F-FDG PET/CT may be helpful with localization of painful abnormalities in the inflamed regions of the joints, which could potentially be used to direct individualized treatment in moderate and severe OA. Furthermore, SUV measurement on F-FDG PET/CT could serve as an inflammation activity index in the knees that may be predictive of outcomes and progression rate of OA.
Chronic thromboembolic pulmonary hypertension (CTEPH) is a potentially lethal outcome of pulmonary embolism. Balloon pulmonary angioplasty (BPA) is aimed at improving pulmonary perfusion and pulmonary hemodynamics and has gained a lot of interest recently in patients either unsuitable for or refractory to surgical pulmonary endarterectomy. This article outlines the clinical features and diagnostic criteria, imaging evaluation, current medical and surgical treatment options for CTEPH. BPA is discussed in detail, focusing on the rationale, patient selection, technical details, post-procedural care and outcomes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
