1 From the Department of Radiology, University of Bonn, Sigmund-Freud-Strasse 25, D-53105 Bonn, Germany (P.M., S.F., F.T., H.H.S.); and Philips Medical Systems, Best, the Netherlands (J.S.B., J.G.). Received June 27, 2001; revision requested August 16; revision received October 24; accepted December 10. P.M. supported by a BONFOR grant from the Medical Department of the University of Bonn.

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.
