摘要： 目的前瞻性探讨三维增强磁共振血管成像(3D CE-MRA)技术在显示骶前区血管的可行性。方法选取40例因盆腔病变常规行MRI检查的成年患者,采用ACHIEVA 3.0T双源磁共振扫描仪对患者盆腔骶前区血管行DCE-MRA扫描,利用后处理工作站采用最大密度投影(MIP)及容积再现重组(VR)进行血管重建成像以最佳显示骶前区动脉及静脉,主要观察骶前区血管的影像学解剖。结果 40例骶正中动脉均显示清晰,成功率为100%;骶正中动脉均开口于腹主动脉分叉后上方,沿骶骨前面走行至尾骨尖,管径平均为(1.42±0.06)mm(1.30 mm～1.50 mm);骶前区静脉显示率为75%(30/40),可见骶前区静脉呈阶梯状分布。结论应用3D CE-MRA可以清晰显示部分骶前区血管,可为骶前区手术提供个体局部影像学解剖信息。

Abstract: Objective To explore the feasibility of three-dimensional enhanced magnetic resonance angiography (3D CE-MRA) in the presacral blood vessels. Methods 40 adult patients with pelvic lesions were examined by ACHIEVA 3.0T dual-source magnetic resonance scanner. DCE-MRA was used to scan the pelvic sacral anterior vessel. The maximal density projection (MIP) and the post volume reproducibility (VR) were reconstructed for optimal reconstruction of the anterior sacral arteries and veins, primarily to observe the anatomy of the anterior sacral vessels. Results 40 cases of sacral median artery were clear, the success rate was 100%; the sacral median arteries open in the abdominal aorta bifurcation after the top along the sacrum to the coccyx tip, the average diameter of (1.42±0.06) mm (1.30 mm-1.50 mm); the rate of the presacral venous display was 75% (30/40), showing that the anterior sacral vein was ladder-like distribution. Conclusion The application of 3D CE-MRA can clearly show some presacral blood vessels, which may provide individual local anatomical information for sacral precancerous surgery.
