A 29-year-old female with cystic fibrosis. The axial T2-weighted (BLADE; a) and the volumetric contrast-enhanced 3D-GRE (VIBE; b) breath-hold acquisitions show severe bronchiectasis, bronchial wall thickening, mucus plugging, pleural effusion as well as a destructed middle lobe. The perfusion subtraction image (c) shows a severely impaired perfusion pattern with loss of perfusion in several areas. The maximum enhancement (MAX) and time to peak anhancement (TTP maps) allow for a further characterisation of the perfusion impairment. Most areas with impaired perfusion show a reduced (MAX map) and delaid (TTP map) perfusion. Notice the area in the left upper lobe with reduced but not delayed perfusion (arrowhead)
