A CT scan can detect brain lesions, but it's not the preferred tool for diagnosing MS in the cervical spine. MRI is the gold standard for spotting MS lesions because it produces much more detailed images of the spinal cord's soft tissue. Here's why MRI is preferred over CT for cervical spine MS imaging:
- MRI shows greater detail in brain tissue, the brainstem, and the spinal cord
- It can detect small lesions that CT scans would likely miss
- A contrast dye called gadolinium can be used during MRI to highlight active, inflamed lesions vs. older ones
- CT uses radiation, while MRI uses magnetic fields — making MRI a safer repeated-use option
If your neurologist suspects MS activity in your cervical spine, they will almost certainly order an MRI rather than a CT scan. It's always worth asking your care team which imaging is most appropriate for your specific situation.
