T2-weighted signal hyperintensity
WebThe T2-weighted MRI revealed hyperintensities of the spinal cord parenchyma at the level of the third thoracic vertebra and the 5 th -6 th cervical vertebral disc space, suggesting fluid in the spinal cord. The hyperintensity in these regions was less but still visible on T1-weighted images, supporting inflammation or hemorrhage (Figure 4).
