A total of 17 patients (seven detected tubercular and 10 with inflammatory arthritis) were imaged using both conventional and DT MRI. It was found that DTI derived FA and CL of synovial membrane were significantly higher in tubercular arthritis as compared to the non-tubercular ones. In synovial fluid, apart from FA and CL, CP was also significantly higher in tubercular arthritis, while MD values were significantly lower than inflammatory arthritis. We conclude that DTI can non-invasively differentiate between chronic inflammatory arthritis from tubercular arthritis which is of importance in appropriate management of these patients.
