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 samplet-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, bothP<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.
