RT Journal Article SR Electronic T1 Serial biplane magnification and subtraction myelocisternography: normal and pathologic findings. JF American Journal of Neuroradiology JO Am. J. Neuroradiol. FD American Society of Neuroradiology SP 55 OP 63 VO 2 IS 1 A1 T El Gammal A1 B S Brooks YR 1981 UL http://www.ajnr.org/content/2/1/55.abstract AB A modified technique for performing Amipaque myelocisternography is described and results obtained in the first 100 patients are analyzed. Diagnostic quality examinations were obtained in 90% of patients in whom the technique was employed. The complication rate was comparable to studies using C1-C2 puncture and to other reports using Amipaque contrast medium. This examination is valuable for high cervical and craniocervical junction lesions, cervical cord atrophy or enlargement, cerebellar ectopia, lower cranial nerve neuropathies, and cerebellopontine angle problems, especially the early detection of small acoustic neurinomas.
