目的:确定CT鉴别良恶性胃壁增厚的敏感性和特异性.方法:在螺旋CT和数字胃肠光盘中收集到40例螺旋CT见胃壁增厚,且在作CT检查前或后4wk内作过钡餐检查的患者.复习其CT表现,并以胃壁增厚的程度、对称度、分布和强化等特点确定CT发现恶性胃壁增厚的敏感性和特异性.结果:最后诊断胃炎20例、食道裂孔疝4例、良性溃疡3例、良性肿瘤3例、恶性胃肿瘤8例、正常2例.40例胃壁平均厚度14mm(7-65mm).胃壁厚度≥10mm诊断恶性肿瘤的敏感度100%,特异性为43%,而局限性、偏心性、强化型胃壁增厚的敏感度分别为93%、71%、43%,特异性为8%、75%、88%.综合≥10mm的胃壁增厚,且呈局限性、偏心性、强化者,其敏感性为36%,特异性上升到92%.结论:综合胃壁增厚呈局限性、偏心性且有强化等特点,则诊断恶性胃壁增厚的特异性可上升到92%.因此,这些患者须在近期内作进一步检查.
OBJECTIVE: To determine the sensitivity and specificity of CT in differential diagnosis of benign and malignant gastric walls.Methods: 40 cases of helical CT were collected in spiral CT and digital gastrointestinal discs, The patients with barium meal examination were reviewed and their CT findings were reviewed.The sensitivity and specificity of CT findings of malignant gastric wall thickening were determined by the degree of gastric thickening, symmetry, distribution and enhancement.Results: The final diagnosis of gastritis in 20 cases, esophagus 4 cases of hiatal hernia, 3 cases of benign ulcer, 3 cases of benign tumor, 8 cases of malignant gastric tumor, 2 cases of normal.The average thickness of gastric wall 14mm (7-65mm) .The gastric wall thickness≥10mm sensitivity of 100% Specificity of 43%, and limitations, eccentricity, enhanced sensitivity of gastric wall thickening were 93%, 71%, 43%, specificity of 8%, 75%, 88% The sensitivity, specificity and sensitivity were 36% and 92%, respectively.Conclusion: The comprehensive gastric wall thickening is characterized by limitations, eccentricity and enhancement, so the diagnosis of malignant gastric wall increased Thickness can rise to 92%, so these patients should be further examined in the near future.
