摘　　要：目的探讨大面积脑梗死患者的CT、MRI表现及临床诊断价值。方法选取我院2010年2月至2015年2月的88例大面积脑梗死患者进行CT和MRI诊断,分别对12h,24h,72h内的患者进行CT、MRI检查,比较CT和MRI检查的检出率及影像学表现。结果随着时间的延长CT检查的患者脑组织水肿逐渐加重,梗死区域脑组织密度不断下降;MRI检查的病灶T1WI呈低信号,T2WI呈高信号,DWI呈明显高信号,ADC图呈低信号;MRI的总检出率(97.7%)明显高于CT(75.0%),具有统计学意义(P<0.05);MRI对入院后患者12h,24h的的检出率(90.9%,100.0%)明显高于CT(45.5%,60.0%),具有统计学意义(P<0.05);CT和MRI在72小时检出率均为100%,没有显著差异(P>0.05)。结论 MRI检查大面积脑梗死患者的检出率明显比CT高,可以准确的判定患者的发病情况。Objective To study the CT and MRI manifestation of large area cerebral infarction patients and the clinical diagnostic value.Methods From February 2010 to February 2015, Selected 88 cases patients with large area cerebral infarction of CT and MRI to diagnosis in our hospital , respectively for 12 h, 24 h, 72 h in the patients with CT, MRI, compared CT and MRI detection rate and imaging manifestations.Results As the extension of time CT examination of brain edema in patients had progressive, brain infarction area density of falling. MRI lesions T1WI low signal, T2WI showed high signal, DWI was obviously high signal, can the ADC figure had low signal; the total detection rate （97.7%） of MRI was obviously higher than that of CT （75.0%）, with statistical significance （P〈0.05）, for hospital patients after 12 h, 24 h detection rate （90.9%, 100.0%） MRI were significantly higher than that of CT （45.5%, 60.0%）, with statistical significance （P〈0.05）. CT and MRI detection rate was 100% in 72 hours, no significant differences （P〉0.05）.Conclusion The detection rate to the large area cerebral infarction were examined by MRI is higher than CT, can accurately determine the incidence of patients.
