| 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AOFAS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。 |

| 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. |
