Purpose

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.

Materials and methods

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.

Results

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).

Conclusion

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.

用于Web设备管理的CS-TOF和CTA / DSA之间的比较

目的

尚未对三维压缩感测飞行时间MR血管造影（3D-CS-TOF）在WEB设备管理中的作用进行研究。我们评估了3 tesla 3D-CS-TOF在WEB设备植入的管理和随访中的功效。

材料和方法

回顾性检查了使用WEB装置治疗的69例患者的73个动脉瘤。在3D-CS-TOF，CTA和DSA图像上评估并比较了动脉瘤的形态学参数和栓塞结果。

结果

分别在61（83.6％），7（9.6％）和5（6.8％）的动脉瘤中观察到阻塞，颈部残留和复发性动脉瘤。与动脉瘤大小测量相关的阅读器间和阅读器内一致性值是完美的。在3D-CS-TOF图像上，动脉瘤的大小，年龄和近端曲折度与动脉瘤和亲代血管的可见度呈负相关（分别为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（分别为p = 0.031; p = 0.005）。3D-CS-TOF结果与DSA或CT血管造影（CTA）结果完全吻合（p <0.001）。

结论

根据我们的结果，3D-CS-TOF可以是WEB辅助栓塞的管理或后续操作的简便，快速和可靠的替代方案。
