囊状脑动脉瘤的瘤壁增强还没有得到充分的研究。本研究的目的是探讨钆注射后三维快速自旋回波序列运动敏感驱动平衡成像（<$DE-3D-TSE）中动脉瘤壁增强的发生率。我们回顾性分析了2011年9月至2013年7月期间117例颅内动脉瘤患者的增强前后<$DE-3D-TSE图像。本研究共纳入61例蛛网膜下腔出血（SAH）患者和56例非SAH患者的61例破裂动脉瘤和83例未破裂动脉瘤。我们评价了每个动脉瘤在增强后的MSDE-3D-TSE图像上与增强前图像相比的壁增强。我们将动脉瘤壁强化分为三组：“强强化”、“弱强化”和“无强化”。73.8/24.6%的破裂动脉瘤和4.8/13.3%的未破裂动脉瘤检测到动脉瘤的“强/弱增强”。1.6%的破裂动脉瘤和81.9%的未破裂动脉瘤出现“无强化”，而在MSDE-3D-TSE序列的血管壁成像中，破裂动脉瘤的血管壁常出现强化。因此，蛛网膜下腔室壁增强可能是破裂情况的一个指标，这是管理SAH患者的有用信息。
Wall enhancement of saccular cerebral aneurysms has not been researched sufficiently. Our purpose of this study was to investigate the incidence of aneurysmal wall enhancement by the three-dimensional turbo spin-echo sequence with motion-sensitized driven equilibrium (MSDE-3D-TSE) imaging after gadolinium injection.We retrospectively reviewed the pre- and postcontrast MSDE-3D-TSE images of 117 consecutive patients with intracranial aneurysms from September 2011 to July 2013. A total of 61 ruptured and 83 unruptured aneurysms of 61 patients with subarachnoid hemorrhage (SAH) and 56 non-SAH patients were enrolled in this study. We evaluated the wall enhancement of each aneurysm on postcontrast MSDE-3D-TSE images compared with precontrast images. We classified the aneurysmal wall enhancement into three groups as "Strong enhancement," "Faint enhancement," and "No enhancement.""Strong/Faint enhancement" of the aneurysm was detected in 73.8/24.6 % of the ruptured aneurysms and 4.8/13.3 % of the unruptured aneurysms. "No enhancement" was found in 1.6 % of the ruptured aneurysms and 81.9 % of the unruptured aneurysms.By magnetic resonance vessel wall imaging using the MSDE-3D-TSE sequence, wall enhancement was frequently observed on ruptured aneurysms. Therefore, aneurysmal wall enhancement may be an indicator of the ruptured condition, which is useful information for managing patients with SAH.
