摘要
目的探讨脑出血低场强MRI表现特点,提高MRI对本病的诊断符合率。方法总结2008年7月—2010年2月期间脑出血31例患者的临床资料,分析其临床表现及低场强MRI表现特点。结果本组31例脑出血患者中,出血部位于基底节区25例,占80.6%,其中左侧基底节11例（35.5%）,右侧基底节14例（45.1%）;左额叶2例,占6.5%;右丘脑3例,占9.7%;右颞叶1例,占3.2%。病灶最小0.7cm×1.0cm,最大7.5cm×7.0cm。MRI表现为TlWI等信号23例,表现为稍高信号8例;T2WI均表现为高信号,病灶周围伴环行水肿带11例,厚约13mm,表现为T1WI环行稍低信号,T2WI高信号,边界模糊;侧脑室内出血亦表现为TlWI等或稍高信号,T2WI高信号。结论 MRI可对超早期脑出血做出快速、准确定位和定性诊断,在脑出血后血肿周围水肿机制的研究及脑梗死溶栓治疗病例的筛选、出血性并发症的预防及预后判断等方面均有实用价值.
Objective To study the low-field MRI cerebral hemorrhage performance characteristics,improve the MRI diagnosis of the disease rate.Methods July 2008-February 2010 totally 31 cases of cerebral hemorrhage the clinical data,clinical manifestation and the performance characteristics of low field MRI were summarized.Results Totally 31 patients with cerebral hemorrhage,bleeding in the basal ganglia in 25 cases,accounting for 80.6%,of which the left basal ganglia in 11 cases（35.5%）,right basal ganglia in 14 cases（45.1%）;left frontal lobe 2 cases,6.5%;the right thalamus in 3 cases,9.7%;the right temporal lobe in 1 case,3.2%.The smallest lesion 0.7cm × 1.0cm,maximum 7.5cm × 7.0cm.MRI showed TlWI other signals in 23 cases,8 cases showed slightly higher signal;T2WI showed high signal lesions with ring surrounding edema in 11 cases,a thickness of 1 ~ 3mm,showed slightly low signal ring T1WI,T2WI high signal,the fuzzy boundaries;ventricle hemorrhage also showed TlWI or slight signal,T2WI high signal.Conclusion MRI can be made on the ultra-early brain hemorrhage quickly and accurately determining the location and diagnosis of cerebral edema after intracerebral hemorrhage and cerebral mechanisms of thrombolytic therapy in selected cases,the prevention of bleeding complications and prognosis have practical value.
