目的:弥散加权MRI(DWI)对急性脑梗死,尤其是超急性脑梗死较常规MRI有更高的敏感性,与常规T2WI、T1WI成像结合,可鉴别急性与非急性脑梗死。方法:搜集本组50例脑梗死患者行常规扫描序列和弥散扫描序列,T1WI、T2WI、Flair及ADC图。结果与结论:DWI结合ADC图运用于临床,为更早发现脑梗死灶,争取超急性脑梗死的治疗时间,减少伤残和死亡,提供直观的影像学依据,是医学影像学发展的又一重大进步。
AIM: Diffusion-weighted MRI (DWI) is more sensitive than conventional MRI for acute cerebral infarction, especially for hyperacute cerebral infarction. Combined with conventional T2WI and T1WI imaging, acute and non-acute cerebral infarction can be identified. Methods: The 50 patients with cerebral infarction were collected routine scan sequence and diffuse scan sequence, T1WI, T2WI, Flair and ADC maps. RESULTS AND CONCLUSION: The combination of DWI and ADC maps in clinical application provides an intuitive imaging basis for early detection of cerebral infarction, striving for the treatment of hyperacute cerebral infarction, reducing disability and death, and is another development of medical imaging Significant progress.
