背景情况:
- 异常的循环运动模式 (CMPs) 与结肠功能障碍有关.
- 高分辨率结肠力度计 (HRCM) 是CMP评估的当前标准,但成本昂贵且难以获得.
- 需要一种经过验证的,非侵入性的方法来评估结肠运动性.
研究的目的:
- 通过直接比较其结果与HRCM来验证体表面结肠映射 (BSCM).
- 在评估结肠运动活动时,确定BSCM和HRCM之间的时空相关性.
主要方法:

This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...

The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:
