【摘要】 目的:采用连续2D TOF法MRA无创成像技术探讨椎动脉病变的MRA表现及其临床应用价值.方法:对350例椎动脉病变病人和50例正常人分别进行磁共振血管成像,并对检查结果进行分析研究.结果:把正常人椎动脉平均分三段测量直径,得到MRA椎动脉正常值,左侧(4.1±0.79)mm,右侧(3.2±0.83)mm.350例椎动脉病变病人中,椎动脉扭曲26例,椎动脉狭窄320例(其中轻度狭窄85例,中度狭窄147例,重度狭窄88例),椎动脉完全闭塞4例.结论:MRA是椎动脉病变的重要检查方法,对本病的诊断、分型、治疗方法的选择和预后判断具有重要价值.更多还原

【Abstract】 Objective:To study the image features of vertebrarterial lesions in MR angiography(MRA) via atraumatic continuous 2D time of flight(TOF) MRA for 350 patients with vertebrarterial lesions and 50 healthy adults.Results:The diameters of each section in three equal parts of vertebral artery were measured and the normal values of its diameter(left side:4.1±0.79mm;riht side:3.2±0.83mm) were obtained.Among 350 patients 26 cases of vertebrarterial twist,320 cases of vertebral artery stenosis(including 85 cases of mild stenosis,147 cases of medium ones and 88 cases of severe ones) and 4 cases of vertebral artery occlusion were diagnosed confirmatively.Conclusion:This method plays an important role in the diagnosis,typing,selecting therapeutic method and judging the prognosis of vertebrarterial lesions.更多还原
