In MR imaging, T2-weighted images are useful in the diagnosis of intramedullary spinal cord diseases. But edema, inflammation, demyelination, and tumor are nonspecifically seen in the high in tensity area. It is therefore difficult to distinguish between tumor and multiple sclerosis. In this study, the manipulation of the window level and width on T1-weighted images, which should be superior in appearance, showed new findings and were effective in the diagnosis of intramedullary spinal cord diseases.
