Abstract:
1. An MR (Magnetic Resonance) imaging system for independently manipulating a fat and a water component of MR signals used for generating image data, comprising: an RF (Radio Frequency) signal generator and a magnetic field gradient generator for providing an RF pulse and magnetic field gradient sequence for acquisition of an MR signal discriminating between anatomical objects based on longitudinal relaxation time (T1), said RF pulse and magnetic field gradient sequence comprising: an image data processor for processing the acquired MR signal to provide a display image with enhanced visualization of discriminated anatomical elements, wherein said first pulse sequence includes a frequency non-selective inversion recovery RF pulse inverting an MR signal from both water and fat, and a fat selective inversion recovery RF pulse having a resonant frequency selected to invert a fat component of the MR signal substantially exclusively of water, and wherein said fat selective inversion recovery RF pulse is provided substantially immediately preceding or following said non-selective inversion recovery RF pulse, leaving a fat signal component of the MR signal substantially unchanged.
