【摘要】：目的:通过比较低场磁共振FIR-STIR、Fat Sep G-WFT2*两种脂肪抑制序列与FSE-T2WI成像评价髌内侧支持带的损伤,为临床诊断提供最优序列方法。方法:对临床查体怀疑有髌内侧支持带损伤的急性膝关节损伤49例患者行低场磁共振常规扫描后,加做FIR-STIR、Fat Sep G-WFT2*和FSE-T2WI三种序列轴位扫描。通过三种序列对膝关节髌内侧支持带损伤分级评判结果与手术或/和关节镜诊断分级进行对比,评价分析三种扫描序列对诊断膝关节髌内侧支持带损伤的可行性,找出最佳诊断序列。结果:49例患者中,髌内侧支持带正常者5例,髌内侧支持带损伤Ⅰ级者7例,髌内侧支持带损伤II级者22例,髌内侧支持带损伤Ⅲ级者15例。FIR-STIR序列、FSE-T2WI序列和Fat Sep G-WFT2*序列髌内侧支持带损伤分级评判结果与手术或/和关节镜分级比较,其敏感度分别为93.2%、90.9%和97.7%;特异度分别为62.5%、55.6%和83.0%;准确度分别为93.9%、91.8%和97.9%。FIR-STIR序列、FSE-T2WI序列和Fat Sep G-WFT2*序列等三种序列的Kappa值分别为0.941、0.800、0.856,均0.750。三种序列横轴位在显示髌内侧支持带损伤分级与手术或/和关节镜诊断分级方面有较好的一致性,其中以Fat Sep G-WFT2*序列与手术或/和关节镜诊断的一致性更好。结论:1.FIR-STIR序列、FSE-T2WI序列和FatSepG-WFT2*序列横轴位扫描在显示髌内侧支持带损伤分级与手术或/和关节镜诊断分级方面有较好的一致性。2.Fat Sep G-WFT2*序列显示髌内侧支持带损伤的效果较FIR-STIR序列、FSE-T2WI序列敏感度、特异度、准确度更高,可以在膝关节损伤中作为常规序列来使用。
[Abstract]:Objective: To compare the low field magnetic resonance FIR-STIR, Fat Sep G-WFT2* two and FSE-T2WI fat suppression sequence imaging evaluation of medial patellar retinaculum injury, to provide the optimal sequence method for clinical diagnosis. Methods: the clinical examination of suspected patella medial support of acute knee joint injury with 49 cases of patients with low field MRI routine after scanning, with FIR-STIR Fat, Sep G-WFT2* and FSE-T2WI three series axial scanning. By three sequences of knee joint medial patellar retinaculum injury classification and surgical results of arthroscopy or / and diagnostic classification comparison, evaluation analysis on three kinds of sequences in the diagnosis of knee joint patellar medial support feasibility with damage. To find the best diagnostic sequence. Results: in 49 cases, 5 cases of medial patellar retinaculum were normal, 7 cases with injury of medial patellar support in grade I, 22 cases with injury of medial patellar support II, medial patellar support belt injury Grade III in 15 cases with.FIR-STIR sequence, FSE-T2WI sequence and Fat sequence Sep G-WFT2* medial patellar retinaculum injury classification and surgical results of arthroscopy or / and grading, the sensitivity were 93.2%, 90.9% and 97.7%; the specificity was 62.5%, 55.6% and 83% respectively; the accuracy was 93.9%, 91.8% and 97.9%.FIR-STIR sequence. FSE-T2WI Fat Sep sequence and G-WFT2* sequence of three sequences Kappa = 0.941,0.800,0.856, 0.750. three series of axial in medial patellar retinaculum injury grading and surgical or / and arthroscopic diagnosis and classification has a good consistent, with better consistency Fat Sep G-WFT2* sequence with surgery or / and arthroscopy diagnosis. Conclusion: 1.FIR-STIR sequence, FSE-T2WI sequence and FatSepG-WFT2* sequence in the axial scan showed medial patellar retinaculum injury grading and surgical or / and arthroscopic diagnosis grading have Good consistency..2.Fat Sep G-WFT2* sequence shows that the effect of patellar medial retinaculum injury is higher than FIR-STIR sequence, FSE-T2WI sequence sensitivity, specificity and accuracy. It can be used as a routine sequence in knee injury.
