目的为了进一步提高临床对膝关节软骨损伤确诊率,分析和探讨MR不同成像序列在临床应用中的价值和意义。方法遵照随机双盲对照的原则抽取2015年1月至2015年12月期间来我院就诊的443例考虑膝关节软骨损伤的患者作为研究对象,所有入组的患者均常规给予SD-FS-SPGR(矢状三维抑脂扰相梯度回波序列)和FS-FSE-T2W(脂肪抑制快速自旋回波T2W1序列)检查并根据Oter bridge分级标准实施分析,最后所有患者均采取关节镜检查,比较两组检查方案的分级情况。结果经过研究发现,SD-FS-SPGR和FS-FSE-T2W在诊断各级膝关节软骨损伤过程中与膝关节镜检查结果完全一致率分别为82.6%、70.0%,且SD-FS-SPGR在检测Ⅱ度及以下膝关节软骨损伤的敏感性及特异性分别为94.0%、95.6%,与膝关节镜检查结果一致率为88%。结论临床上在诊断膝关节软骨损伤的过程中应用MR不同成像序列,其准确性基本等同于关节镜,而且由于FS-FSE-T2W对Ⅱ度以下膝关节软骨损伤确诊率较高,因此可以广泛用于膝关节软骨损伤。
Objective To further improve the clinical diagnosis of knee joint cartilage injury, analysis and explore the different MR imaging sequences in the clinical application of value and significance. Methods According to the principle of randomized double-blind control, 443 patients with knee joint cartilage injury treated in our hospital from January 2015 to December 2015 were selected as the study subjects. All patients were routinely given SD-FS-SPGR (Sagittal three-dimensional fat suppression scrambling gradient echo sequence) and FS-FSE-T2W (fat suppression fast spin echo T2W1 sequence) and analyzed according to the Oter bridge grading standard analysis, and finally all patients were taken arthroscopy, comparing two Group check the grading of the program. Results The results of knee arthroscopy showed that SD-FS-SPGR and FS-FSE-T2W were 82.6% and 70.0% identical to those of knee arthroscopy in diagnosis of all kinds of knee cartilage injuries respectively The sensitivity and specificity for the detection of cartilage injury in the second degree and below were 94.0% and 95.6%, respectively, which was consistent with the results of knee arthroscopy examination (88%). Conclusions The clinical application of MR imaging sequences in the diagnosis of knee cartilage injury is almost equivalent to the accuracy of arthroscopy. FS-FSE-T2W can be widely used in the diagnosis of knee cartilage injury below grade II For knee cartilage injury.
