临床医学工程 Clinical Medical Engineering 低场强核磁共振STIR(短时间反转恢复 序列)序列对膝关节软骨损伤的诊断价值 刘灵灵 天津北大医疗海洋石油医院放射科 (天津 300450) 文章编号:1006-6586(2021)04-0047-02 中图分类号: 文献标识码:A 内容提要: 目的:对膝关节软骨损伤患者采取低场强核磁共振STIR(短时间反转恢复序列)序列后的诊断结果展开分 析。方法:本次研究选择2018年2月~2020年2月本院收治的80例膝关节外伤患者,所有患者均接受核磁共振 (MRI)检查,分别接受FSE序列检查以及STIR序列检查,结合手术病理检查结果评估两种序列下的诊断效果。 结果:STIR序列检查后准确率更接近。STIR序列检查后漏检率,误诊率,均低于FSE序列,P<。STIR 序列敏感度为(%),高于FSE序列敏感度(%)。结论:对膝关节软骨损伤患者采取低场强核磁共振 STIR序列后可以有效提高诊断准确率,同时可以获得更高的特异度和敏感度,诊断价值显著。 关 键 词: 膝关节 软骨损伤 核磁共振 The Value of Low Field MRI Stir (Short Time Reversal Recovery Sequence) in the Diagnosis of Knee Cartilage Injury LIU Ling-ling Department of Radiology, Tianjin Beida Medical Offshore Oil Hospital (Tianjin 300450) Abstract: Objective: To analyze the diagnosis results of patients with knee articular cartilage injury after taking low field strength magnetic resonance STIR (short time reverse recovery sequence) sequence. Methods: From February 2018 to February 2020, 80 patients with knee joint trauma were selected in this study. All patients were examined by MRI, including FSE s
