Evaluation of ~(18)F-FDG hPET/CT in primary carcinoma of gastric cardia / 中国癌症杂志

ABSTRACT

Background and Purpose:dPET/CT is very expensive,so although the accuracy of hPET/CT is less than dPET/CT,it is better than CT,and is useful for guiding the tumor staging before operation.This paper is evaluate the role of ~(18)F-fluorodeoxyglucose(FDG) hPET/CT in primary carcinoma of gastric cardia detection.Methods:26 patients with histologically proven primary carcinoma of gastric cardia underwent whole body hPET/CT imaging.Visual and semiquantitative analysis and standardized uptake value(SUV) were used to analyze the images.The results of hPET/CT study were compared with those of CT.Results:1.The sensitivity of hPET/CT in primary carcinoma of gastric cardia detection was 92.3%(24/26);two cases of signet ring cell carcinoma gave false negative results,and the primary lesions were small(
