Plug-and-play advanced magnetic resonance spectroscopy.

ABSTRACT:

Purpose

Advanced MRS protocols improve data quality and reproducibility relative to vendor-provided protocols; however, they are challenging to incorporate into the clinical workflow and require local MRS expertise for successful implementation. Here, we developed an automated advanced MRS acquisition protocol at 3T to facilitate acquisition of high-quality spectroscopic data without local MRS expertise.

Methods

First, a B₀ shimming protocol was selected for automation by comparing 3 widely used B₀ algorithms (2 vendor protocols and FAST(EST)MAP). Next, voxel-based B₀ and B₁ calibrations were incorporated into the consensus-recommended semi-LASER sequence and combined with an automated VOI prescription tool, a recently developed me
