目的探讨急性脑梗死的MR表现。方法对我院2013年12月~2014年12月,经MR检查及临床确诊的80例急性脑梗死患者进行回顾性分析,观察其MR表现。结果急性脑梗死多较表浅,靠近皮层,呈斑片状或楔形,T1WI呈低/等信号,T2WI呈等/高信号,边界较模糊,DWI上均为高信号。结论论急性脑梗死在MR上具有特征性,MR应作为首选检查方法,为临床治疗提供依据。
Objective To investigate the MR manifestations of acute cerebral infarction. Methods A retrospective analysis was performed on 80 patients with acute cerebral infarction confirmed by MR and clinical examination from December 2013 to December 2014 in our hospital. The MR findings were observed. Results Acute cerebral infarction was more superficial, close to the cortex, patchy or wedge-shaped, T1WI was low / equal signal, T2WI was equal / high signal, the border is fuzzy, DWI are high signal. Conclusions Acute cerebral infarction is characteristic of MR and MR should be the first choice for clinical diagnosis.
