In 17 patients who underwent prostate artery embolization for treatment of lower urinary tract symptoms, the accuracy of preprocedural magnetic resonance (MR) angiography was retrospectively compared with intraprocedural digital subtraction angiography (DSA) in the identification of prostatic artery origin. Of 34 vessels, 26 MR angiography identified origins (76.5%) were confirmed by DSA at the time of embolization. Although image postprocessing is required, the ability of MR angiography to accurately identify prostatic artery origins prior to embolization is useful in treatment planning and can obviate the need for separate computed tomographic angiography, thus reducing both radiation dose and time demand on patients.
在 17 例行前列腺动脉栓塞术治疗下尿路症状的患者中，回顾性比较了术前磁共振（MR）血管造影术与术中数字减影血管造影（DSA）在识别前列腺动脉起源中的准确性。在 34 条血管中，26 条（76.5%）MR 血管造影术识别的起源在栓塞时通过 DSA 得到证实。虽然需要进行图像后处理，但 MR 血管造影术在栓塞前准确识别前列腺动脉起源的能力有助于治疗计划，并可以避免单独进行计算机断层血管造影术，从而减少患者的辐射剂量和时间需求。
