MRI offers many advantages for chest imaging such as the absence of irradiation and the opportunity to obtain images with various contrasts in soft tissues. Developing MRI lung imaging would provide solutions to a real public health problem related to lung disease. Besides, PET is relevant for the study of metabolic changes caused by parenchymatous affections. Hence PET-MRI is a promising route for the characterization of lung diseases. One of the immediate issues lung imaging raises is motion. Physiological motion needs to be taken into account during the imaging process to avoid blurring or ghosting artifacts in both imaging modalities.
