Summary
New method of differential diagnosis of gastric cancer was reported. After intravenous32P administration, lesion was counted by small catheter-type radiation detector system under gastrofiberscopic direct vision control.
Optimum counting time was examined in man and it was found to be between 20 to 50 hours after intravenous administration of32P.
Under the currently available technology of miniature detector, still β-emitting carcinophilic agent was found to be the agent of choice to this end, since γ-emitting carcinophilic agents can not provide data originated only from the gastric mucosa in question.
