Multichannel intraluminal impedance is a relatively new technology that allows detection of bolus movement in the gastrointestinal tract without the use of radiation. In clinical applications it is combined with manometry, allowing a better evaluation of the functional characteristics (ie, bolus transit) of esophageal motility abnormalities. When combined with pH monitoring, it provides more comprehensive data on both acid and nonacid gastroesophageal reflux.
多通道腔内阻抗是一项相对较新的技术，可在不使用辐射的情况下检测胃肠道中的团块运动。在临床应用中，它与测压法相结合，能更好地评估食管动力异常的功能特征（即团块传输）。当与pH监测相结合时，它能提供关于酸性和非酸性胃食管反流的更全面数据。
