摘　　要：目的:观察分析56例不同病理类型胃肿瘤的多排螺旋CT(multi-slice spiral computed tomography,MSCT)表现,提高对胃肿瘤的诊断与鉴别诊断能力.方法:收集本院2011-01/2012-12收治的胃肿瘤病例56例,均作MSCT平扫及双期增强扫描,以病理结果为诊断依据,比较不同病理类型肿瘤的MSCT表现,归纳强化特点.结果:本组56例胃肿瘤病例,病理结果分别为腺癌、间质瘤、淋巴瘤、神经内分泌癌、肝样腺癌,以腺癌最多见(48/56).间质瘤腔内、外生长,腺癌、淋巴瘤及神经内分泌癌、肝样腺癌腔内生长.而在MSCT表现(病灶形态及强化方式、程度)上,本组其他各型肿瘤与腺癌均有相似之处.结论:通过对生长方式、MSCT表现特别是增强特点的观察,能够丰富诊断胃肿瘤的思路,加深对不同病理类型胃肿瘤的认识,进一步提高诊断水平.AIM： To analyze the multi-slice spiral computed tomography （MSCT） features of different pathological types of gastric tumors to improve their diagnosis and differential diagnosis. METHODS： Imaging and pathological data for 56 patients with gastric tumors who underwent MSCT dual-phase enhanced scan were reviewed retrospectively. The MSCT features and enhancement characteristics were compared among different pathological types of gastric tumors. RESULTS： The pathological types of 56 cases of gastric tumors included adenocarcinoma （n= 48）, mesenchymal tumor （n=4）, lymphoma （n=2）, neuroendocrine carcinoma （n=1）, and hepatoid adenocarcinoma （n=1）. Mesenchymal tumors showed specific growth pattern. MSCT enhancement manifestations of various types of gastric tumors were similar. CONCLUSION： Observation of tumor growth pattern and enhancement manifestations by MSCT allows for improvement of the diagnostic accuracy of gastric tumors.
