Results 20 cases of CT examination had made proper diagnoses,the CT imaging finding about the most of peripheral cholangiocarcinoma included:There was the atactic low density tumour in liver,its borderline was unclear,enhanced scan appearances were irregular peripheral enhancement,centripetal enhancement,and delaying enhancement;There was concretion and dilatation of bile buct in or around the focus;The local envelope of liver was lacunose and the local liver was atrophied,There was abroad putrescence and liquescence in the focus.

结果 20例CT做出了正确的诊断，大部分周围型胆管细胞癌的CT表现为肝内不规则低密度肿块边界欠清，增强扫描表现病灶边缘呈不规则环状强化，有向心性强化的趋势，出现延迟强化；病灶内或周围可见结石，病灶内及周围肝内胆管扩张；局部肝包膜回缩、肝叶萎缩，病灶内大片坏死、液化。

Curvilinear calcification suggests an aneurysm but is a less specific finding because it can also occur in craniopharyngiomas and sphenoidal masses. The intense enhancement of the residual lumen is relatively specific, but differentiation from other masses may be difficult on CT scans depending on the timing and degree of vascular enhancement. The MR imaging features are usually diagnostic, although they can be very subtle [2]. Significant signal heterogeneity is seen with T1 hyperintense signal due to subacute thrombus or flow related enhancement. Areas of T2 hypointensity can be seen due to intracellular deoxy or methemoglobin, calcification, or flow void.

线样钙化提示动脉瘤，但不是一个非常特异的征像，因为这也可以见于颅咽管瘤和蝶骨肿瘤，管腔样明显强化更特异些，但是在CT上与其他肿瘤鉴别可能是困难的，因为这取决与增强的时间与血管强化的程度，MR的特征性表现是更具有诊断意义的，即使有时候可能表现的非常细微，在T1上可以看到明显的不同信号成分，这是由于亚急性的血栓或流动相关增强效应，T2序列上可以看到低信号区域，这是由于细胞内脱氧或高铁血红蛋白，钙化，或流空效应。

Three hundred and twenty-four crossbred (Landrace×Yorkshine) barrows with average body weight of 27 kg were randomly assigned to 6 dietary groups: group Ⅰ(chlorotetracycline group, added 50 mg/kg chlortetracycline in basal diet); group Ⅱ(origanum oil group, added 20 mg/kg oreganum oil in basal diet); group Ⅲ(probiotics group, added 1.5 g/kg probiotics in basal diet); group Ⅳ(nutrient enhancement group, elevated dietary vitamin E, vitamin B family and micro elements Zn, Mn, I); group Ⅴ(origanum oil+nutrient enhancement group); group Ⅵ(probiotics+nutrient enhancement group).

Sources have it that the incidence rate of intracranial gliomas postoperative reactional enhancement is 65.7%(134/204), whereas that of tumor residual is 34.3%(70/204) [1]. The network is capable of learning and memorizing, and can memorize the data diffusion features. Therefore, if data with such rates are employed to train the network, it will overstudy reactional enhancement. Even though the network training is not successful and all are diagnosed as reactional enhancement, the correctness will be still as high as 65.7%.

据文献报道，胶质瘤术后反应性强化的发生率是65.7%(134/204)，肿瘤残存发生率是34.3%(70/204)[1]，因为网络具有学习和记忆功能，能够记住数据的分布特点，因此用此比率的数据训练网络，对反应性强化会过度学习，即使网络训练不成功，全部诊断为反应性强化，正确率仍然高达65.7%。
