摘要: Postmortem histopathology of eight gliomas was studied in correlation with magnetic resonance imaging (MRI) and computed tomography (CT) findings. MRI demonstrated the lesions more clearly widely than CT. Also, T2-weighted images (T2WI) had a greater ability to depict lesion T1-weighted (T1WI). The areas which neoplastic cells invaded corresponded high intensity on T2WI four cases glioblastoma multiforme. In case grade II astrocytoma, were scattered beyond region corresponding area T2WI. III did not come up line margin remaining two cases, although depicted as being larger seen histopathologically, regions outside zones tumour-infiltrated thought be radiation necrosis one 'periventricular intensity' other. cellularity glioma mainly low T1WI an isointensity or slightly However, signal intensities MRI, reflecting T1 T2 values tumour tissues, correlate malignancy tumour.
