  • Look Inside

On MR images the spinal cord is seen differently in size depending on imaging parameters and dis-playing window ; consequently the findings may be interpreted erroneously as swelling or atrophy of the spinal cord. The purpose of this paper was to evaluate factors influencing spinal cord size on images and to determine the optimal condition estimating the size of the spinal cord. At first we selected 4 cases suspected of cervical spinal dis-orders which had been examined by both MRI and myelography with tomography. Sagittal diameter of the spinal cord was measured on a film and it was significantly different of those three. That is, the measurement value was greater on T1 weighted image (T1 WI) and smaller on T2 weighted image (T2WI) than myelo-tomography.
