Scintigraphy technique is considered the gold standard for gastric emptying evaluations. Lately mechanical magnetogastrography (MMG) technique has emerged as an alternative for these assessments. This study presents the determination of reference values for MMG in order to validate this novel technique in gastric emptying measurements. Both methodologies were used in young and healthy subjects provided with a solid test meal. The measurements were performed with 2 days of difference. Bland-Altman analysis of the data was performed to conclude about the feasibility of MMG as a good alternative test for gastric emptying assessments. Using MMG, an average of the gastric emptying half-time of 57.6 +/- 25.8 min was obtained, whereas the same parameter obtained by scintigraphy was 52.2 +/- 12.9 min. In conclusion, the use of MMG technique is in concordance with the results using the gold standard technique for gastric emptying measurements.
闪烁扫描技术被认为是胃排空评估的金标准。最近，机械磁胃动力描记术（MMG）技术已经成为这些评估的替代方法。本研究旨在确定 MMG 的参考值，以验证该新技术在胃排空测量中的应用。这两种方法都用于提供固体测试餐的年轻和健康受试者。测量在 2 天内进行。对数据进行 Bland-Altman 分析，以得出 MMG 作为胃排空评估的良好替代测试的可行性结论。使用 MMG，获得的胃排空半时间平均值为 57.6 +/- 25.8 分钟，而闪烁扫描技术获得的相同参数为 52.2 +/- 12.9 分钟。总之，MMG 技术的使用与胃排空测量的金标准技术的结果一致。
