A 66-year-old male patient with fever and coughing, clinically suspected pneumonia. The plain chest X-ray (a) demonstrates a dense infiltrate in the left lower lung lobe which is confirmed on non-contrast-enhanced low dose CT (b; arrows). The patient volunteered to undergo MRI on the same day. Multi-breath-hold coronal T2-weighted fast spin echo (c) and single breath-hold T1-weighted 3D GRE imaging (d) as well as free breathing coronal steady state SSFP (e) and multi-breath-hold fat-saturated T2-weighted fast spin echo series (f) clearly demonstrate the infiltrates with particularly high signal on T2-weighted images
