¹⁸F-FDG PET/CT of cardiovascular device infection. (A) Prosthetic valve endocarditis: CT, PET, and PET/CT fusion images in representative transaxial and coronal views, along with whole-body maximum-intensity projection (MIP). Intense uptake is present at aortic valve prosthesis, implanted 2 y previously. MIP shows additional focal ¹⁸F-FDG–avid embolus in right lower leg (arrow). (B) Left-ventricular assist device infection. Intense uptake is seen around device and outflow tract in left chest wall (left) and along driveline (right) in patient with diffuse reddening and swelling of left chest wall and purulent drainage at entry side of driveline. MIP shows additional uptake in reactive mediastinal lymph nodes.
