 note = {Magnetic resonance imagings (MRI) are very useful in detecting small tumors such as small acoustic neurinomas confined within the internal auditory canal, microadenomas of the pituitary gland and metastatic foci. MRI provides three-dementional concepts of anatomical structures easily and facilitates to determine operative approaches. And using recently developed techniques MRI eaisily differentiates extra-axial tumors from intra-axial ones without contrast infusion. This facilitates to predict histology of brain tumors. MRI also defines the extension of the lesion more clearly and more exactly than X-CT. Now MRI is the first choice modality of diagnostic neuroimagings in cases of brain tumors.},
