摘要 目的:分析研究椎-基底动脉迂曲扩张症(VBD)的MRI诊断及其临床应用价值。方法:分析于2016年6月—2018年10月期间,12例椎-基底动脉迂曲扩张症(VBD)的MRI平扫及MRA的图像,分析其血管的异常分布、血管形态的改变以及MR信号强度的变化。结果:12例在MRI上表现为椎-基底动脉迂曲扩张,其中10例同时累及椎基底动脉及颈内动脉。基底动脉扩张后的直径约5.0mm~14.5mm,延长的长度约为30.4mm~33.6mm。另外,12例病例中,4例迂曲的血管走行以上下方向折曲,8例为左右方向的扭曲延长。11例患者的MRI平扫中可发现梗死灶,梗死灶多发于后循环。结论:MRI及MRA有利于诊断椎-基底动脉迂曲扩张症(VBD),并对该症进行综合评价,为临床提供有力依据,可作为首选检查。
