Synopsis

Keywords: MR Fingerprinting/Synthetic MR, CardiovascularThis work describes a pipeline for fully inline generation of T₁, T₂ and extracellular volume (ECV) maps from cardiac Magnetic Resonance Fingerprinting (MRF) data. Reconstruction of multi-parametric tissue property maps using cardiac MRF have recently been made possible directly on the scanner by replacing the need to perform Bloch equation simulations with a neural network. MRF-derived T₁, T₂ and ECV values were acquired and compared to MOLLI and T₂p-SSFP in 5 successive clinical patients.
