低场梯度回波序列在诊断椎体挫伤中的临床价值 (pdf)[摘要] 目的 讨论低场梯度回波序列在椎体挫伤诊断中的价值。方法 58例椎体挫伤患者，常规T1WI、T2WI、IRS序列，90°翻转角梯度回波(GRL)序列，对比分析。 结果 常规T1WI、T2WI在58例椎体挫伤患者中共发现74处椎体挫伤，IRS序列发现113处，90°翻转角梯度序列T*1WI共发现122处。 结论 90°翻转角梯度回波(GRL)序列较常规快速自旋回波序列T1WI、T2WI更加敏感，对椎体挫伤诊断具有较高的临床应用价值。

[Abstract] Objective To discuss the clinical value of the sequence of downfield gradient recalled echo in diagnosing contusion of vertebrae body. Methods Contrast analysis for 58 patients with contusion of vertebrae body by conventional T1WI,T2WI,IRS sequence and 90° turns the corner gradient recalled echo(GRL)sequence. Results In the 58 examples,74 contusion of vertebrae body was discovered by conventional T1WI,T2WI;113 contusion of vertebrae body was also found by the IRS sequence and 122 contusion of vertebrae body was discovered by 90° turn the corner gradient sequence with T*1WI imagery altogether. Conclusion The sequence of 90° turns the corner gradient echo(GRL)to compare with the conventional fast spinning echo sequence T1WI,T2WI is more sensitive,has the higher clinical practice value to the diagnosising contusion of vertebrae body. ......
