Abstract
Methods and systems for using magnetic resonance (MR) imaging include obtaining a T1-weighted MR image and a proton-density (PD) weighted MR image from a dual-image acquisition following an inversion-recovery (IR) pulse. The T1-weighted and PD-weighted images are used to obtain a polarity function describing a positive or negative polarity at individual voxels, which is used to reconstruct a polarity-enhanced PD-weighted image from the PD-weighted image. The polarity-enhanced PD-weighted image can be used for assessing at least plaque burden and juxtaluminal calcification (JCA).
