Multiphasic CT has moderate sensitivity in the detection of PETs. Most tumors are more conspicuous on the earlier phases of enhancement. Potential sources of false-negative results include tumors adjacent to vessels, pedunculated morphology, and nonhyperattenuating lesions.

薄层螺旋CT多期扫描对PET的检出敏感性高，多数肿瘤在增强早期显示明显，肿瘤邻近血管、蒂状突出及非高密度病灶是造成假阴性的潜在因素。

LIT was most commonly confused with malignant tumor, Crohn's disease, lymphoma and periappendicular abscess. There were 2 of 4 patients, who were performed operation. Most of our cases were not definitively diagnosed until the histopathologic examination after surgery and polymerase chain reaction.

大肠结核较易误诊为大肠肿瘤、克罗恩病、淋巴瘤和阑尾周围脓肿。4例剖腹手术者术中仍有2例(50%)被误诊为肿瘤和克罗恩病，即使活检或术后在病理学报告前仍有多数不能确诊。

Results: Relief of endobronchial tumor-related symptoms and external compression from peribronchial tumor was noted in 35 of 50 patients (70%) treated with EBBT.

结果：气管内肿瘤阻塞或气管旁肿瘤压迫所造成症状，在经过气管内近接治疗后，50位病人中35位(70%)获得缓解。

Purpose: Endobronchial brachytherapy is a useful modality for the palliation of symptoms caused by endobronchial tumor or compression from peribronchial tumor.

目的：气管内近接治疗对於气管内肿瘤阻塞或气管旁肿瘤压迫所造成症状，是一有效缓解之姑息性疗法。

Squamous cell is the most common cancer of sinonasal cavities; adenoid cystic is the most common to produce perineural spread.

鳞癌是鼻窦腔最常见的肿瘤，腺样囊性癌是最常见的累及周围神经的肿瘤

But it is more useful to detect extent of infiltration of the peripancreatic tissues, superior mesenteric artery than CT.

我们认为MR对于胰腺肿瘤的诊断尚需进一步探讨，但对于判断肿瘤侵犯的范围则有较大的应用价值。

Methods DCs were prepared from peripherad blood mononuclear induce d with gra-nulocyt e/macrophage colony-stimulating factor and interleukin-4. Apoptosis of glioma cells were induced with γ-radiation. We design these experiment groups including (1) coculture of DCs and apoptotic glioma cells and T cells,(2) coculture of DCs and U937 cells and T cells,(3) coculture of DCs and cultured glioma cell and T cells,(4) coculture of Des and T cell.

用粒－巨噬细胞集落刺激因子加白介素－4(IL-4)从人外周血分化、诱导DCs、γ-射线在体外诱导培养的人脑胶质瘤细胞凋亡，将DCs、T淋巴细胞和凋亡胶质瘤细胞共培养，同时设计不同类型肿瘤细胞（U937及培养胶质瘤细胞）作对照，分离、富集DCs、T淋巴细胞进行免疫应答及肿瘤细胞杀伤试验。

Methods DCs were pre pared from peripherad blood mononuclear induce d with gra-nulocyt e／macrophage colony-stimulating factor and interleukin-4.Apoptosis of he patochlangioma cells were induced with γ-radiation.We design these experiment groups including(1)coculture of DCs and apoptotic cancer cells and T cells,(2)co culture of DCs and necrosis cancer cells and T cells,(3)coculture of DCs and cul tured cancer cell and T cells,(4)cocultu re of DCs and T cell,(5)cocuture of DCs and cultured cancer cell.

用粒-巨噬细胞集落刺激因子加白介素-4(IL-4)从人外周血分化、诱导DCs、γ-射线在体外诱导培养的人胆管癌细胞凋亡，将DCs、T淋巴细胞和凋亡胆管癌细胞共培养，同时设计不同类型肿瘤细胞(坏死胆管癌细胞及培养胆管癌细胞)作对照，7d后，分离、富集DCs、T 淋巴细胞进行免疫应答及肿瘤细胞杀伤试验。

Results In RT-PCR analysis of the peripherial blood, 45%(18 out 40) of CRC patients, 10%(2 out 20) of CRP patients were positive for CEA mRNA, respectively. All 40 healthy individuals were negative for CEA mRNA expression. The detection of CEA mRNA was significantly correlated with TNM stage of CRC patients, while there were no significant relationship between the CEA mRNA expression and the malignant extent of cell differentiation.

结果 40例结肠癌患者外周血中CEA mRNA表达的阳性率为45.0%(18/40)，而健康对照组均为阴性，两者比较有显著性差异(P.01)；20例结肠息肉患者中CEA mRNA表达阳性率为10%(2/20)；CEA mRNA阳性表达率与肿瘤分期相关，而与肿瘤细胞分化程度并不相关。
