[目的]探讨磁共振成像在血管性眩晕诊断中的应用价值。[方法]选择2010年2月～2011年2月间某院神经内科诊治的血管性眩晕患者98例为观察组,其中男性52例,女性46例,年龄26～86岁,平均57.8岁。另选择96名健康志愿者作为对照组。磁共振设备选择德国西门子MAGNETOMAvanto1.5T超导磁共振扫描仪,头颈联合线圈,行常规颅脑MRI平扫、颅脑3D-TOFMRA及颈部2D-PCMRA。由3位经验丰富的影像诊断医师分别对图像进行分析,主要研究前循环、后循环血管狭窄情况及脑内梗塞灶的情况。[结果]①观察组中有43位患者的MRA图像显示动脉狭窄,占43.87,明显高于对照组(6例,6.25)(P﹤0.05)。观察组中有21例患者的MRI图像显示腔隙性脑梗塞,对照组中未发现脑梗塞。②观察组患者中存在单纯后循环动脉狭窄26例(26.53),明显多于单纯前循环动脉狭窄(9例,9.18)(P﹤0.05)。[结论]磁共振成像可以为血管性眩晕提供有价值的诊断信息,应该作为其常规检查方法。
[Objective] To investigate the value of magnetic resonance imaging in the diagnosis of vascular vertigo. [Methods] A total of 98 patients with vascular vertigo diagnosed and treated in a hospital from February 2010 to February 2011 were selected as the observation group. There were 52 males and 46 females, ranging in age from 26 to 86 years with an average of 57.8 years. Another 96 healthy volunteers were selected as the control group. Magnetic resonance imaging equipment selection Siemens MAGNETOMAvanto1.5T superconducting MRI scanner, co-head and neck coil, routine brain MRI plain scan, brain 3D-TOFMRA and cervical 2D-PCMRA. Three experienced image diagnosticians analyzed the images separately, focusing on the anterior circulation, posterior circulation vascular stenosis and cerebral infarction. [Results] ① MRA images of 43 patients in the observation group showed arterial stenosis (43.87%), which was significantly higher than that of the control group (6 cases, 6.25) (P <0.05). MRI images of 21 patients in the observation group showed lacunar infarction and no cerebral infarction was found in the control group. ② In the observation group, there were 26 cases (26.53) of simple posterior circulation stenosis, which were significantly more than those of simple anterior circulation stenosis (9 cases, 9.18) (P <0.05). [Conclusion] Magnetic resonance imaging can provide valuable diagnostic information for vascular vertigo and should be used as a routine examination method.
