Abstract

Objective: To Compare fluid-attenuated inversion reloverly(FLAIR)sequence and diflusion-weighted imaging (DWI)sequence in evaluation of acute cerebral infarction. Methods: 14 cases of acute cerebral infaretion were examined with FLAIR and DWI sequences on1. 5T MR scanner. The extent, boundary and contrast of the lesions on all images were evaluated. Apparent diffusion coefficient (ADC)and relatine ADC (rADC) of the lesions were calculated. Results: The extent, boundary and contrast on FLAIR and Dwimageswere superior to conventional T2WI. The visualization of the lesions on DW images was proved to be the best. Conelusion: Both FLAIR and DWI sequences are more Valuble on Visualization of acute cerebral infarction than conventional T2WI sequence. DWI was the best to show the lesions,furthermore, it can assess the infarction area quantitatively.
