Simultaneous proton magnetic resonance fingerprinting and sodium MRI.

ABSTRACT:

Purpose

The goal of this work is to demonstrate a method for the simultaneous acquisition of proton multiparametric maps (T₁ , T₂ , and proton density) and sodium density images in 1 single scan. We hope that the development of such capabilities will help to ease the implementation of sodium MRI in clinical trials and provide more opportunities for researchers to investigate metabolism through sodium MRI.

Methods

We developed a sequence based on magnetic resonance fingerprinting (MRF), which contains interleaved proton (¹ H) and sodium (²³ Na) excitations followed by a simultaneous center-out radial readout for both nuclei. The receive chain of a 7T scanner was modified to enable simultaneous acquisition of ¹ H and
