Methods: A technologist training session emphasized the importance of thorough mixing of 99mTc-sulfur colloid in the egg meal. For 6 mo after training, an image of the prepared mixed egg was acquired before patient ingestion. Consecutive gastric-emptying studies performed 6 mo before and after training were reviewed by 2 experienced physicians. Results: There were 7 abnormal and 44 normal studies before and 15 abnormal and 29 normal studies after training (P < 0.05). Subjective evaluations of images for meal-mixing quality by 2 readers correlated with each other and with an objective measure of expected gastric-emptying physiology (correlation coefficients, 0.54 and 0.38, respectively). Conclusion: The described clinical intervention improved the accuracy of our gastric-emptying studies by decreasing false-negative studies. %U https://tech.snmjournals.org/content/jnmt/42/4/274.full.pdf
