胃壁增厚的CT研究及应用价值

Evaluation of CT in gastric wall thickening

目的提高CT对于引起胃壁增厚的胃部病变的诊断及应用价值重要性的认识。方法回顾性分析经手术病理及胃镜病理证实的82例胃壁增厚患者CT表现,并与正常胃壁厚度相比较,从胃壁增厚的程度、形态等来诊断及鉴别胃壁增厚的病变。结果 82例胃部疾病,其中胃癌45例、胃淋巴瘤17例、间质瘤12例、胃炎8例,累及范围共122处;其中胃窦部56处,平均厚度(19.3+11.8)mm;胃体部45处,平均厚度(32.6+12.3)mm;胃底贲门部21处,平均厚度(39.1+7.5)mm;与正常各区胃壁厚度有显著性差异。本组82例病例胃壁增厚的CT类型:条形或梭形增厚(30)、肿块形增厚(14)、结节形增厚(5)、溃疡型增厚(10)、不规则形增厚(8)、混合型增厚(15)等。结论 CT对于胃壁增厚的厚度、形态等的观察有很大的价值,能够较好地准确诊断胃壁增厚的相关疾病及鉴别诊断。

Objective To explore the CT findings and differential diagnosis of gastric wall thickening.Methods The CT findings of 82 cases of gastric lesions confirmed by operation and pathology were analyzed retrospectively,compared with normal gastric wall thickness. Based on the extent of gastric wall thickness,morphology the characteristics of the CT findings were identified.Results Of the 82 cases 45 were with gastric carcinoma,17 with gastric lymphoma,12 with gastric stromal tumor,8 with gastritis. 82 cases with gastric wall thickening were divided into seven groups:group 1banding type(30),group 2 mass type(14),group3 nodular type(5),group 4 ulcerative type(10),group 5 irregular type(8),group 6 coral type(0),group 7 mixed type(15). Conclusion CT findings of gastric wall thickening has important value in diagnosis of gastric lesions. On basis of the extent of gastric wall thickening,morphology imaging diagnosis and differential diagnosis of gastric lesions can be improved.
