Abstract:
A method of imaging diffusion parameters of a body by means of magnetic resonance (MR) including:generating an imaging pulse sequence comprisinggenerating an excitation RF pulse,generating a magnetization preparation pulse sequence for adjusting a magnetization preparation,generating an additional RF pulse in order to eliminate a non-Meibohm-Gill (MG) component,generating refocusing RF pulses, andapplying first and second crusher magnetic field gradients in order to measure position-dependent MR signals, andgenerating an adjustment pulse sequence comprisinggenerating a preparatory excitation RF pulse,applying a preparatory magnetization preparation pulse sequence,generating a preparatory additional RF pulse in order to select an MG component,generating preparatory refocusing RF pulses,applying first and second preparatory crusher magnetic field gradients, andmeasuring preparatory magnetic resonance signals,wherein the additional RF pulse in the imaging pulse sequence is adjusted in dependence on a parameter which is determined from the preparatory MR signals measured in the adjustment pulse sequence.
