Abstract
A normal meal can be labelled with 99mtechnetium, e.g. as 99mTc-diethylene-triamine-pentacetic acid (DTPA). The supine patient is scanned half-hourly after this has been consumed, till activity has left the stomach. Emptying is exponential, so the half-life of meals in the stomach is a useful measurement. This is normally 60–90 min, compared with 40–60 min in uncomplicated duodenal ulcers and 75–100+ min in duodenal ulcers with gastric outflow obstruction.
