Gastric scintigraphy. The test consisted of an exploration of both the solid (ovalbumin with ^99mTc-labeled colloids) and the liquid (¹¹¹In diethylene triamine pentaacetic acid diluted in water) phases of gastric emptying (left panel for liquids and right panel for solids). The parameters used for the result interpretation were the half-time emptying (T1/2) and the residual activity at 4 hours (activity/time curves for liquid and solid). In this case, there was a very slow and gradual reduction of the tracer in the stomach. The residual activity remains very high 4 hours after ingestion: 30% at 4 hours (N< 10%) for liquid, and 77% (N< 10%) for solids
