PULSE SEQUENCE METHOD FOR MRI

摘要

The present invention describes a method for magnetic resonance (MR) and/or MR imaging comprising acquisition of signals and MR images originating from a RF and gradient sequence causing isotropic diffusion weighting of signal attenuation wherein the isotropic diffusion weighting is achieved by one time dependent dephasing vector q(t)having an orientation wherein the isotropic diffusion weighting is proportional to the trace of a diffusion tensor D and wherein the orientation of the time dependent dephasing vector q() is either varied discretely in more than three directions in total or changed continuously or changed in a combination of discretely and continuously during the gradient pulse sequence 0 = = echo time where represents the time. The method may be performed during a single shot (single MR excitation).
