The objective of this book is to assess the diagnostic value of direct MR arthrography compared to conventional MR imaging in assessment of the normal anatomic structures of the wrist joint as well as in the diagnosis of different pathologic entities specially those affecting the triangular fibrocartilage and intrinsic ligaments of the wrist joint. A comparison of the results of conventional MRI versus MRA was done by correlating the final diagnosis of each modality with the results of arthroscopy. MR arthrography is a potent additional tool facilitating the diagnosis of different pathologic entities affecting the TFC and internal ligaments of the wrist joint and helps to reduce arthroscopic interventions.
