This study was performed on 73 patients who had inflammation in knee joint with age ranging from 18-65 years. DTI and DCE-MRI were performed on a 3T MR scanner. On discriminant analysis, DCE derived BV and DTI derived FA values were found to be significant discriminators between tubercular and non-tubercular inflammation with canonical correlation of 0.851. We were able to correctly classify a total of 98.6% of original grouped cases into tubercular and non-tubercular knee arthritis with very narrow range of overlapping values.
