Abstract

Prospective study of lymph node imaging of twenty stomach cancer cases with dissected lymph nodes being injected into the submucosa layer of stomach under surgical field was done. Total dose of 5 mci in 5 cc of volume was injected along the multiple sites of the lesser and greater curvature of stomach and collected lymph nodes within 2 hour of surgical time were placed under gamma camera and lymph node imagings were obtained. Pathological invasion of tumor and correlation of cold defect or hot uptake was compared each other. Tumor invasion of nodes revealed cold defect area which was correlated well with the pathological specimen. Correlation rate was 84.6%. We are planning to extend these procedures and trying endoscopic injection of positive imgaing agents such as Ga-73-3 Ig 2 alpha in future.
