我们的目的是比较常规和运动致敏驱动平衡准备的对比后3D T1加权TSE序列（通过使用不同翻转角演变，SPACE，应用优化对比的采样完美性）之间未破裂颅内动脉瘤中动脉瘤壁增强的可检测性。在3 T下扫描了22例患者的30个未破裂颅内动脉瘤。与运动敏感驱动平衡准备SPACE序列相比，使用常规序列检测到的动脉瘤壁增强更显著（10/30 vs. 2/30，P < .0001）。对比度噪声比的测量结果在常规和运动敏感驱动平衡准备序列之间没有差异（P = .51）。流动的血液可以模拟血管壁增强使用传统的空间序列与病人护理的潜在影响。
Our aim was to compare the detectability of aneurysmal wall enhancement in unruptured intracranial aneurysms between conventional and motion-sensitized driven equilibrium-prepared postcontrast 3D T1-weighted TSE sequences (sampling perfection with applicationoptimized contrasts by using different flip angle evolution, SPACE). Twenty-two patients with 30 unruptured intracranial aneurysms were scanned at 3T. Aneurysmal wall enhancement was more significantly detected using conventional compared with motion-sensitized driven equilibrium-prepared SPACE sequences (10/30 versus 2/30, P < .0001). Contrast-to-noise ratio measurements did not differ between conventional and motion-sensitized driven equilibrium-prepared sequences (P = .51). Flowing blood can mimic aneurysmal wall enhancement using conventional SPACE sequences with potential implications for patient care.
