Correcting for Frequency Drift in Clinical Brain MR Spectroscopy
Abstract
Averaging multiple repetitions to improve signal‐to‐noise ratio is common practice in magnetic resonance spectroscopy (MRS). However, temporal variations in scanner B0 due to motion or gradient heating may cause spectra to become misaligned, broadening and distorting peaks and impacting on processing and quantification. We present a comparison using in vivo data of different methods for correcting these errors.
