Technetium 99m-DTPA microcapsules: a new preparation for gastric emptying studies.
Technetium 99m-DTPA microcapsules have been developed to measure gastric emptying. Such capsules not only provide high labeling efficiency in vitro, but demonstrate limited dissociation in vivo, resulting in decreased error during measurement. In normal control subjects, the half-life ranged from 40 to 80 minutes under the aforementioned conditions.
