Simultaneous markers for fluid and solid gastric emptying: new variations on an old theme: concise communication.
Radiotracer techniques for the assessment of gastric emptying have become popular in the past 6 yr. A new double-nuclide technique, for the simultaneous tagging of the solid and fluid phases, is described. Technetium-99m sulfur colloid (Tc-99m SC) is used in a manner similar to that described by Meyer and colleagues, but the new technique does not involve the use of live chickens, a significant advantage over the earlier procedures. Several fluid-phase radionuclides were tested to be used in conjunction with the Tc-99m SC. Indium-111 DTPA was found to be the only compatible fluid-phase agent. This new double-tracer technique promises to be safe, economical, simple, and physiologically sound.
