[Abstract] Objective: To study the initial application of diffusion tensor imaging (DTI) in normal adult patella cartilage and discuss its clinical significance.Materials and Methods: One hundred and fourteen healthy normal adult volunteers were underwent MRI with 3.0 T MR system (Achieva 3.0 T, Philips), the right patella cartilage was scanned by 3D-DESS and DTI. Different images were obtained, while the ADC and FA values of patella cartilage were measured.Results: The values of ADC were gradually decreased with age, but the ADC values were increased obviously (P<0.05). Statistically significant negative correlations were observed between FA value and age (r=-0.8321, P=0.027<0.05), and positive correlations were observed between ADC value and age (r=0.698, P=0.015 <0.05).Conclusion: DTI can reflect the imperceptible changes in patella cartilage composition and the collagen fiber structure. DTI can be used for detecting early diagnosis, monitoring progression and evaluating prognosis in patella cartilage disease for its good repeatability and accuracy.
