Multicompartment Magnetic Resonance Fingerprinting
Magnetic resonance fingerprinting (MRF) is a technique for quantitative estimation of spinrelaxation parameters from magnetic-resonance data. Most current MRF approaches assume that only one tissue is present in each voxel, which neglects the tissue’s microstructure, and may lead to artifacts in the recovered parameter maps at boundaries between tissues. In this work, we propose a multicompartm...
متن کاملMagnetic resonance fingerprinting (MRF)
Understanding the need Quantitative vs Qualitative MRI data: The vast majority of common clinical MRI protocols rely on qualitative images reflecting the weighted effect of different tissue parameters. These contrast parameters include relaxation times, principally T1, T2 and T2*, as well as structural or functional quantities such as diffusion and blood flow. The absolute level of the signal v...
متن کاملMagnetic Resonance Fingerprinting by exploiting Low Rank
Magnetic Resonance Fingerprinting (MRF) is a relatively new approach that provides quantitative MRI measures using randomized acquisition. Extraction of physical quantitative tissue parameters is performed off-line, based on acquisition with varying parameters and a dictionary generated according to the Bloch equations. MRF uses hundreds of radio frequency (RF) excitation pulses for acquisition...
متن کاملA Compressed Sensing Framework for Magnetic Resonance Fingerprinting
Inspired by the recently proposed Magnetic Resonance Fingerprinting (MRF) technique, we develop a principled compressed sensing framework for quantitative MRI. The three key components are: a random pulse excitation sequence following the MRF technique; a random EPI subsampling strategy and an iterative projection algorithm that imposes consistency with the Bloch equations. We show that theoret...
