Across-vendor standardization of semi-LASER for single-voxel MRS at 3T.

ABSTRACT: The semi-adiabatic localization by adiabatic selective refocusing (sLASER) sequence provides single-shot full intensity signal with clean localization and minimal chemical shift displacement error and was recommended by the international MRS Consensus Group as the preferred localization sequence at high- and ultra-high fields. Across-vendor standardization of the sLASER sequence at 3 tesla has been challenging due to the B₁ requirements of the adiabatic inversion pulses and maximum B₁ limitations on some platforms. The aims of this study were to design a short-echo sLASER sequence that can be executed within a B₁ limit of 15 μT by taking advantage of gradient-modulated RF pulses, to implement it on three major platforms and to evaluate the between-vendor re
