Abstract Objective: To analyse and evaluate local invasion of gastric carcinoma by 16-slices spiral-CT. Methods: Twenty-seven patients with gastric carcinoma were scanned by 16-slices spiral-CT including plain scans and dual phase enhanced scans. Local invasion was assessed by using the transaxial scans and combining with the post-processing scans, then SCT findings were correlated with surgrical-pathologic staging. Results: Two patients with early stage of gastric carcinoma were missed on transaxial scans. The accuracy rate of judging local invasion was 63%. Combining the post-processing scans, there was no misdiagnosing case. The accuracy rate was 85.3%. Conclusion: The enhancing scan of 16-slices spiral-CT combining with reconstruction technique can improve the detection rate of small lesions, and it is reliable for judgement of invasion in stomach wall and peripheral infiltration, so that 16-slices spiral-CT can judge the local invasion of gastric carcinoma fairly well.
