摘要
目的 采用3D超短回波时间(UTE)-T2*序列比较病变跟腱与健康跟腱T2*值的差异,并分析其与临床评分的相关性.方法 纳入15例跟腱病变患者(病变组)和10名健康志愿者(对照组),行UTE序列及常规序列MR扫描.按纵向长度将跟腱平均分为3段,计算这3段以及跟腱总体的T2*值.采用临床美国足踝外科协会(AOFAS)评分和跟腱完全断裂(ATRS)评分对跟腱病变患者进行临床评估.两组T2*值的比较采用独立样本t检验,患者跟腱T2*值与临床评分的相关性采用Pearson相关分析.结果 病变组患者4个ROI的T2*值明显高于对照组;病变组T2*值与AO-FAS及ATRS评分呈负相关(r=-0.92、-0.90,P＜0.01).结论 跟腱病变患者跟腱T2*值升高,UTE-T2*可从组织生化结构方面定量评估跟腱情况,且与临床一致,有助于跟腱病的早期准确诊断.
Abstract
Objective To compare T2* value in healthy and diseased achilles tendons (AT) using 3D-ultra-short echo time (UTE),and to analyze the correlation between T2* value and clinical scores.Methods Fifteen patients (patients group) and ten volunteers (control group) were included and underwent an MR scan with UTE sequence.The T2* value of four ROI in AT were calculated.Independent sample t-test was used to compare the differences of T2* value between two groups.The correlation of T2* values with the American Orthopaedic Foot and ankle society ankle hindfoot scale (AOFAS) and achilles tendon total rupture score (ATRS) were analyzed.Results The T2* value of four ROI were statistically significantly higher in patients group than those of control group.There were negative correlation between T2* and AOFAS or ATRS scores (r=-0.92,-0.90,both P＜0.01).Conclusion The T2* value of pathologic AT increases.The quantitative MRI UTE-T2* can evaluate AT from the biochemical structure and correlates with clinical outcomes,which is helpful to diagnose AT in the early stage.
