[The dynamic NMR tomographic picture after cerebral revascularization in patients with ischemic stroke].
The authors discuss the results of a MR tomographic examination in 12 patients with ischemic apoplexy who underwent operation for the formation of an extra-intracranial microanastomosis. It is shown that MR tomography is a valuable diagnostic method which allows visualization of the ischemic foci. It is proved that in combination with CT it yields valuable information for determining the indications for revascularization of foci of ischemia in the brain.

[Magnetic resonance tomography in the diagnosis of tumor processes in the area of the cerebellopontile angle].
The paper provides the results of magnetic resonance tomographic examination of patients with acoustic neurinoma, and shows that the method can be used in the defining the site of a focus, its size, and relations of the tumor with adjacent tissues. The paper also outlines the image structure of the tumor in relation to scanning techniques and gives magnetic resonance criteria for differential diagnosis of tumor processes in the region of the cerebellopontine angle. It is concluded that magnetic resonance tomography is of high informative value in the diagnosis of extra-axial tumors of the posterior cranial fossa.
