摘　　要：目的探讨PET/CT检查在胃癌诊断中的应用价值与局限性。方法回顾性分析34例具有胃癌影像或临床特征的全身PET/CT资料,并与胃镜病理及随访结果对照。结果病理显示其中胃癌24例,胃部炎性反应4例,正常6例;PET/CT对胃癌诊断的敏感性为91.7%(22/24),准确率64.7%(22/34)。结论PET/CT检查在胃癌的诊断中具有很高敏感性,但存在一定的假阳性,需要引起临床医师足够的重视。Objective To study the value and limitation of PET/CT in the diagnosis of gastric cancer. Methods Thirty - four＇ patients with positive results of stomach cancer or suspected clinically underwent whole body ^18F - FDG PET/CT examination. These obtained data were reviewed retrospectively and compared with endogastroscopic, pathologic and follow - up results. Results Of all the 34 patients, 32 were diagnosed as having gastric cancer, 2 patients were missed for their unspecific changes. Finally, 24 cases of gastric cancer, 4 cases of gastritis and 6 cases of normal variants were confirmed by pathology. The sensitivity of PET/CT in the diagnosis of gastric cancer was 91.7% （22/24）, and its accuracy was 64.7% （22/34）. Conclusions PET/CT has high sensitivity on the detection of early gastric cancer,but false - positive results exist; so we should be alert in evaluation of PET/CT.
