摘要
目的:探讨CT灌注成像(CTPI)和磁共振弥散加权成像(DWI)在急性脑梗死诊断中的价值。方法:回顾性分析58例临床诊断为急性脑梗死患者的临床及影像学资料,其中超急性期18例,急性期40例,所有患者均行DWI扫描,18例超急性期患者并行CTPI扫描。结果:急性期患者DWI全部显示高信号;超急性期患者17例CTPI显示异常灌注,15例DWI显示高信号。结论:CTPI和DWI可以超早期诊断急性脑梗死,为临床早期溶栓及个体化治疗提供影像学依据。
Objective： To evaluate the CT perfusion imaging （CTPI） and magnetic resonance diffusionweighted imaging （DWI） in acute diagnosis of cerebral infarction. Methods： Retrospective analysis of 58 cases of clinically diagnosed as acute cerebral infarction in patients with clinical and imaging data, including 18 cases of super - acute stage, 40 cases of the acute phase, all patients underwent DWI scan, 18 cases of patients with hyperacute CTPI parallel scan. Results：All patients with acute DWI showed high signal; super - acute phase CTPI showed 17 cases of patients with abnormal perfusion, 15 cases of DWI showed high signal. Conclusion： CTPI and DWI can be super-early diagnosis of acute cerebral infarction, thrombolytie therapy for clinical early and individualized treatment based on imaging.
