Our study aims to evaluate the value of 256-slice dual-energy computed tomography (DECT) in supporting prostatic artery embolization (PAE) under digital subtraction angiography (DSA) for benign prostatic hyperplasia (BPH). The study was conducted on 88 patients who underwent PAE to treat BPH from January 2022 to November 2023. Of these, 38 patients who had PAE without DECT were placed in group 1, while the other 50 patients with pre-interventional DECT were assigned to group 2. The results of DECT imaging of the prostate artery (PA) were compared with the results of DSA imaging. Test for statistically significant differences between the variables of the two research groups using the T - student test and Mann-Whitney test algorithms with p < 0.05 corresponding to a 95% confidence interval. The data were analyzed according to medical statistical methods using SPSS 20.0 software. DECT can detect the PA origin in 96.1% of cases, identify atherosclerosis at the root of the artery with a sensitivity of 66.7% and a specificity of 89.5%, and present anastomosis with a sensitivity of 72.7% and a specificity of 72.2%. There is no statistically significant difference in PA diameter on DECT compared to DSA with 95% confidence. Group 2 used DECT for 3D rendering of the PA before PAE had procedure time reduced by 25.8%, fluoroscopy time reduced by 23.2%, dose-area product (DAP) reduced by 25.6%, contrast medium volume reduced by 33.1% compared to group 1 not using DECT, statistically significant with 95% confidence. DECT is a valuable method for planning before PAE to treat BPH. 3D rendering DECT of PA provides anatomical information that minimizes procedure time, fluoroscopy time, dose-area product, and contrast medium volume.
我们的研究旨在评估 256 层双能计算机断层扫描（DECT）在数字减影血管造影（DSA）下支持前列腺动脉栓塞（PAE）治疗良性前列腺增生（BPH）的价值。这项研究共纳入了 2022 年 1 月至 2023 年 11 月期间接受 PAE 治疗 BPH 的 88 例患者。其中，38 例未行 DECT 检查的患者被归入组 1，50 例行 PA 介入前 DECT 检查的患者被归入组 2。对比两组患者的前列腺动脉（PA）DECT 成像结果与 DSA 成像结果。采用 T 检验和曼-惠特尼检验算法比较两组研究变量之间的差异，p＜0.05 表示 95%置信区间有统计学意义。使用 SPSS 20.0 软件进行医学统计分析。DECT 可检测 96.1%的病例中 PA 的起源，对动脉根部粥样硬化的敏感性为 66.7%，特异性为 89.5%，吻合口的敏感性为 72.7%，特异性为 72.2%。DECT 与 DSA 比较，PA 直径无统计学差异（95%置信区间）。与未行 DECT 检查的组 1 相比，组 2 在 PAE 前使用 DECT 进行 3D 渲染，使手术时间缩短了 25.8%，透视时间缩短了 23.2%，剂量面积乘积（DAP）降低了 25.6%，造影剂用量减少了 33.1%，差异有统计学意义（95%置信区间）。DECT 是治疗 BPH 前 PAE 的一种有价值的方法。PA 的 3D 渲染 DECT 提供了解剖学信息，可最大程度地缩短手术时间、透视时间、剂量面积乘积和造影剂用量。
