在12名健康志愿者的腹部进行磁共振（MR）扩散测量，通过使用扩散加权单激发序列无和脉冲触发不同的触发延迟。脉冲触发至心脏舒张期可减少扩散加权MR图像上的运动伪影，并显着提高腹部器官表观扩散系数（ADC）测量的准确性和可重复性。(C)RSNA，2002年。
Magnetic resonance (MR) diffusion measurements of the abdomen were performed in 12 healthy volunteers by using a diffusion-weighted single-shot sequence both without and with pulse triggering for different trigger delays. Pulse triggering to the diastolic heart phase led to reduced motion artifacts on the diffusion-weighted MR images and to significantly improved accuracy and reproducibility of measurements of the apparent diffusion coefficients, or ADCs, of abdominal organs.
