范围：0-104 岁），平均体重 76.9 ± 29.4kg（范围：0.9-268.1kg）。评估了透视时间、剂量面积乘积（DAP）和参考剂量。
TIPS 的平均透视时间最长（49.1 ± 16.0 分钟），其次是血管栓塞术（25.2 ± 11.4 分钟）、肝动脉化疗栓塞术（18.8 ± 12.5 分钟）和内脏血管造影术（17.7 ± 3.2 分钟）。TIPS 的平均 DAP 最高（429.2 ± 244.8 戈瑞每平方厘米[Gy·cm]），其次是肝动脉化疗栓塞术（354.6 ± 78.6 Gy·cm）、内脏血管造影术（309.5 ± 39.0 Gy·cm）和血管栓塞术（298.5 ± 29 Gy·cm）。TIPS 的平均参考剂量最高（2.002 ± 1.420 Gy），其次是肝动脉化疗栓塞术（1.746 ± 0.435 Gy）、血管栓塞术（1.615 ± 0.381 Gy）和内脏血管造影术（1.558 ± 1.720 Gy）。在与参考水平比较的六种程序中，每种程序的平均透视时间、DAP 和参考剂量均低于建议的参考水平。
影像采集技术和辐射安全协议的进步显著降低了各种介入放射学程序的辐射暴露。
