Overview
Gastric emptying scintigraphy may be helpful in the diagnosis of gastroparesis. Findings include delayed gastric emptying of food on X-ray.
Other Imaging Findings
Gastric Emptying Scintigraphy
- Gastric Emptying Scintigraphy is considered as a gold standard of gastroparesis.[1][2]
- The method for this test is eating a low-fat, egg-white meal followed by repeated scan to measure the rate of gastric emptying at 0, 1, 2, and 4 hours.
- The delayed gastric emptying would be confirmed, if there is:
- 90% gastric retention at 1 hour
- 60% at 2 hours (greater accuracy for detecting accelerated gastric emptying)
- 10% at 4 hours (higher accuracy for detecting slow gastric emptying)
- Factors that might affect on the results of gastric emptying studies include:
- Medications that slow down the gastric emptying:
- Tobacco smoking
- Hyperglycemia
- The advantages of gastric Emptying Scintigraphy include:
- Noninvasive
- Quantitative
