[The differential diagnosis of neuroepithelial tumors and meningiomas of the brain by using magnetic resonance tomography (field strength of 0.04 T)].
A study was made of the magnetic resonance imaging (MRI) data on 7 patients with primary neuroepithelial tumors located in the peripheral parts of the hemispheres and 9 patients with convex meningiomas. Tumors were verified by histological examinations in all the cases. MRI was performed on an apparatus Magnaview (Instrumentarium Company, Finland) in different impulse sequences and planes. The images were estimated quantitatively according to the tumor-to-white matter ratio and signal-to-noise ratio. It has been shown that the use of the complex of the macromorphological signs combined with the parameters under consideration enables one to differentiate between neuroepithelial tumors and meningiomas of the brain practically with-out error.
