Background: Cardiovascular implantable electronic devices (CIED) infections are life-threatening complications. The diagnosis can be difficult to establish. Our purpose is to evaluate the diagnostic value of (18)F-FDG PET.

FDG uptake in the immediate vicinity of the odontoid process, with a crownlike calcification, was identified on the CT scan on the posterior side of the dens, thus confirming the diagnosis of crowned dens syndrome. Because this rare syndrome is frequently misdiagnosed, nuclear physicians should be aware of the signs and symptoms of this condition, which may call for the use of PET/CT imagery.

Methods: Forty consecutive patients with proven pulmonary hypertension underwent V/Q scintigraphy and DECT perfusion and angiography. Each imaging technique was assessed for the location of segmental defects.
Background: A pacemaker recipient may be hospitalized recurrently with an infection of unknown origin despite detailed investigations.
Objective: The purpose of this study was to investigate whether (18)F-fluorodeoxyglucose positron emission tomography/computerized tomography (FDG-PET/CT) scanning has a role in identifying pacing material infection in these difficult cases.
Methods: Ten patients who presented with fever of unknown origin despite detailed investigations including transesophageal echocardiography underwent FDG-PET/CT scanning.
