Results There were all 129 cases（97％） with hydrothorax,which showed as 3 types.14 cases （67%） from 21 cases of tumor were found with lumps;1 case of central type of lung cancer and 1 case of lobar pneumonia had shown an appearance of consolidation of lung and the similar sonographic appearance to liver;the cases of hemopneumothorax the medical record of surgical trauma.

To evaluate which combinations of preprocessing and differential expression method perform well, we consider 4 popular preprocessing methods (MAS 5.0, RMA ,dChip and PDNN) and 5 popular differential expression methods (fold-change, two sample t-test, SAM, EBarrays and limma).

为了评估各种预处理方法与表现量差异方法组合的表现，我们考虑了四种常用的预处理方法：MAS 5.0、RMA、dChip及PDNN，与五种常用的表现量差异方法：fold-change、two sample t-test、SAM、EBarrays及limma。

Results Lymphadenectasis of different reasons reflected different pathologic changes, but their ultrasonic manifestations might be overlapping, and the same disease might show the different manifestations and pathological changes in different phases.

Objective To analyze the CT and MRI manifestations of oral carcinoma,and to evaluate the value of imaging technologies in the diagnosis of oral carcinoma,thus to explore the most reasonable imaging method Methods 46 cases with oral carcinoma,proved by surgery and pathology （2 lip tumors,8 carcinomas of the gingival ridge,5 carcinomas of the buccal mucosa,24 tongue carcinomas,5 carcinomas of the floor of the mouth,2 tumors of the hard palate）,were analysed retrospectively32 cases were examined with CT and 14 cases with MRIImaging presentations were compared with surgery and pathology Results Of the 46 cases with oral carcinoma,22 were ulcerative lesion of infiltrative growth,24 were masslike lesion of extruded trowthOf the 32 cases examined with CT scan,27 were detected,5 were missed,the 4 missed cases were confirmed to be superficial ulcers by surgery and pathologyOf the 10 cases with bone destruction examined with CT scan,8 were manifested,2 were missedAnd of the 14 cases with MRI scan,all 14 were detected Conclusion CT and MRI scan are valuable for diagnosis of oral carcinomasThey can manifest the morphology and size of primary tumor,contiguous structures,bone invasion and cervical lymph node metastasisMRI is the optimal imaging method for superficial ulcerative lesion of infiltratibe growth

中华硕博网核心提示：徐锋，罗德红，唐威，欧阳汉，周纯武关键词：口腔肿瘤目的分析口腔癌的CT及MRI表现，评价影像检查在口腔癌诊断中的应用价值，探徐锋，罗德红，唐威，欧阳汉，周纯武目的分析口腔癌的CT及MRI表现，评价影像检查在口腔癌诊断中的应用价值，探索合理的影像学检查方法。方法回顾性分析经手术及病理证实的口腔癌46例（唇癌2例，牙龈癌8例，颊黏膜癌5例，舌癌24例，口底癌5例，硬腭癌2例），其中32例行CT扫描，14例行MRI扫描，将影像表现与手术所见及病理结果进行对照分析。结果46例口腔癌中，呈浸润性生长的溃疡型病变22例，外生性生长的肿物型病变24例。CT扫描32例，明确显示病变27例，遗漏病变5例，其中4例为表浅溃疡型病变。CT扫描病例中，10例有骨质侵犯，CT扫描准确评价8例，遗漏2例。MRI扫描14例，均准确评价肿瘤及其与四周结构的关系。结论 CT、MRI对口腔癌原发肿瘤的形态、大小、四周结构侵犯、颈部淋巴结转移的评价有重要价值。对于较小及呈浸润性生长的表浅溃疡型肿瘤，CT扫描尤其是CT平扫难以准确显示，应首选MRI。
