摘要
目的研究MRI诊断脑梗死FLAIR序列和常规SET2WI序列的临床应用价值。方法对51例经常规MRI诊断为脑梗死的患者进行FLAIR序列成像,并与SE序列T2加权像比较。结果SET2WI显示急性脑梗死病灶105个,FLAIR显示急性脑梗死病灶110个病灶,有2个脑干部位病灶仅为SET2WI显示,而SET2WI显示的腔隙性病灶经FLAIR序列显示其中有10个为低信号,考虑为血管周围间隙,7个为低信号伴周围高信号,考虑为陈旧性脑梗死灶,未予计算在内。结论急性脑梗死诊断中FLAIR序列成像与SET2WI序列互为补充,应作为常规序列使用。
Objective To study the clinical application value of FLAIR and SET2WI sequence in MRI in the diagnosis of acute cerebral infarction .Methods 51 patients with cerebral infarction identified by conventional head MR imaging were examined by FLAIR pulses equcncc.and comparition between T2 - weighted imaging and FLAIR imaging was made. Results SET2WI sequence detected 105 focus of disease FLAIR, sequence detected 110 focus of disease, and 2 brain stem focus of disease is only detected by SET2WI sequence, but in the lacunar stroke lesions by SET2WI, it is not accounted in that 10 hyperintensed spot lesions by FLARE is Virchow - Robin space and 7 hypointcnsed areas surrounded by hyperintcrsed ring is old focus of disease. Conclusion FLAIR sequence in MRI is complement with SET2WI sequence in the diagnosis of acute cerebral infarction and should be routine sequence.
