PURPOSE
To evaluate the impact of virtual injection software (VIS) use during cone-beam computed tomography (CT)-guided prostatic artery embolization (PAE) on both patient radiation exposure and procedural time.
MATERIALS AND METHODS
This institutional review board (IRB)-approved comparative retrospective study analyzed the treatment at a single institution of 131 consecutive patients from January 2020 to May 2022. Cone-beam CT was used with (Group 1, 77/131; 58.8%) or without VIS (Group 2, 54/131, 41.2%). Radiation exposure (number of digital subtraction angiography [DSA] procedures), dose area product (DAP), total air kerma (AK), peak skin dose (PSD), fluoroscopy time (FT), and procedure time (PT) were recorded. The influences of age, body mass index, radial access, and use of VIS were assessed.
RESULTS
In bivariate analysis, VIS use (Group 1) showed reduction in the number of DSA procedures (8.6 ± 3.7 vs 16.8 ± 4.3; P < .001), DAP (110.4 Gy·cm ± 46.8 vs 140.5 Gy·cm ± 61; P < .01), AK (642 mGy ± 451 vs 1,150 mGy ± 637; P = .01), PSD (358 mGy ± 251 vs 860 mGy ± 510; P = .001), FT (35.6 minutes ± 15.4 vs 46.6 minutes ± 20; P = .001), and PT (94.6 minutes ± 41.3 vs 115.2 minutes ± 39.6, P = .005) compared to those in Group 2. In multivariate analysis, AK, PSD, FT, and PT reductions were associated with VIS use (P < .001, P < .001, P = .001, and P = .006, respectively).
CONCLUSIONS
The use of VIS during PAE performed under cone-beam CT guidance led to significant reduction in patient radiation exposure and procedural time.
目的
评估在锥形束计算机断层扫描（CBCT）引导下前列腺动脉栓塞术（PAE）中使用虚拟注射软件（VIS）对患者放射暴露和手术时间的影响。
材料与方法
本研究为机构审查委员会（IRB）批准的回顾性比较研究，分析了 2020 年 1 月至 2022 年 5 月在一家机构治疗的 131 例连续患者。使用（第 1 组，77/131；58.8%）或不使用 VIS（第 2 组，54/131，41.2%）进行 CBCT。记录放射暴露（数字减影血管造影[DSA]次数）、剂量面积乘积（DAP）、总空气比释动能（AK）、皮肤峰值剂量（PSD）、透视时间（FT）和手术时间（PT）。评估了年龄、体重指数、桡动脉入路和 VIS 使用的影响。
结果
在双变量分析中，VIS 使用（第 1 组）显示 DSA 次数（8.6 ± 3.7 与 16.8 ± 4.3；P <.001）、DAP（110.4 Gy·cm ± 46.8 与 140.5 Gy·cm ± 61；P <.01）、AK（642 mGy ± 451 与 1,150 mGy ± 637；P =.01）、PSD（358 mGy ± 251 与 860 mGy ± 510；P =.001）、FT（35.6 分钟 ± 15.4 与 46.6 分钟 ± 20；P =.001）和 PT（94.6 分钟 ± 41.3 与 115.2 分钟 ± 39.6，P =.005）均较第 2 组降低。在多变量分析中，AK、PSD、FT 和 PT 的降低与 VIS 的使用相关（P <.001、P <.001、P =.001 和 P =.006）。
结论
在锥形束 CT 引导下进行 PAE 时使用 VIS 可显著降低患者的放射暴露和手术时间。
