Abstract

This paper presents a novel method for phase sensitive inversion recovery (PSIR) imaging for improved T1 contrast. This method models the phase of the complex magnetic resonance image using a statistical model based on Markov Random Fields. A computationally efficient optimization method is developed. Computer simulations and in-vivo brain imaging experiments show that the proposed method can produce PSIR images with enhanced T1 contrast and it is robust against high levels of data noise even when rapid phase variations are presented.
