[Computer-tomographic cisternography with amipaque].

As compared to ordinary computer tomography, computer-aided tomographic cisternography (CTC) demonstrates better the anatomy of the brain cisterns and at the same time gives an idea of the processes of c.s.f. circulation in dynamic examination. The article discusses the results of examination of 112 patients with various neurosurgical diseases by means of CTC. A detailed classification of the brain cisterns is given. The authors show the advantages of the method in examination of patients with small three-dimentional processes in the chiasma-sellar region, cerebellopontine angle, and posterior cranial fossa, with the syndrome of an "empty" sella turcica, cystic structures, and disorders of c.s.f. circulation.
