用高速平面回波成像技术：模数闪烁平面回波单脉冲技术（MBEST）对4名志愿者的胃肠道运动进行了描述。64和128毫秒的数据采集时间，消除了由于运动引起的图像退化，而无需肠麻痹，并允许真实的胃肠道成像。描绘了空腹和进食受试者以及受试者中胃窦和近端小肠的蠕动模式。这种新技术的潜在的定量测量胃肠道运动被证明。
Gastrointestinal (GI) tract motility was depicted in four human volunteers with the high-speed echo-planar imaging technique: modulus blipped echo-planar single-pulse technique (MBEST). Data acquisition times of 64 and 128 msec obviate image degradation due to motion without the need for gut paralysis and allow imaging of the GI tract in real time. Peristaltic patterns of the gastric antrum and proximal small intestine were depicted for fasting and fed subjects and subjects in whom peristalsis had been pharmacologically stimulated. The potential for quantitative measurements of GI tract motion with this new technique was demonstrated.
