RESUMO
Experience with magnetic resonance imaging in 22 patients with diseases of the spinal cord is reported. Important additional diagnostic information as compared to conventional neuroradiological techniques (myelography, spinal CT) was gained especially in cases of hydrosyringomyelia, intraspinal tumour and multiple sclerosis. It is suggested that magnetic resonance imaging may become the method of choice in the diagnosis of structural spinal cord diseases.

Computerized axial tomography enables the accurate diagnosis of acoustic neuromas by non-invasive means, and it should therefore be used after conventional radiological methods. Small neuromas often only show non-specific signs and in these patients contrast cysternography is still necessary. Up to the present glomus jugulare tumours were diagnostically confirmed by angiography. Now the CT scan is recommended not only for diagnosis, but also for after-treatment follow-up and recognition of recurrent tumour growth. Tumours that infiltrate the skull base should be assessed by this method since the extent of the lesion can be exactly measured.
