title: The role of kidney uptake of Tc-99m pertechnetate during quantitation of gastric scintigraphy.
abstract: It is shown that during quantitative gastric scintigraphy with Tc-99m pertechnetate significant errors may occur if kidney uptake is ignored. The magnitude of the error was assessed in 12 patients, and could lead to an over-estimation of gastric uptake by up to 20%.
