The demonstration of secretory gastric mucosa in Meckel's diverticulum of the ileum in patients undergoing radionuclide imaging with 99mTc sodium pertechnetate is greatly improved with the prior administration of cimetidine. This results in enhanced accumulation of pertechnetate in the gastric mucosa along with reduced excretion of the radionuclide into the gastric lumen and, consequently, less intestinal radioactivity.
对于接受过高锝酸钠99mTc放射性核素成像的患者，在回肠梅克尔憩室中显示分泌性胃黏膜的情况，通过预先给予西咪替丁可得到极大改善。这会使高锝酸盐在胃黏膜中的蓄积增强，同时减少放射性核素向胃腔内的排泄，从而减少肠道放射性。
