Summary:目的探讨三维T2可变翻转角加权快速自旋回波成像技术（three dimensional-T2 weighted imagingsampling perfection with application optimized contrasts using different flip angle evolutions,3D-T2WISPACE）序列在颈动脉高分辨率磁共振成像中的应用价值。方法收集临床怀疑颈动脉病变患者30例,进行高分辨多对比颈动脉磁共振成像（magnetic resonance imaging,MRI）,行冠状位3D-T2WI-SPACE序列并应用3D后处理软件进行斜矢状位和轴位重建。比较3D-T2WI-SPACE序列和横轴位黑血T2WI序列的信噪比及图像质量,并对图像成像范围、对病变诊断信息提供的充分程度进行比较。结果 60支颈动脉中,正常13支,病变47支。其中颈动脉粥样硬化病变44支,颈动脉夹层1支,不明原因的特发性狭窄2支。30例病例图像质量评价中,3D-T2WI-SPACE序列图像质量2级5例,3级25例;T2WI序列图像质量2级4例,3级26例。3D-T2WI-SPACE序列对诊断信息提供的充分程度略优于高分辨T2WI。3D-T2WI-SPACE序列与高分辨率T2WI图像的覆盖范围分别为（114.7±22.4）mm和46 mm。3D-T2WI-SPACE序列图像与高分辨T2WI的信噪比平均值分别为15.7±3.5及22.7±14.7,差异无显著性（P=0.163）。结论 3D-T2WI-SPACE技术可作为颈动脉高分辨成像序列中的必要辅助序列。应用3D-T2WI-SPACE序列结合重建技术,可为临床诊断提供更多信息。

Objective To study the application value of three dimensional-T2 weighted imaging-sampling perfection with application optimized contrasts using different flip angle evolutions （3D-T2WI-SPACE） sequence in carotid high-resolution magnetic resonance imaging （MRI）. Methods Thirty patients with suspected carotid disease were recruited in this study. High-resolution multicontrast MRI was performed using 3.0T MRI with a 4-channel surface carotid coil. 3D-T2WI-SPACE sequence was applied by coronal plane; and oblique saggital and axial images were reconstructed using post-processing software. Signal-to-noise ratio, image quality of 3D-T2WI-SPACE sequence and axial high-resolution T2WI sequence, as well as scan coverage and diagnostic information were compared. Results Among all sixty carotids, thirteen vessels are normal, and forty-four carotids were found plaques; one was carotid dissection;
