| 目的 观察3.0T 3D高分辨率对比增强MR血管成像(3D HR CE-MRA)显示豆纹动脉(LSA)的可行性。方法 回顾性分析60例因疑诊脑血管疾病而接受头部3.0T 3D HR CE-MRA及数字减影血管造影(DSA)患者,根据年龄将其分为老年组(≥60岁,n=21)和中青年组(＜60岁,n=39)。对3D HR CE-MRA图像进行最大密度投影(MIP)重建,比较3D HR CE-MRA与DSA显示LSA主要分支(直线长度＞5 mm)数目及其长度的差异。结果 3D HR CE-MRA及DSA所示组间双侧LSA主要分支数目之和及LSA长度之和差异均无统计学意义(P均＞0.05)。3D HR CE-MRA与DSA所示左侧LSA及右侧LSA主要分支数目亦均无统计学意义(P均＞0.05);3D HR CE-MRA显示左侧LSA长度及右侧LSA长度均短于DSA。结论 3.0T 3D HR CE-MRA技术可用于显示LSA。 |

| Objective To observe the feasibility of 3.0T 3D high resolution contrast enhanced MR angiography (HR CE-MRA) for displaying lenticulostriate artery (LSA). Methods Data of 60 patients with suspected cerebrovascular diseases who underwent head 3.0T 3D HR CE-MRA and digital subtraction angiography (DSA) were retrospectively analyzed. The patients were divided into elderly group (≥60 years old, n=21) and young/middle-aged group (＜60 years old, n=39). Maximum intensity projection (MIP) reformation was performed based on 3D HR CE-MRA. Then the number of main LSA branches (straight length ＞5 mm) and LSA length showed on 3D HR CE-MRA and DSA were compared. Results There was no significant difference in the total number of bilateral main LSA branches and the length of bilateral LSA showed on 3D HR CE-MRA and DSA between groups (all P＞0.05). No significant difference was found in the number of left (4.0 branches vs.3.5 branches) or right (4.0 branches vs.3.5 branches) main LSA branches showed betwcen 3D HR CE-MRA and DSA (both P＞0.05). The length of LSA on the left ( mm) and the right side ( mm) showed on 3D HR CE-MRA were both shorter than those showed on DSA ( mm, mm, t=－15.559, -12.161, both P＜0.001). Conclusion 3.0T 3D HR CE-MRA was feasible for displaying LSA. |
