Spectroscopy in Neuroradiology: A Practical Guide

Motivation: Magnetic resonance spectroscopy (MRS) is a valuable tool in neuroradiology, enabling the analysis of the chemical composition of brain tissues. This paper will present the fundamentals of MRS and the technical challenges encountered during acquisition. Goal(s): The objective is to provide technicians with the keys to optimize acquisition parameters and obtain high-quality spectra. Approach: The main topics addressed include sequence selection, water suppression, parameter optimization, and artifact management. Results: MRS is a valuable tool for studying brain lesions. The role of the technician is crucial in optimizing its use. This work aims to facilitate its adoption by sharing best practices. Impact: This study aims to democratize the use of MRS in neuroradiology by providing technicians with a practical guide to improve spectrum quality, thereby facilitating result interpretation and enhancing patient care.
