摘要
To determine the accuracy of triphase enhanced helical CT in judging the invasion and metastasis of gastric carcinoma, and to discuss the relation between imaging signs and pathological findings. Methods: Triphase enhanced helical CT scanning was performed in 46 patients with gastric carcinoma. Imaging findings were compared with postoperative 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: Triphase 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 this disease.
