Accelerated parameter mapping with compressed sensing: an alternative to MR Fingerprinting
PA Gómez, G Buonincontri… - Proc Intl Soc Mag …, 2017 - mediatum.ub.tum.de
We introduce a method for MR parameter mapping based on three concepts: 1) an inversion
recovery, variable flip angle acquisition strategy designed for speed, signal, and contrast; 2)
a compressed sensing reconstruction which exploits spatiotemporal correlations through
low rank regularization; and 3) a model-based optimization to simultaneously estimate
proton density, T1, and T2 values from the acquired measurements. Compared to MR
Fingerprinting, the proposed method achieves a five-fold acc...»
