Artifact Detection Using Correlation Analyses Applied to MEGA-PRESS Data Containing Subject Head Movements

Tapper, Sofie ; Tisell, Anders ; Helms, Gunther LU orcid and Lundberg, Peter (2018) p.2655-2655
Abstract
Subject movements and other disturbances might contaminate the Magnetic Resonance Spectroscopy data, and these artifacts can be misinterpreted as actual metabolite signals by the quantification program. Thus, an automatic method could be very helpful for finding artifacts and eliminating them. In this work, an approach of using correlation analyses was tested in order to evaluate if motion contaminated data could be identified. A total of 296/320 spectra were correctly categorized according to the movement-paradigm. This procedure could be suitable for identifying data that are affected by subject motion or other artifacts that would reduce the quality of the result.
