Atrophy of the cervical spinal cord has been reported in several forms of degenerative ataxia, which may be a helpful diagnostic finding in patients presenting with disequilibrium [78-80]. In patients with chronic disequilibrium due to sensory ataxia and loss of proprioception that is out of proportion to other sensory modalities and motor function, spine MRI is useful to evaluate the dorsal columns of the spinal cord (eg, compressive myelopathy, B12/copper deficiency, or tabes dorsalis neurosyphilis). MRI Head and Internal Auditory Canal With IV Contrast There is no relevant literature regarding the use of MRI head and IAC with IV contrast in the evaluation of sensory ataxia. MRI Head and Internal Auditory Canal Without and With IV Contrast There is no relevant literature regarding the use of MRI head and IAC without and with IV contrast in the evaluation of sensory ataxia. MRI Head and Internal Auditory Canal Without IV Contrast There is no relevant literature regarding the use of MRI head and IAC without IV contrast in the evaluation of sensory ataxia. MRI Head With IV Contrast There is no relevant literature regarding the use of MRI head with IV contrast in the evaluation of sensory ataxia. MRI Head Without and With IV Contrast There is no relevant literature regarding the use of MRI head without and with IV contrast in the evaluation of sensory ataxia. MRI Head Without IV Contrast There is no relevant literature regarding the use of MRI head without IV contrast in the evaluation of sensory ataxia. CT Head With IV Contrast There is no relevant literature regarding the use of CT head with IV contrast in the evaluation of isolated dizziness. CT Head Without and With IV Contrast There is no relevant literature regarding the use of CT head without and with IV contrast in the evaluation of isolated dizziness. Dizziness and Ataxia CT Head Without IV Contrast Head CT allows for evaluation of the intracranial structures; however, soft tissue contrast is inferior to MRI.
