Investigating respiratory motion artefacts and ROPE in magnetic resonance spectroscopy

Theodoros N. Arvanitis, Des Watson

This research paper presents the problem of respiratory motion and the associated artefacts in Magnetic Resonance Spectroscopy. The nature and the appearance of respiratory motion artefacts, already extensively investigated in conventional 2D Fourier transform Magnetic Resonance Imaging, is studied in combination with the possibility of using the ROPE (Respiratory Ordered Phase Encoding) method to reduce such artefacts. In particular the study is focused on spectroscopic CSI and processing of the data is done by using the autocorrelation function.
