Short TE 1H CSI with Fully Excited VOI – circumventing challenges at 3T

Purpose: Spectroscopy at 3T can benefit from the increased signal to noise ratio and the increased spectral resolution compared to 1.5T systems. But these benefits are limited by the known challenges of a higher field strength including the increased chemical shift artifact, shorter T2 relaxation times for metabolites and an increased need for RF power. An optimized CSI sequence and protocol have been developed to circumvent these challenges. Method and materials: All measurements were performed on 3T MAGNETOM systems, TRIO or ALLEGRA. Data were obtained with the standard Transmit/Receive-Head Coil (USA Instrume…
