To evaluate the usefulness of the "Motion Correction" function of the dual volume-3D-volume-rendering technique (DV-3D-VRT) in follow-up digital subtraction angiography (DSA) of intracranial coiled aneurysms.
This study used data collected from consecutive, follow-up DSAs after the coiling of 64 intracranial aneurysms in 59 patients. We performed subtracted 3D-rotational angiographies (3D-RAs) on all DSAs and obtained DV-3D-VRT images. We then assessed recurrence using DV-3D-VRT images with and without the motion correction functions (MC(+) vs. MC(-)) and observed which method showed better agreement with the reference assessment (using a combination of 2D DSA and TOF MRA images).
The recurrence of MC(-) DV-3D-VRT images showed 51.6% (33/64) agreement with the reference assessment, whereas the MC(+) DV-3D-VRT images showed 78.1% (50/64) (P = 0.035, McNemar test).
Motion correction is a useful complementary imaging technique in evaluating aneurysm recurrence after endovascular embolization. MC(+) DV-3D-VRT image showed higher inter-observer agreement than MC(-) DV-3D-VRT.
评估双容积-3D 容积再现技术（DV-3D-VRT）中“运动校正”功能在颅内螺旋圈动脉瘤数字减影血管造影（DSA）随访中的作用。
本研究使用了 59 名患者 64 个颅内动脉瘤弹簧圈治疗后连续随访 DSA 采集的数据。我们对所有 DSA 进行了减影 3D-旋转血管造影（3D-RA），并获得了 DV-3D-VRT 图像。然后，我们使用带有和不带有运动校正功能（MC(+)和 MC(-)）的 DV-3D-VRT 图像评估复发情况，并观察哪种方法与参考评估（结合 2D DSA 和 TOF MRA 图像）具有更好的一致性。
MC(-)DV-3D-VRT 图像的复发显示与参考评估有 51.6%（33/64）的一致性，而 MC(+)DV-3D-VRT 图像则显示有 78.1%（50/64）的一致性（P=0.035，McNemar 检验）。
运动校正技术是评估血管内栓塞后动脉瘤复发的一种有用的补充成像技术。MC(+)DV-3D-VRT 图像的观察者间一致性高于 MC(-)DV-3D-VRT 图像。
