摘　　要：目的了解脑功能成像的弥散加权成像（DWI）、灌注加权成像（PWI）在急性脑梗死降纤治疗中的应用价值。方法对80例发病2～72h的脑梗死患者行MR常规及DWI、PWI检查，并将检测的结果分型。结果PWI〉DWI 48例，有半暗带存在，降纤效果最佳；PWI=DWI 12例，不宜降纤治疗；PWI〈DWI 2例，无需降纤治疗；DWI正常、PWI显示灌注缺损10例，应尽早降纤治疗；PWI、DWI都正常8例，可选择降纤治疗。结论联合使用PWI和DWI技术，可确认缺血半暗带及预测梗死后出血，准确选择降纤治疗的适应证。Objective To explore the application value of diffusion weighted imaging（DWI） and perfusion weighted imaging （PWI） in the defibrase treatment of patients with acute infarction. Methods MR convention, DWI and PWI were performed in 80 patients with clinically diagnosed acute infarct from 2 hours to 72 hours after the onset of symptoms and the results were minuted. Results The best defibrase appeared in 48 cases（PWI〉DWI） who had the area of the graphic-penumbra. It was not suitable to defibrase in 12 caess with PWI=DWI. It was not required to ddibrase in 12 caess with PWI〈DWI. It should be defibrased as soon as possible in 10 cases who had a normal performance in DWI and perfusion defect in PWI. It should be defibrased selectivity in 8 caess who had a normal performance whether in PWI or DWI . Conclusion PWI combined DWI technology may confirm ischemic penumbra and forecast hemorrhagic infarct,then the accurate choice of defibrase treatment may be performed.
