Clinical Application of MRI Diffusion-weighted Imaging (DWI) in Acute Ischemic Cerebral Infarction

Objective To investigate the diffusion weighted magnetic resonance imaging (Diffusion-weighted imaging DWI) in acute ischemic cerebral infarction in clinical application. Methods 80 cases of 3～24 hours, suspected acute ischemic cerebral infarction were DWI and routine MRI scan results were analyzed. Results The onset time of 6 hours, super acute cerebral infarction in 7 cases, conventional T2WI and FLAIR showed no abnormal signal changes, hyperintensity on DWI, ADC showed low signal.The onset time of 6～24 hours, during the acute phase of cerebral infarction in 73 cases, DWI signal change was T2WI, FLAIR sequence was significantly more accurate location, display, range. Conclusion Magnetic resonance diffusion weighted imaging in acute ischemic cerebral infarction than the conventional MRI sequences sensitive, short examination time, can provide early evidence for clinical treatment, should be used as a routine sequence in.
