在这项研究中，我们使用二维双反转恢复黑血序列（BBDI）评估脑囊性动脉瘤（SCAs）的壁。我们检查了14例未破裂性SCA （USCA）患者。BBDI是外周脉冲门控的，在舒张中期获得。我们评估了BBDI是否可以显示动脉瘤壁，并在成像质量可接受的情况下测量了动脉瘤颈部和穹顶部分的壁厚。BBDI显示10例患者的USCA壁，其中4例患者的USCA壁与邻近脑实质或脑脊液的界限不清。动脉瘤平均大小为8.0 mm。10例颈部动脉瘤壁平均厚度为0.60±0.13 mm。5例患者的软骨厚度平均为0.46±0.05 mm。在本研究中，BBDI显示了部分USCA壁，尽管整个USCA壁的空间和对比度分辨率有限。我们认为，该技术可作为评价动脉瘤壁的附加成像工具。
In this study, we evaluated the wall of saccular cerebral aneurysms (SCAs) using two-dimensional double inversion recovery black-blood sequence (BBDI). We examined 14 patients with an unruptured SCA (USCA). The BBDI was peripheral-pulse gated, and was acquired during the mid-diastolic period. We evaluated whether the aneurysmal wall could be visualized with BBDI, and the wall thickness in the neck and dome portion of the aneurysm was measured in cases with acceptable imaging quality. BBDI demonstrated the USCA walls in ten patients in four patients, the USCA walls were poorly delineated from the adjacent brain parenchyma or cerebrospinal fluid. The mean aneurysm size was 8.0 mm. The mean thickness of the aneurysmal wall in the neck portion was 0.60 +/- 0.13 mm in 10 cases. The mean thickness at the domeportion was 0.46 +/- 0.05 mm in five cases. In this study, BBDI revealed some portion of the USCA wall, despite the limited spatial and contrast resolution for delineation of the entire USCA wall. In our opinion, this technique may be used as an additional imaging tool for the evaluation of the aneurysmal wall.
