摘要
目的 评价螺旋CT三期增强扫描对胃癌浸润及转移的准确性,并探讨影像学与病理学的内在联系。资料与方法 对46例胃癌患者行螺旋CT三期增强扫描并与术后病理对照。结果 (1)螺旋CT诊断浆膜受侵、淋巴结转移和远处转移的准确性分别为84.8％、87.0％和100％。(2)螺旋CT征象中浆膜侵犯、淋巴结转移和远处转移均与其病理特征密切相关(P<0.05)。结论 螺旋CT三期增强扫描能较全面、准确地反映胃癌病理特征,是诊断胃癌浸润及转移的可靠影像学方法。
Objective To determine the accuracy of triphasic enhanced helical CT scanning in judging the invasion and metastasis of gastric carcinoma, and to discuss the relation between imaging signs and pathologic findings. Materials and Methods Triphasic enhanced helical CT scanning was performed in 46 patients with gastric carcinoma. Imaging findings were compared with post - operative pathologic results. Results (1) The accuracy of helical CT for diagnosing involvement of tunica serosa, lymph node metastasis and distant metastasis was 84.8% , 87.0% and 100% , respectively. (2) CT signs of serosal involvement, lymph node metastasis and distant metastasis were in good accordance with pathological findings ( P < 0.05) . Conclusion Triphasic enhanced helical CT scans can comprehensively and precisely reflect the pathologic characteristics of gastric carcinoma, thus, it is a reliable technique for the diagnosis of the disease.
