| Abstract: | Diffusion weighted imaging (DWI) is a specialized magnetic resonance imaging technique that depends on the random movement of water molecules within and between the intracellular and extracellular spaces. Regions with restricted mobility of water molecules yield a greater DW-MRI signal and appear bright. In apparent diffusion coefficient (ADC) maps, regions that contain high water mobility appear bright. Purpose: The objectives of the study were to describe the imaging characteristics of intra cranial lesions on DWI and to compare these features with ADC and T2W images. Results: In this study all cases (100%) of acute infarcts showed true diffusion restriction. 13% of acute infarcts showed no signal change on T2W images. The rest were hyperintense on T2WI. 50% of subacute infarcts and none of the chronic infarcts showed diffusion restriction. All cases of subacute and chronic infarcts were hyperintense on T2WI. All cases of abscesses showed diffusion restriction. The cystic or necrotic component of none of the tumors seen in this study showed true diffusion restriction. Extradural empyema showed restricted diffusion. 40% of cases of glioblastoma multiforme showed true restricted diffusion while none of the low grade gliomas or anaplastic astrocytomas showed diffusion restriction. |
