【摘要】目的分析原发性小肠肿瘤的影像特点,探讨螺旋CT及DSA检查应用价值.方法回顾分析26例小肠原发性肿瘤的影像表现.26例均行口服钡剂造影,11例超声检查,6例螺旋CT检查,4例DSA检查.结果口服钡剂造影主要表现为充盈缺损、管腔狭窄,螺旋CT主要表现为肠壁增厚、软组织肿块,DSA主要表现为肿瘤染色、出血.CT诊断6例,与病理相符5例;DSA诊断4例,与病理相符3例.结论小肠原发性肿瘤具有一定的影像特点,结合临床可提高诊断,螺旋CT与DSA检查明显提高肿瘤的定性诊断率.

多层螺旋CT动态增强扫描对小肠原发性肿瘤的诊断价值廖忠剑【摘要】目的：对应用多层螺旋CT动态增强扫描诊断小肠原发性肿瘤的临床价值进行系统探讨。
方法将通过手术病理及免疫组织化学证实的79例小肠原发性肿瘤的临床诊断资料进行回顾性分析，均在治疗前进行多层螺旋CT动态增强扫描。
结果本组患者中，小肠腺癌37例，平扫表现为肠壁呈不规则、局限性增厚，存在明确的肿块，并伴有肠腔狭窄；增强扫描表现为病灶呈中等不均匀强化。
小肠间质瘤23例，平扫表现为肠襻往肠腔外生长，且呈近似圆形状肿块；增强扫描表现为肿瘤实质期显著强化，并且为延迟强化。
小肠淋巴瘤15例，平扫表现为肠壁为环形增厚；增强扫描表现为动脉期、门脉期呈不均匀强化。
脂肪瘤4例，平扫表现是空肠内有近似圆形低密度肿块；增强扫描无强化。
结论在小肠原发性肿瘤诊断中应用多层螺旋CT动态增强扫描检查，可更为准确的掌握病变部位、肿块大小，并可依照肿瘤强化情况判定肿瘤性质，临床意义重大。

由于小肠肠道迂回、重叠且处于蠕动状态中，在发生肿瘤病变后临床症状、体征很难和一般性病变区分，有较高的误诊率和漏诊率[1]。
以往临床上主要通过X线钡餐造影、内镜等检查，但是很难探查到管壁及管腔外的病变，特异性不佳、诊断准确性不高，在临床确诊上有用性不大[2]。
多层螺旋CT （MSCT）具有分辨率高、容积扫描迅速、后期处理便捷等特点，可更为清楚、全面掌握腔壁厚度、病变状况、清晰显示肠系膜以及肠腔外状况等。
为进一步掌握探究小肠原发性肿瘤的MSCT动态增强扫描诊断情况，本文对79例小肠原发性肿瘤的多层螺旋CT动态增强扫描影像资料进行回顾性，报道如下。
探讨小肠淋巴瘤与小肠腺癌的多层螺旋CT诊断及鉴别诊断李丽【摘要】Objective To study and analyze the clinical diagnosis effect of multi slice spiral CT in patients with small intestinal lymphoma and small intestinal adenocarcinoma. Methods 15 cases of small intestinal lymphoma and 12 cases of small intestinal adenocarcinoma in our hospital were selected and analyzed.ResultsIntestinal adenocarcinoma occurs in the proximal small intestine, the incidence range limitations, mainly involving the intestinal wall and intestinal annular cavity soft tissue nodules lesion enhancement pattern as "rapid rise platform", with liver metastasis and lymph node lesions around the small, pancreatic invasion, intrahepatic and extrahepatic bile duct and dilatation of the pancreatic duct, the three-dimensional angiography (CTA) examination showed"signs of tumorstaining", small intestinal lymphoma occurs in the distal small intestine, the incidence of a wide range of lesion enhancement pattern for "slow rise", with mesentery or retroperitoneal lymph nodes, by angiography (CTA) examination showed the apparent "tumor blood vessels"phenomenon; there are some differences between the test results of two groups (P<0.05), with statistical signiifcance.Conclusion Clinical diagnosis significance of multislice spiral CT scan on cause and condition analysis of small intestinal lymphoma and adenocarcinoma of the small intestine development, and for the characteristics of both in CT and CTA under the change, can be used for clinical diagnosis.%目的：研究分析多层螺旋CT对小肠淋巴瘤以及小肠腺癌患者的临床诊断效果。
CT小肠造影在诊断小肠肿瘤中的应用价值徐莹;陈业媛;舒虹;肖香佐【摘要】目的：探讨多层螺旋CT小肠造影（MSCTE）在小肠肿瘤诊断中的应用价值。
方法回顾性分析经手术病理证实的45例小肠肿瘤的MSCTE影像表现，总结其影像学表现特点。

%Objective To investigate application prospects of Multi-slice computed tomography Enterography(MSCTE) in diag-nosing small intestine tumor (SIT). Methods MSCTE findings were retrospectively analyzed in 45 cases of SIT diagnosed patho-logically after surgery and were summarized in terms of imaging features. Results Of all 45 cases of SIT,9 were benign ones and 6 were lipoma,characterized by low-density mass shadow in intestinal cavity;2 were adenoma,characterized by homogeneous soft tissue mass in intestinal cavity;1 belonged to ileac mesentery lymphangioma,characterized by irregular cyst-like focus;34 were the most common type of malignancies,14 of which wereadenocarcinoma,characterized by localized ring-formed thickening of in-testinal wall with moderate heterogeneous enhancement;11 were mesenchymoma,characterized by soft tissue mass relatively big in measurement,which primarily grew outside the intestinal cavity,with heterogeneous density,moderate or distinct enhancement ac-companied frequently by cystic degeneration and necrosis;9 werelymphoma,characterized by irregular thickening of intestinal wall or formation of soft tissue mass,which affected intestine in relatively greater length,and which took on homogeneous slight-moder-ate enhancement accompanied frequently by enlargement of retroperitoneal lymph nodes and those in mesentery. 2 were rare ma-lignancies and 1 was metastatic tumor,characterized by multiple irregular chickening of intestinal wall with distinct enhancement and presence of metastatic nodules in abdominal wall;1 was carcinoid tumor characterized by irregular mass in right lower quad-rant. Conclusion It suggests that MSCTE has good prospects of clinical application in diagnosis and differential diagnosis of SIT.【期刊名称】《江西医药》【年(卷),期】2015(000)005【总页数】4页(P387-390)【关键词】小肠肿瘤;多层螺旋CT小肠造影【作者】徐莹;陈业媛;舒虹;肖香佐【作者单位】南昌大学第一附属医院影像科，南昌 330006;南昌大学第一附属医院影像科，南昌 330006;南昌大学第一附属医院影像科，南昌 330006;南昌大学第一附属医院影像科，南昌 330006【正文语种】中文【中图分类】R816.5原发性小肠肿瘤发病率较低，仅占所有胃肠道肿瘤的3%-6%[1]。
