Localisation of spinal cord lesions by MRI was correlated with
neurological symptoms and signs in 16 patients with clinical and
laboratory evidence of multiple sclerosis. There was good correspondence
between spinal cord lesions and motor tract signs. On the other hand,
superficial or deep sensory disturbances correlated with spinal cord
lesions in only about a quarter of the patients. MRI of the spinal cord
appeared to explain the myelopathy in 11 patients, while in 3 there was
strong clinical evidence of more extensive demyelinating lesions. In 7
of the 16 patients MRI of the brain was normal
