In clinical practice, bowel sounds are often used to assess bowel motility. However, the diagnosis differs depending on the literature because diagnoses have been based on empirically established criteria. To establish diagnostic criteria, researching the mechanism of bowel-sound occurrence is necessary. In this study, based on simultaneously measured X-ray fluoroscopy and bowel sounds, correlation and Granger causality among bowel movement, luminal content movement, and abdominal sound were estimated. The results supported our hypothesis that the bowel moves luminal contents and luminal contents generate abdominal sounds.
在临床实践中，肠鸣音通常用于评估肠道蠕动。然而，由于诊断是基于经验建立的标准，因此在文献中有所不同。为了建立诊断标准，有必要研究肠鸣音发生的机制。在这项研究中，基于同时测量的 X 射线透视和肠鸣音，估计了肠道运动、腔内容物运动和腹部声音之间的相关性和格兰杰因果关系。结果支持了我们的假设，即肠道移动腔内容物，腔内容物产生腹部声音。
