摘　　要：目的应用三维快速自旋回波T2WI(T2WI-3D-TSE)技术观察颈性眩晕(CV)患者迷路动脉形态特点,分析其在CV发病中的作用.方法同时选择53例CV患者及20例正常对照作为研究对象,行T2WI-3D-TSE检查,分析并观察2组间迷路动脉走行特点,并作统计分析.结果迷路动脉形态可分为:Ⅰ型血管正常显影、Ⅱ型血管纤细且信号明显减低、Ⅲ型血管迂曲、Ⅳ血管不显影,其中血管异常率为62.26%.Ⅱ型血管纤细与Ⅲ型血管迂曲在2组间存在统计学差异(均P<0.05).结论T2WI-3D-TSE技术能够准确直观地显示出迷路动脉形态特点;迷路动脉血管形态异常是CV发病的重要基础,并可加速其发病.Objective To observe the morphological characteristics of labyrinthine artery in patients with cervical vertigo(CV)by three dimensional fast spin echo T2WI(T2WI-3D-TSE)technique and evaluate its role in the pathogenesis of CV.Methods A total of 53 patients with CV and 20 normal controls were recruited and scanned with T2WI-3D-TSE technique.The morphological characteristics was evaluated and compared between the two groups.Results The morphology of labyrinthine artery was divided into four types as follows:type Ⅰ normal vessel,type Ⅱ slender vessel with significant signal reduction,type Ⅲ tortuous vessel,type Ⅳ dysplastic vessel.The heteromorphosis of labyrinthine artery was 62.26%.The morphology of type Ⅱ and type Ⅲ showed significant difference between the two groups(PV0.05).Conclusion T2WI-3D-TSE technique can accurately and intuitively display the morphological characteristics of labyrinthine artery.The abnormal morphology of labyrinthine artery is an important basis for the onset of CV,and accelerates the pace of its onset.
