摘　　要：目的探讨螺旋CT双期扫描在胃肠道肿瘤诊断及分期中的价值。方法回顾性分析经手术病理证实的69例胃肠道肿瘤螺旋CT双期扫描的表现及分期。结果(1)69例胃肠道肿瘤,55例以门静脉期强化程度为著,与动脉期比较有显著性差异(P<0.05);(2)69例胃肠道肿瘤的双期扫描的T分期准确率为87%;(3)动脉期对转移性淋巴结的敏感度为70.4%、特异度为62.6%,静脉期敏感度为82.9%、特异度为80.2%。结论螺旋CT双期扫描是胃肠道肿瘤术前检查重要手段。Objective To investigate the clinical value of helical CT dual -phase scan in diagnosis and staging in gastrointestinal tumor. Methods Helical CT dual - phase enhanced imaging features of gastrointestinal tumor proved by surgery and pathology in 69 cases were retrospectively reviewed. Results （1） The tumors in 55 cases were enhanced ovviously in the venous phase compared with that in arterial phase （ P 〈 0.05 ） ; （2） The accuracy of T staging was 87% with helical CT dual - phase enhancement ; （3 ） In displaying lymphatic metastasis ,the sensitivity and specificity were 70.4% and 62.6% with arterial phase ,82.9% and 80.2% with venous phase respectively. Conclusion Before surgical operation, helical CT dual - phase enhancement is a meaningful way to check the patients with gastrointestinal tumor.
