摘　　要：急性脑梗死、超急性脑梗死主要由于患者脑部产生血液循环障碍,使脑部出现缺氧、缺血情况,导致局限性脑组织坏死。此疾病的产生与患者心律失常、糖尿病、肥胖、高血压等因素相关,临床主要表现为语言障碍、认知障碍、偏瘫等神经功能性损害,会对患者的身体健康产生较大影响。为有效诊断急性脑梗死、超急性脑梗死,需要为患者实施磁共振检查。根据磁共振检查结果,制订针对性的治疗方案,实现血栓、纤维蛋白等的有效溶解,使阻塞血管通畅,有效恢复缺血半暗带的生理功能及脑组织血供,有利于急性脑梗死、超急性脑梗死的缺血缺氧症状的恢复。磁共振检查能够对脑梗死病理生理情况进行有效分析,并有效预测发病时间,为临床医生实施溶栓治疗提供重要参考依据,提升患者溶栓治疗的有效性,避免产生溶栓出血。本文对急性脑梗死、超急性脑梗死患者的生理特征,磁共振在其临床治疗中的应用以及治疗指导进展进行相关论述。Acute cerebral infarction and hyperacute cerebral infarction are mainly due to the disorder of blood circulation in the patient’s brain,resulting in hypoxia and ischemia in the brain,which lead to localized brain tissue necrosis. The occurrence of this disease is related to arrhythmia,diabetes,obesity and hypertension,and the main clinical manifestations are neurological impairment,cognitive impairment,hemiplegia and other neurological impairment,which will have a greater impact on the health of patients.In order to effectively diagnose acute cerebral infarction and hyperacute cerebral infarction,it is necessary to carry out magnetic resonance imaging(MRI)examination for patients. According to the results of MRI examination,targeted treatment plans should be formulated to help patients achieve effective dissolution of thrombus and fibrin,unblocking blocked blood vessels,and effectively recover the physiological function of ischemic penumbra and blood supply of brain tissue,which is conducive to the recovery of ischemia and hypoxia symptoms of acute cerebral infarction and hyperacute cerebral infarction. MRI examination can effectively analyze the pathophysiology of cerebral infarction,effectively predict the onset time,provide important reference basis for clinicians to implement thrombolytic therapy,improve the effectiveness of thrombolytic therapy and avoid thrombolytic bleeding. This paper discusses the physiological characteristics of patients with acute cerebral infarction and hyperacute cerebral infarction,the application of MRI in their clinical treatment and the progress of treatment guidance.
