1. A magnetic resonance imaging (MRI) system comprising: an MRI gantry having static and gradient magnet assemblies and at least one radio frequency (RF) coil defining an image volume into which a patient region of interest (ROI) can be disposed; MRI control circuits connected to control components within said MRI gantry and configured to effect MRI data acquisition sequences of RF and gradient magnetic pulses which elicit MRI signals from patient tissue when an ROT is disposed therein, to acquire and process said elicited MRI signals into MR image data; said MRI control circuits being configured to (a) acquire k-space data for a patient ROI during an MRI data acquisition sequence including a nuclear magnetic resonance (NMR) signal readout period, said data acquisition sequence using at least one fat-specific RF NMR magnetization inversion pulse and at least one water-specific RF NMR magnetization inversion pulse imposed prior to said readout period, said inversion pulses each being respectively timed to cause a substantial null in NMR magnetization of normal tissue protons and of fat tissue protons during said readout period when MRI data for a center portion of k-space is being acquired; (b) process such acquired k-space data into MR image data in the spatial domain; and (c) store, transfer and/or display said MR image data representing a contrast enhanced image of tissues within the ROI but having substantially suppressed normal and fat nuclei components therein.
