Water-fat Dixon cardiac magnetic resonance fingerprinting.

ABSTRACT:

Purpose

Cardiac magnetic resonance fingerprinting (cMRF) has been recently introduced to simultaneously provide T₁ , T₂ , and M₀ maps. Here, we develop a 3-point Dixon-cMRF approach to enable simultaneous water specific T₁ , T₂ , and M₀ mapping of the heart and fat fraction (FF) estimation in a single breath-hold scan.

Methods

Dixon-cMRF is achieved by combining cMRF with several innovations that were previously introduced for other applications, including a 3-echo GRE acquisition with golden angle radial readout and a high-dimensional low-rank tensor constrained reconstruction to recover the highly undersampled time series images for each echo. Water-fat separation of the Dixon-cMRF time series is performed t
