| 目的 观察MR三维颅内血管解剖成像(3D-IVAS)技术显示大脑中动脉(MCA)的价值。方法 回顾性分析137例接受3D-IVAS及三维时间飞跃法MR血管成像(3D-TOF MRA)检查的患者，共纳入274支MCA，包括动脉粥样硬化组197支、动脉粥样硬化性烟雾综合征组23支、烟雾病组8支及正常组46支；对比3D-IVAS、3D-TOF MRA显示MCA效果评分，于3D-IVAS图像上测量各组MCA起始部血管外径，并进行比较。结果 3D-IVAS显示MCA的效果评分小于3D-TOF MRA(P<0.01)。动脉粥样硬化组、动脉粥样硬化性烟雾综合征组、烟雾病组及正常组MCA外径分别为(2.87±0.56)、(1.99±0.50)、(1.97±0.74)及(2.75±0.43)mm，组间总体差异有统计学意义(F=24.16，P<0.01)，且动脉粥样硬化性烟雾综合征组、烟雾病组均小于正常组及动脉粥样硬化组(P均<0.05)。结论 利用3D-IVAS技术可清晰显示大脑中动脉外廓，有助于鉴别诊断相关疾病。 |

| Objective To observe the value of MR three-dimensional intracranial vascular anatomical scanning (3D-IVAS) for displaying middle cerebral artery (MCA). Methods Data of 137 patients who underwent 3D-IVAS and 3D-time of flight MR angiography (3D-TOF MRA) were retrospectively analyzed. A total of 274 MCA were enrolled, including 197 in atherosclerotic group, 23 in atherosclerotic moyamoya syndrome group, 8 in moyamoya disease group and 46 in normal group. The visibility of MCA on 3D-IVAS and 3D-TOF MRA were scored and compared. The outer diameter of MCA was quantified in the proximal portion on 3D-IVAS images. Results The scores of MCA on 3D-IVAS images were less than that on 3D-TOF MRA (P<0.01). The outer diameters of MCA in atherosclerotic group, atherosclerotic moyamoya syndrome group, moyamoya disease group and normal group was (2.87±0.56)mm, (1.99±0.50)mm, (1.97±0.74)mm and (2.75±0.43)mm, respectively, being overall significantly different among 4 groups (F=24.16, P<0.01), while in atherosclerotic moyamoya syndrome and moyamoya disease groups were both lower than in atherosclerotic and normal groups (all P<0.05). Conclusion 3D-IVAS technique could clearly display the outer contour of middle cerebral artery, hence being helpful for differential diagnosis of relative diseases. |
