Abstract

Objective:To evaluate the clinical value of magnetic resonance diffusion weighted imaging(DWI) in the diagnosis of acute cerebral infarction. Methods:52 patients with acute cerebral infarction underwent DWI were analyzed,staged by the onset time. Results:10 cases were classified as hyperacute cerebral infarction,and 100% of new lesions were displayed on DWI, but there were no abnormal findings on T1-FLAIR, while only two cases were displayed on T2 WI and T2-FLAIR. 42 cases were classified as acute cerebral infarction, 100% of lesions were on all sequences(T1-FLAIR, T2 WI, T2-FLAIR and DWI), and displayed clearer and more intuitive on DWI. Conclusion:DWI is superior than conventional MRI for the location and staging of acute cerebral infarction. This technique has a high sensitivity for the diagnosis of hyperacute, acute cerebral infarction.
