There is no study on the role of three-dimensional compressed sensing time of flight MR angiography (3D-CS-TOF) in the management of the WEB device. We evaluated the efficacy of 3-tesla 3D-CS-TOF for the management and follow-up of the WEB device implantations.
Seventy-three aneurysms of 69 patients treated with the WEB device were retrospectively examined. Morphological parameters and embolization results of the aneurysms were assessed and compared on 3D-CS-TOF, CTA, and DSA images.
Occluded, neck remnant, and recurrent aneurysms were observed in 61 (83.6%), 7 (9.6%), and 5 (6.8%) aneurysms, respectively. Inter- and intra-reader agreement values related to aneurysm size measurements were perfect. Aneurysms size, age, and proximal vessel tortuosity were negatively correlated with the visibility of the aneurysms and parent vessels on 3D-CS-TOF images (p = 0.043; p = 0.032; p < 0.001, respectively). Subarachnoid hemorrhage and age are associated with 3D-CS-TOF artifacts (p = 0.031; p = 0.005, respectively). 3D-CS-TOF findings are in perfect agreement with DSA or CT angiography (CTA) results (p < 0.001).
According to our results, 3D-CS-TOF can be an easy, fast, and reliable alternative for the management or follow-up of WEB assisted embolization.
目前尚无研究探讨三维压缩感测时间飞跃磁共振血管成像（3D-CS-TOF）在 WEB 装置管理中的作用。我们评估了 3T 三维 CS-TOF 在 WEB 装置植入物的管理和随访中的效果。
回顾性分析 69 例 73 个接受 WEB 装置治疗的动脉瘤患者的资料。评估并比较了 3D-CS-TOF、CTA 和 DSA 图像上动脉瘤的形态学参数和栓塞结果。
61 个（83.6%）、7 个（9.6%）和 5 个（6.8%）动脉瘤分别为闭塞、颈部残留和复发动脉瘤。与动脉瘤大小测量相关的读者间和读者内一致性值均为极好。动脉瘤大小、年龄和近端血管迂曲与 3D-CS-TOF 图像上动脉瘤和载瘤动脉的显示程度呈负相关（p=0.043；p=0.032；p<0.001）。蛛网膜下腔出血和年龄与 3D-CS-TOF 伪影相关（p=0.031；p=0.005）。3D-CS-TOF 结果与 DSA 或 CTA 结果完全一致（p<0.001）。
根据我们的结果，3D-CS-TOF 可为 WEB 辅助栓塞的管理或随访提供一种简便、快速且可靠的替代方法。
