Overview
Gastric emptying scintigraphy is considered as a gold standard of gastroparesis. Delayed gastric emptying is confirmed by 10% gastric retention at 4 hours. Factors that affect the results of this test include medications, tobacco smoking, and hyperglycemia.
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 scans to measure the rate of gastric emptying at 0, 1, 2, and 4 hours.
- The delayed gastric emptying would be confirmed, if there is:
- 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
- Accurate
- Sensitive
- specific
