摘　　要：非对比剂功能MR成像用于急性脑梗死的诊断及临床预后评估,具有无创、简便快捷及可重复性好等优势,可为MR灌注成像提供补充信息。临床上常用的非对比剂MR成像技术包括扩散加权成像、磁敏感加权成像、动脉自旋标记、液体衰减反转恢复、MR血管成像等。对非对比剂功能MRI用于评估急性脑梗死预后神经功能、梗死体积、出血性转化、溶栓疗效等进展进行综述。Non-contrast agent MRI imaging is used in diagnosing and evaluating the clinical prognosis of acute cerebral infarction, which has the advantages of non-invasive, simple, fast and reproducible. It can provide supplementary information for MRI perfusion imaging. Clinically, the commonly used non-contrast MRI imaging techniques include diffusion weighted imaging（DWI） and susceptibility weighted imaging（SWI）, arterial spin labeling（ASL）, fluid attenuated inver sion recovery（FLAIR）, magnetic resonance angiography（MRA） and so on. The progresses of non-contrast agent MRI in evaluating the prognosis of acute cerebral infarction, neurological function, infarct volume, hemorrhagic transformation,thrombolysis, and so on were reviewed.
