We evaluated a time-of-flight three-dimensional MR angiographic sequence with an ultrashort echo time for its ability to characterize the perfusional state of cerebral aneurysms that had been treated with Guglielmi detachable coils and to depict adjacent cerebral arteries. The results were compared with findings at conventional MR angiography and digital subtraction angiography. Adjacent vessels were seen better in 36% of patients imaged with the new technique. Both MR angiographic methods detected residual cerebral aneurysmal perfusion with a tendency to overestimate the patent portion of the aneurysm.
我们评估了一种具有超短回波时间的飞行时间三维磁共振血管造影序列，以确定其对已用 Guglielmi 可脱卸弹簧圈治疗的脑动脉瘤灌注状态进行特征描述以及描绘相邻脑动脉的能力。将结果与传统磁共振血管造影和数字减影血管造影的结果进行比较。在采用新技术成像的患者中，36% 的患者相邻血管显示更佳。两种磁共振血管造影方法均检测到残留的脑动脉瘤灌注，且有高估动脉瘤通畅部分的倾向。
