　　To compare T2* value in healthy and diseased Achilles tendons(AT)using a recently introduced 3D-UTE and analyze the correlation between T2* value and clinical scores.Methods : Fifteen patients and ten volunteers were included in the study and underwent an MR scan with UTE sequence.The T2* value of four regions in Achilles tendons were calculated.An independent sample t-test was used to compare the differences of MRI and clinical score between two groups.Patients were clinically evaluated by the American Orthopaedic Foot and Ankle Society Ankle Hindfoot Scale(AOFAS)and Achilles Tendon Total Rupture Score(ATRS).These values were correlated with the T2* values.Results : The T2* value of four regions were statistically significantly higher in patients than volunteers; In patients,the Pearson correlation coefficient between T2* and AOFAS or ATRS scores were r=0.-0.733 and r=-0.634,respectively.Conclusion : The variability of T2* in healthy and pathologic AT can be quantified by UTE-T2*.It is a promising marker to detect AT tendinopathy in the early stage.T2* value was correlated with ATRS and AOFAS score,which suggests UTE-T2* could give a more precise guidance to clinical outcome.
