脑梗死是由于脑组织局部供血动脉血流的突然减少或停止,造成该血管供血区的脑组织缺血、缺氧,导致脑组织坏死、软化,并伴有相应部位的临床症状和体征,是一种很常见的脑血管疾病。如何进行早期诊断、早期治疗一直是临床关注的热点。脑梗死的早期诊断有助于临床实施正确的治疗方案及判断预后。常规磁共振成像(MRI)、CT对超早期脑梗死病变常无阳性发现,弥散加权成像(DWI)技术日益受到临床的关注,使得在脑梗死超急性期显示梗死的
Cerebral infarction is due to a sudden decrease or stop of local arterial blood flow in brain tissue, resulting in ischemia and hypoxia of brain tissue in the blood supply area of the blood vessel, resulting in necrosis and softening of the brain tissue with accompanying clinical symptoms and signs A very common type of cerebrovascular disease. How to diagnose early, early treatment has been the focus of clinical attention. Early diagnosis of cerebral infarction helps to implement the correct clinical treatment and prognosis. Conventional magnetic resonance imaging (MRI), CT often non-positive findings of ultra-early cerebral infarction, diffusion-weighted imaging (DWI) technology is increasingly clinically concerned, making the infarction in the acute phase of cerebral infarction
