Translation and establishment of complex pulmonary magnetic resonance (MR) imaging techniques in the clinics requires a reliable, fully automated and fast calculation. In this work we present a semantic convolutional neural network (CNN) model for lung parenchyma and vessel segmentation in combination with parallelized computation on a high-performance computer to design an end-to-end pipeline for phase-resolved functional lung (PREFUL) MRI. The CNN was trained (n=1118) and validated (n=1064) with manually segmented images by a trained radiologist. Automatic segmentation of lung parenchyma was achieved for all tested images.
