Diagnosis of Stomach Carcinoma by Radioisotope Scanning

Scanning of the stomach after administration of 131I and 99mTc is presented. Experiments on 20 dogs were performed and 105 patients were examined. The studies with 131I are only mentioned briefly as they have been summarized in a previous publication and we have concentrated on our experience with 99mTc and on stomach carcinoma. The turnover of the nuclide in blood, urine, gastric juice and gastric mucosa was tested: in-vivo and post-operative scannings were performed. The scans are classified in four groups. Carcinoma of the stomach results in space-occupying lesions or foggy scans. A correlation of 85 - 90% between scan results and clinical findings is noted. A special group of 10 volunteers was examined to establish the possibility of a screening examination for the detection of stomach cancer using the technique presented. (author)
