In preliminary diagnosis system, apparent clinical symptoms were broken into seven parts in terms of general, skin/body, respiratory, digestive/excretive, locomotive/nervous, reproductive, and attack age. Users could choose symptoms what they observed in this list. The system calculated accordingly and summed up weighted value in different symptoms of individual diseases, and showed top ten possible diseases sorted by sum of weighted value. The report also could show belief percentage of top ten possible diseases by a pie chart and illustrate the basis and reasons of inference.

Results MRI appearances of acoustic neuromas were:（1）The turmor's growth round the internal auditory canal,the Ⅶ,Ⅷ nerves affected side were thickened than that of opposite side.There was no marked demarcation between the main bodies of the tumors and the affected nerves.The connection between tumors and affected nerves could be showed at contrast enhanced imaging.（2）The tumors were of hypo or isohypo intensity on T1 weighted images and hyper or iso hyper intensity on T2 weighted images.（3）After Gd DTPA administration the tumors were homogeneously or inhomogeneously or circularly enhanced.（4）The margins of the tumors were smooth and well delineated.（5）The affected internal auditory canal usually became shorter in depth and larger in posterior anterior diameter.（6）MRI appearances of micro acoustic neuromas were that the affected Ⅶ,Ⅷ nerves were normal in size or nodularly thickened and the tumor reveaed nodular or point enhancement at contrast enhanced MRI.

结果 听神经瘤的MRI表现主要为：（1）肿瘤以内听道为中心生长，第Ⅶ、Ⅷ神经束较对侧增粗，与肿瘤主体多无明确分界，增强后可见两者相连，颇为特征；（2）肿瘤在T1加权图像上呈低信号、略低信号或低等混合信号，T2加权呈高信号或高等混合信号；（3）注射Gd DTPA后肿瘤呈均匀、不均匀或环状强化；（4）肿瘤边界清晰，边缘光整；（5）绝大多数肿瘤患侧内听道前后径扩大，深径缩短；（6）微小听神经瘤的MRI表现为第Ⅶ、Ⅷ神经束正常或局部结状增粗，造影后呈结节状或点状增强。

MRI findings usually fall into 2 categories: 1 A soft tissue mass that is hypointense on T1-weighted images and hyperintense on T2-weighted images with diffuse homogeneous or slightly heterogeneous enhancement within the collection; 2 As the phlegmonous mass necroses, there may be a peripherally-enhancing fluid collection.

MRI表现通常被分为两类：1）软组织肿块，T1低信号，T2高信号，病灶内弥漫均匀性或轻度不均匀强化；2）当表现为蜂窝组织炎坏死时，表现为边缘强化的积液。

Among 14 cases of trigeminal tumor,12 cases were examined by CT scanning,2 cases by MRI,all of them were confirmed by pathological examination.The density appeared heterogeneous with 6 cases,homogeneous high density with 5 cases and isopyknic with 1 case.Dropped contrast medium,the 12 CT scanning pictures appeared heterogeneous potentialization,and there were no cerebral edema around the tumor.Among 2 cases examined by MRI,T1 weighted image appeared low signal,T2 weighted image appeared high signal.
