| Abstract |
Scintigraphic measurement of gastric emptying time has
been reported to be influenced by the variation in
depth of radionuclide within the stomach. In order to
determine the effect of tissue attenuation in the
measurement of gastric emptying time, 15 gastric
emptying studies were performed with Tc-99m labeled egg
sandwiches. Single anterior detector method
overestimated the T1/2 by an average of 13% than
geometric mean method and the range of overestimation
was wide (from -13% to +32%). Therefore, to evaluate
the gastric empthying time accurately, methods of
attenuation correction are needed. |
