摘　　要：本文旨在探讨3D LAVA-FLEX序列在喉癌和下咽癌MR增强扫描中的应用价值。对40例临床确诊的喉癌和下咽癌患者行MRI增强扫描,分别采用2D IDEAL T1WI序列和3D LAVA-FLEX序列,对两种方法所得图像进行分析和评价。结果显示,所有患者均完成IDEAL T1WI和3D LAVA-FLEX序列增强检查。在运动伪影和流动伪影控制方面,3D LAVA-FLEX比IDEAL T1WI序列效果更好,差异有统计学意义(P<0.001);肿瘤显示效果方面,3D LAVA-FLEX与IDEAL T1WI序列差异没有统计学意义,两者均具有良好的显示效果。结果表明3D LAVA-FLEX序列可以为头颈部肿瘤增强扫描提供满意的图像质量,且扫描时间更断。This article aims to explore the application value of 3D LAVA-FLEX sequence in enhanced MR scanning of laryngeal carcinoma and hypopharyngeal carcinoma.There were 40 patients who were clinically diagnosed laryngeal cancer and hypopharyngeal cancer.They were performed enhanced MRI scans to analyze and evaluate the images obtained by the two methods,using 2D IDEAL T1WI sequence and 3D LAVA-FLEX sequence,respectively.The results showed that all patients completed IDEAL T1WI and 3D LAVA-FLEX sequence enhancement examination.3D LAVA-FLEX was better than IDEAL T1WI sequence in terms of motion artifact and flow artifact control(P<0.001).The difference of tumor display effect between 3D LAVA-FLEX and IDEAL T1WI is not statistically significant.The two sequences both have good display effects.It is concluded that the 3D LAVA-FLEX sequence can provide satisfactory image quality and less scanning time for enhanced scanning of head and neck tumors.
