Analysis of dynamic lung oxygen-enhanced MRI (OE-MRI) is challenging due to the presence of substantial artefacts and poor SNR. Understanding and minimising sources of error is critical for reliable use of the method. We have created a pipeline using independent component analysis (ICA) for the automatic extraction of functional lung information from dynamic lung OE-MRI, for which confounding factors are reduced. The pipeline demonstrated good repeatability when utilised for the analysis of a scan-rescan dynamic lung OE-MRI study at 3.0 T; the algorithmic uncertainty of ICA on the analysis pipeline was found to be minimal.
