中文摘要:目的 评价时间飞跃法磁共振血管成像技术(3.0T TOF-MRA)在颅内动脉瘤弹簧圈栓塞术后随访中的应用价值。方法 对48例在笔者医院行颅内动脉瘤弹簧圈栓塞术后1~2年的患者进行影像学随访,均行3.0T TOF-MRA及数字减影血管造影(DSA)检查。以DSA结果为金标准,对MRA的影像质量及结果进行比较分析。结果 3.0T TOF-MRA对判断动脉瘤复发的敏感度为85.7%,特异性为95.7%,总准确率为93.8%;对判断载瘤动脉通畅性的准确率为93.8%,两种方法之间比较,差异无统计学意义(P>0.05)。结论 3.0T TOF-MRA在判断弹簧圈栓塞术后患者动脉瘤栓塞效果及载瘤动脉通畅性上,与DSA结果比较有高度的一致性,可作为颅内动脉瘤弹簧圈栓塞术后随访的常规手段。适当调整扫描参数可获得更优质的图像,以提高诊断准确率。对于MRA阳性及不确定性结果应个体化分析,必要时行DSA检查。 |

Abstract:Objective To evaluate the application of 3.0T TOF magnetic resonance angiography (MRA) in intracranial aneurysm coiling follow-up retrospectively. Methods In our hospital,48 patients who underwent intracranial aneurysm coiling were followed up for one to two years with radiologic examination, which inclouded 3.0T TOF-MRA and Digital subtraction angiography(DSA)examination. DSA served as the golden standard. The MRA image quality and the results were compared. Results 3.0T TOF-MRA to determine aneurysm recurrence sensitivity was 85.7%, specificity was 95.7%,total accuracy rate was 93.8%,and the accuracy of the patency of the parent arterial was 93.8%. There was no significant difference between the 3.0T TOF-MRA and DSA (P>0.05). Conclusion In the patients after coiling, 3.0T TOF-MRA in the judgment of the aneurysm embolization results and the patency of the parent artery had a high degree of consistency compare with DSA. We can use 3.0T TOF-MRA as a routine means in the follow-up. We should analysis individually for positive results and uncertainties. By optimizing imaging and scanning parameters might obtain better images. Perform DSA if necessary,when MRA was positive or uncertainty. |
