How is gastroparesis diagnosed using a radioisotope gastric-emptying scan (gastric scintigraphy)?

ANSWER

You eat food that contains a small amount of radioisotope (a radioactive substance), then lie under a scanning machine; if the scan shows that more than 10% of food is still in your stomach four hours after eating, you are diagnosed with gastroparesis.
