To prospectively analyze the radiation exposure of patients and interventional radiologists during prostatic artery embolization (PAE).
Twenty-five consecutive PAE procedures performed with an Artis zee system in a single center by an interventional radiologist were prospectively monitored. The mean age, weight, and prostate volume of the patients were 65.7 year (range, 43-85 y), 71.4 kg (range, 54-88 kg), and 79 cm (range, 36-157 cm), respectively. In addition to Digital Imaging and Communications in Medicine radiation data, direct measures were also obtained. Radiochromic film was used to evaluate peak skin dose (PSD). The radiologist wore a protective apron and a thyroid collar, and a ceiling-suspended screen and a table curtain were used. To estimate the absorbed doses, nine pairs of dosimeters were attached to the operator's body.
The average fluoroscopy time was 30.9 minutes (range, 15.5-48.3 min). The mean total dose-area product (DAP) was 450.7 Gy·cm (range, 248.3-791.73 Gy·cm) per procedure. Digital subtraction angiography was responsible for 71.5% of the total DAP, followed by fluoroscopy and cone-beam computed tomography. The mean PSD was 2,420.3 mGy (range, 1,390-3,616 mGy). The average effective dose for the interventional radiologist was 17 μSv (range, 4-47 μSv); values for the eyes, hands, and feet were obtained, and were all greater on the left side.
PAE may lead to high x-ray exposures to patients and interventional radiologists.
前瞻性分析前列腺动脉栓塞术（PAE）过程中患者及介入放射科医生的辐射暴露情况。
前瞻性监测一位介入放射科医生在单一中心使用Artis zee系统连续进行的25例PAE手术。患者的平均年龄、体重和前列腺体积分别为65.7岁（范围43 - 85岁）、71.4千克（范围54 - 88千克）和79立方厘米（范围36 - 157立方厘米）。除医学数字成像和通信辐射数据外，还获取了直接测量值。使用放射变色胶片评估皮肤峰值剂量（PSD）。放射科医生穿戴防护围裙和甲状腺防护颈圈，并使用天花板悬挂式屏蔽和手术台帘。为估算吸收剂量，在操作者身体上附着了9对剂量计。
平均透视时间为30.9分钟（范围15.5 - 48.3分钟）。每次手术的平均总剂量面积乘积（DAP）为450.7 Gy·cm（范围248.3 - 791.73 Gy·cm）。数字减影血管造影占总DAP的71.5%，其次是透视和锥形束计算机断层扫描。平均PSD为2420.3 mGy（范围1390 - 3616 mGy）。介入放射科医生的平均有效剂量为17 μSv（范围4 - 47 μSv）；获取了眼睛、手部和足部的剂量值，且左侧的剂量值均更高。
PAE可能导致患者和介入放射科医生受到较高的X射线照射。
