Diffusion Weighted Magnetic Resonance Imaging Features of Intracranial Lesions
Journal Title: International Journal of Contemporary Medicine surgery and Radiology - Year 2018, Vol 3, Issue 2
Abstract
Introduction: DWI (Diffusion Weighted Magnetic Resonance Imaging) has a wide range of applications in the evaluation of intracranial pathological conditions. Study was done to describe the features of intracranial lesions on DWI and to compare these features with ADC and T2 FLAIR images. Material and methods: DW MRI Study was undertaken in 110 patients admitted with suspected intracranial lesions. All the MRI scans in this study were performed using 1.5 T MRI scanner. Results: 41(37.3%) females and, 69 (62.7%) males were present in the study. The age of the patients ranged from 6 years to 80 years. Infarcts, infective conditions, extra axial mass lesions, intra axial mass lesions, and other conditions like demyelination, posterior reversible encephalopathy syndrome were included in this study. Infarcts comprised the majority of lesions at 56 cases (50.9% of the total cases studied). Of these acute infarcts constituted 34 cases (60.7%); 19 (33.9%) were chronic infarcts and 3 (5.3%) were subacute infarcts. All cases of acute infarcts and 66.7% of subacute infarcts showed diffusion restriction. Among intra axial tumors true restriction was noted in 7 cases. 75% of glioblastoma multiforme showed true diffusion restriction. 100% of medulloblastomas and 100% of lymphomas showed diffusion restriction. Conclusion: Diffusion weighted MRI has been proven to be of excellent use in the characterization of infarcts and in the detection of acute infarcts
