MOTION TRIGGERED MR IMAGING USING APT/CEST

摘要

The invention relates to a method of MR imaging of a moving portion of a body ( 10 ) the method comprising the steps of: detecting a motion signal (MS) from the body ( 10 ) while continuously subjecting the portion of the body ( 10 ) to one or more preparation RF pulses; subjecting the portion of the body ( 10 ) to an imaging sequence comprising at least one excitation RF pulse and switched magnetic field gradients wherein the imaging sequence is triggered by the detected motion signal (MS); acquiring MR signals from the portion of the body ( 10 ); and reconstructing a MR image from the acquired MR signals.
