目的：分析磁共振GRE-T2*序列在膝关节半月板撕裂成像中的诊断价值。方法收集我院2012年01月-2014年06月收治的310例膝关节半月板撕裂患者的临床资料，所有患者均接受1.5T超导磁共振扫描仪作矢状位FSE-T2WI-FS、GRE-T2*、FSE-PDWI-FS及FSE-T1WI序列扫描，比较不同序列扫描在诊断膝关节半月板撕裂中的应用价值。结果 GRE-T2*序列，膝关节半月板损伤清晰评级2级297例，图像清晰显示率占95.81%，与其他三种序列图像质量对比差异有统计学意义(P<0.05)；GRE-T2*序列共检出膝关节半月板撕裂损伤309例，检出率为99.68%；与其他三种序列检出率对比差异有统计学意义(P<0.05)。结论在膝关节半月板撕裂损伤的临床诊断中，应用MRI扰相GRE-T2*序列，可清晰显示患者膝关节半月板撕裂损伤的结构类型，提高半月板病变的检出率，可作为膝关节MRI检查的常规序列。

Objective To analyze the diagnostic value of magnetic resonance GRE-T2* sequence in knee meniscus tear.Methods The clinical datum of 310 patients with knee joint meniscus tear admitted into the hospital from January 2012 to June 2014 were collected. All patients received FSE-T2WI-FS, GRE-T2*, FSE-PDWI-FS and FSE-T1WI sequence scanning of 1.5T superconducting magnetic resonance scanner sagittal view. The application value of different sequences scanning in the diagnosis of knee meniscus tear was compared.Results GRE-T2* sequence, there were 297 cases with class 2 in clarity rating of knee meniscus tear and clear image display accounted for 95.81%. Compared with the image quality of other three kinds of sequence, the difference was statistically significant (P<0.05); There were 309 cases with knee meniscus tear detected by GRE-T2* sequence in total and the detection rate was 99.68%; Compared with that of the other three sequences, the difference was statistically significant (P<0.05).Conclusion In the clinical diagnosis of knee meniscus tear, to adopt MRI to spoiled GRE-T2* sequence can clearly show the structure type of knee meniscus tear and improve the detection rate of meniscus lesions and can be taken as the conventional sequence for MRI detection of knees.
