Idiopathic inflammatory myopathy IIM (generally called Myositis) is a rare but serious condition characterised by the presence of skeletal muscle inflammation, causing muscle weakness and disability (Targoff 1998, Karpati and Hilton-Jones 2001, Harris-Love 2003, Sultan et al 2002, Plotz 9). There is no 'Gold standard' test for diagnosing this disease which makes it challenging for physician. However, tests such as; muscle electromyogrphy (EMG), Creatine kinase serum (CPK) and biopsy are the best in current practice (Harris-Love 2003, Sultan et al 2002, Plotz 1989). All previous tests have their limitations. MR imaging has been successfully used to evaluate patients suspected of having IIM. MR images are reported following visual analysis by radiologists. In this research, two approaches were used to improve the diagnosis of Myositis with the aid of MRI.
