背景与目的：关于支架盘绕后动脉瘤无创随访的资料很少。我们的目的是比较飞行时间（TOF）磁共振血管造影（MRA） （3D-TOF-MRA）和对比增强MRA （CE-MRA）在3-特斯拉，与数字减影血管造影（DSA）评估动脉瘤闭塞和载动脉通畅后支架辅助线圈。材料和方法：在这项回顾性单中心研究中，纳入了2008年3月至2015年6月期间接受支架辅助卷取治疗的颅内动脉瘤患者，随后在3-Tesla和DSA下进行MM序列（3D-TOF-MRA和CE-MRA），间隔< 48小时。结果：共纳入35个动脉瘤。在动脉瘤闭塞评估方面，CE-MRA与DSA的一致性（K=0.53）优于3D-TOF-MRA （K= 0.28）。3D-TOF-MRA和CE-MM对动脉瘤残余描述的诊断准确性相似（P=1）。与DSA相比，3D-TOF-MRA （K=0.05）和CE-MRA （K= 0.04）均无法检测到病变血管，准确性无差异（P= 0.68）。对于母动脉闭塞的检测，3D-TOF-MRA与DSA的一致性较高（K=0.64）， CE-MRA与DSA的一致性较低（K= 0.45），两者的诊断准确性相似（P=1）。
Background and purpose: Data about non-invasive follow-up of aneurysm after stent-assisted coiling is scarce. We aimed to compare time-of-flight (TOF) magnetic resonance angiography (MRA) (3D-TOF-MRA) and contrast-enhanced MRA (CE-MRA) at 3-Tesla, with digital subtraction angiography (DSA) for evaluating aneurysm occlusion and parent artery patency after stentassisted coiling.Materials and methods: In this retrospective single-center study, patients were included if they had an intracranial aneurysm treated by stent-assisted coiling between March 2008 and June 2015, followed with both MM sequences (3D-TOF-MRA and CE-MRA) at 3-Tesla and DSA, performed in an interval < 48 hours.Results: Thirty-five aneurysms were included. Regarding aneurysm occlusion evaluation, agreement with DSA was better for CE-MRA (K=0.53) than 3D-TOF-MRA (K= 0.28). Diagnostic accuracies for aneurysm remnant depiction were similar for 3D-TOF-MRA and CE-MM (P=1). Both 3D-TOF-MRA (K=0.05) and CE-MRA (K= 0.04) were unable to detect pathological vessel compared to DSA, without difference in accuracy (P= 0.68). For parent artery occlusion detection, agreement with DSA was substantial for 3D-TOF-MRA (K=0.64) and moderate for CE-MRA (K= 0.45), with similar good diagnostic accuracies (P=1).
