摘要
目的探讨磁共振弥散加权成像(DWI)在脑干缺血性梗死疾病中的早期影像学表现及应用价值。方法回顾性分析55例脑干梗死患者核磁共振DWI成像的影像学表现。结果所有急性及亚急性脑梗死病灶在DWI均表现为高信号,而在常规T2加权成像中,仅表现为等或稍高信号。结论磁共振DWI成像检查能及时、早期、准确地对脑干梗死病灶予以显示,对指导临床及时采取对应治疗措施具有重要价值。
Objective To evaluate the manifestations and application value of MR diffusion-weighted imaging （DWI） in early diagnosis of brainsteam infarction. Methods DWI images of All 55 patients with brainsteam infarction were retrospectively analysed. Results On DWI imaging, all the hyperacute and acute brainsteam infarction cases showed hyperintensity areas, but it appears as normal or slightly hyperintensity on conventional MRI T2WI. Conclusion DWI can show brainsteam infarction in an early stage accurately, and DWI has important value to direct clinical treatment.
