Abstract

Objective To evaluate the preliminary application of three dimensional T1-weighted sampling perfection with application-optimized contrasts by using different flip angle evolutions (3D T1-SPACE) combined with three dimensional time-of-flight magnetic resonance angiography (3D-TOF MRA) in the follow-up for the intracranial aneurysm treated with Pipeline Flex embolization device (FD). Methods A total of 20 patients with 25 intracranial aneurysms were treated with Pipeline Flex embolization at the Department of Cerebrovascular Intervention, People′s Hospital of Zhengzhou University, Henan Provincial People′s Hospital from September 2018 to April 2019 and were prospectively enrolled. All patients were followed up with 3.0T 3D T1-SPACE sequence, 3D-TOF MRA and digital subtraction angiography (DSA) examination. O′kelly-Marotta (OKM) grading scale was used to evaluate the aneurysm residual and the four-point scale was used to evaluate the in-stent lumen visibility. Results The follow-up period for all patients was 6.0±0.8 months (range: 4-7 months). The OKM scale of all aneurysms evaluated by DSA indicated 18 patients with grade D, 2 patients with grade C and 5 patients with grade B. For aneurysms evaluated by 3D-TOF MRA combined with source image, the results showed grade D in 19 patients, C in 2 and B in 4. The overall concordance rate between 3D-TOF MRA and DSA was 88.0% (22/25). Taking DSA as standard(grade 4), the four-point scale of in-stent lumen of all 20 patients treated with 23 Pipeline Flex embolization devices and evaluated by 3D-TOF MRA indicated grade 3 in 16 stents, 2 in 6 and 1 in 1. No one showed the same as DSA results. However, grade 4 was revealed in 21 stents and 3 in 2 based on the evaluation by 3D T1-SPACE. The total concordance rate of 3D T1-SPACE and DSA was 91.3% (21/23). Conclusions Preliminary observations show that compared with DSA, 3D-TOF MRA could better assess the aneurysmal occlusion after FD treatment of intracranial aneurysms. The 3D T1-SPACE sequence shows the in-stent lumen clearly. The combination of the two sequences can be used for follow-up after FD treatment of intracranial aneurysms.

3D T1-SPACE联合3D- tof MRA在Pipeline Flex栓塞装置治疗颅内动脉瘤随访中的初步研究

目的评价不同翻转角度演变（3DT1-SPACE）结合三维飞行时间磁共振血管成像（3D-TOF-MRA）在应用Pipeline Flex栓塞装置（FD）治疗颅内动脉瘤随访中应用优化对比度的三维T1加权采样完美性的初步应用。方法自2018年9月至2019年4月，在河南省郑州大学人民医院脑血管介入科对20例25个颅内动脉瘤患者进行管道柔性栓塞治疗。所有患者均进行3.0T三维T1-SPACE序列、3D-TOF MRA和数字减影血管造影术（DSA）检查。采用O’kelly-Marotta（OKM）分级量表评价动脉瘤残余，采用四点量表评价支架内管腔能见度。结果所有患者的随访时间为6.0±0.8个月（范围：4-7个月）。DSA评估的所有动脉瘤的OKM评分显示D级18例，C级2例，B级5例。3D-TOF MRA结合源图像评估的动脉瘤，结果显示D级19例，C 2例和B 4例。3D-TOF MRA与DSA的总符合率为88.0%（22/25）。以DSA为标准（4级），使用23个Pipeline Flex栓塞装置并通过3D-TOF MRA评估的所有20名患者的支架内管腔四点量表显示，16个支架为3级，6个支架为2级，1个支架为1级。没有人显示出与DSA相同的结果。然而，根据3D T1-SPACE的评估，21个支架显示4级，2个支架显示3级。3DT1-SPACE与DSA的总符合率为91.3%（21/23）。结论与DSA相比，3D-TOF MRA能更好地评估FD治疗颅内动脉瘤后的动脉瘤闭塞情况。3D T1-SPACE序列清楚地显示了支架内管腔。两种序列的组合可用于颅内动脉瘤FD治疗后的随访。关键词：颅内动脉瘤；磁共振成像；随访研究；分流器装置
