Results: Non Contrast MRI appearance of tumor-like cerebritis is of long T1 and long T2 signal but has no characteristic features.

结果：肿瘤样脑炎的非增强磁共振成像表现为长T1、长T2信号，缺乏特征性，其CEMRI表现为（1）斑片状高信号，大小不一，强弱不一，散在分布。

MRI is more sensitive than CT to distinguish the cerebritis stage from the capsule stage. Conclusion: MRI features of brain abscess were well corelated to the clinical stages and pathological changes. MRI is powerful in the determination of clinical stages of brain abscess.

脑脓肿的MRI特征与其临床分期及病理学变化的相关性较好，能更加准确、简便、迅速地区别脓肿的脑炎期和包膜形成期，可作为临床诊治脑脓肿的有力参考。

METHODS摘要: Fourteen patients proved pathologically as brain abscess and 17 cystic/necrotic metastatic tumor underwent conventional MRI and DWI examinations. DWI signal and ADC value were evaluated in cerebritis stage, capsule formation stage, and evolution stage of brain abscess and compared with those of cystic/necrotic metastatic tumor. Chisquared test and t test were performed for statistic analysis.

方法摘要：病理及临床证实脑脓肿14例，坏死囊变脑转移瘤17例，经常规磁共振检查及弥散加权检查，在脑脓肿脑炎期、包膜期及吸收期进行弥散信号及ADC值的测量，并和坏死囊变脑转移瘤相比较，统计学分析采用χ2检验和t检验。

Results: The cerebral paragonimiasis appeared as follow: type of cerebritis in 5 cases, type of cyst in 2 cases. On plain CT, the type of cerebritis presented patchy low-density or heterodensity areas; the type of cyst presented irregular cystic low-density areas.

结果：7例中 5例为脑炎型，CT平扫病灶为片状低密度或不均匀混杂密度灶。2例为囊肿型，平扫呈不规则囊状低密度。
