急性脑梗塞磁共振FLAIR序列与T_2WI加权像对比分析

目的比较磁共振FLAIR序列和常规SE序列T2WI加权像在急性脑梗塞中的敏感性。方法69例急性脑梗塞患者接受FLAIR序列和常规T2WI检查,评价病变的显示范围、边界及对比度。结果在69例急性脑梗塞中FLAIR序列显示病灶87个,T2WI加权像显示病灶43个,有44个梗塞病灶仅在FLAIR序列中显示,27个病灶的信号强度、范围及边界在FLAIR序列较T2WI加权像显示清楚。结论FLAIR序列显示病灶较T2WI加权像信号高,特别是临近脑室、脑沟及脑池的脑梗塞病灶,在诊断急性脑梗塞中较T2WI加权像敏感,可作为常规颅脑检查的补充序列。

Use of Magnetic Resonance with FLAIR Pulse Sequence and the T2WI Weighting Image in Acute Cerebral Infraction

Objective To discuss the performance of Magnetic Resonance with FLAIR PulseSequence and the T2WI Weighting Image in the patients with acute cerebral infarction, and analyze the sensitivity of MRI with double sequence in the acute cerebral infarction.Methods The study analys ed a total of 69 cases with acute cerebral infarction by the magnetic resonance with FLAIR sequence and the T2WI weighting image, and correlatively comparased.Results Our results revealed that there 87 focus of disease were detected in FLAIR sequence, 43 focus of disease were detected in T2WI weighting image, but 44 focus of disease only to be demonstrate in the FLAIR sequence, 27 focus of diseases signal strength, the scope and the boundary compare the T2WI weighting image to be clear in the FLAIR sequence.Conclusion It is concluded that the FLAIR sequence can suppress the signal of cerebrospinal fluid, demonstrated focus of disease compares the T2WI weighting to like the signal to be high, specially focus of cerebral infarction approaches brain ventricle, the brain ditch and the brain pond, so that in the diagnosis of acute cerebral infarction FLAIR sequence compares the T2WI weighting image to be sensitive, and may take the supplement sequence of acute cerebral infarction inspection.
