目的:探讨MR诊断AIDS脑部病变的诊断价值和临床意义,总结其影像特征。材料与方法:分析39例AIDS患者的临床及脑部MR影像资料。结果:本组15例为MR检查疑似AIDS患者,经验血后予以证实。39例患者中脑萎缩33例,32例脑异常信号病例中病灶多发320例,病变以额顶叶居多,脑部病灶大小相差较大,形态表现多样,可多种形态并存,占位效应相对较轻。病灶大多呈T1WI像低信号,T2WI及Flair高信号,Flair序列对病灶的显示较清,病灶增强后强化或不强化,弓形体脑炎占大多数。结论:MR在诊断AIDS患者脑部病变方面具有较高的诊断价值和重要的临床意义。
Objective: To investigate the diagnostic value and clinical significance of MR in the diagnosis of brain lesions and to summarize its imaging features. Materials and Methods: Clinical and brain MRI data of 39 AIDS patients were analyzed. Results: The group of 15 cases of suspected AIDS patients with MR examination, confirmed by the blood test. 39 cases of brain atrophy in 33 cases, 32 cases of abnormal brain signals in 320 cases of frequent lesions, the frontal parietal lobe lesions mostly, the larger the size of brain lesions, morphological diversity, the coexistence of multiple forms, occupying effect relative Lighter. Most lesions were T1WI like low signal, T2WI and Flair high signal, Flair sequence showed more clear lesions, lesions enhanced or not strengthened, Toxoplasma encephalitis accounted for the majority. Conclusion: MR has high diagnostic value and important clinical significance in the diagnosis of brain lesions in AIDS patients.
