Emerging role of 18F-FDG PET/CT in Castleman disease: a review.

Castleman disease (CD) describes a group of rare hematologic conditions involving lymphadenopathy with characteristic histopathology and a spectrum of clinical abnormalities. CD is divided into localized or unicentric CD (UCD) and multicentric CD (MCD) by imaging. MCD is further divided based on etiological driver into human herpesvirus-8-associated MCD, POEMS-associated MCD, and idiopathic MCD.

Global quantification of pulmonary artery atherosclerosis using F-sodium fluoride PET/CT in at-risk subjects.

The goal of this study was to assess pulmonary artery calcification in healthy controls and subjects with suspicion of stable angina pectoris through the usage of quantitative F-sodium fluoride positron emission tomography/computed tomography (NaF-PET/CT). We hypothesized that these 'at-risk subjects' would demonstrate increase pulmonary artery NaF uptake compared to healthy controls. Retrospectively, 15 healthy controls were compared to 15 at-risk subjects, all of whom underwent full-body NaF-PET/CT scans.
