Multiple falls can injure joints (knee pain). In equivocal cases, CT myelography can help localize the dural defect and conventional myelography shows real-time movement of CSF, so that other causes of intradural filling defect such as arachnoid cyst can be excluded (62). Figure 2a. Spinal cord infarction is a rare cause of acute myelopathy, accounting for about 6% of cases of myelopathy (30). Once artifacts and extrinsic compression are excluded as possible causes of cord SI abnormality, the remaining cord SI alterations can be considered intrinsic to the spinal cord.

Nonetheless, imaging of the cord in suspected ALS can help confirm the diagnosis, exclude other causes, and monitor progression (50,51). No statistically significant differences were found in recovery rates between cases with T2 signal intensity changes and those with no signal intensity changes. Filters.

Spinal cord compression is caused by a condition that puts pressure on your spinal cord. The excellent spatial resolution of images acquired using FIESTA (fast imaging employing steady-state acquisition) sequences at MRI may improve detection (63,64). Pathological tissue usually has more water than normal brain so this is a good type to scan to pick this up.
