Solid Gastric Emptying

24 year old male, for pre-operative anti-reflux surgery.
In sequential images every 15 minutes note  appropriate movement of the radiotracer toward the duodenum and then across the intestine.
Little activity is observed in the stomach at 120 minutes. The emptying curve was linear with one phase. Mean half-time 64  min.
Gastric retention:
At 60 minutes was 53% (NV: 38 - 85%)
At 90 minutes was 30% (NV: 6.3 to 76.3%)
At 120 minutes was 7% (NV: 0 - 62%)

Gastrointestinal scintigraphy is an integral and important component of the assessment of gastrointestinal function. Gastric emptying scintigraphy is established in clinical practice and research the "gold standard" to assess gastric emptying.
