Feasibility of Global Assessment of Bone Metastases in Prostate Cancer with F-Sodium Fluoride-PET/Computed Tomography.

18F-sodium fluoride (NaF) PET/computed tomography (CT) allows detection of bone metastases in patients with prostate cancer (PCa). The aim of this study was to test the feasibility of assessing global metastatic bone disease in patients with PCa by using a threshold-based PET segmentation technique. This retrospective analysis was performed in 32 patients with PCa with known bone metastases who underwent NaF-PET/CT imaging.

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.

F-FDG-PET/CT in the assessment of atherosclerosis in lung cancer.

The aim of this study was to assess the risk of atherosclerosis in patients with lung cancer compared to patients with extrapulmonary malignancies using F-fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT). We hypothesized that patients with lung cancer would demonstrate increased FDG uptake in the thoracic aorta compared to patients with extrapulmonary cancers. Thirty-four lung cancer patients (21 male, 13 female, 64.

Global brain glucose uptake on 18F-FDG-PET/CT is influenced by chronic cardiovascular risk.

Purpose: The goal of this study was to assess global cerebral glucose uptake in subjects with known cardiovascular risk factors by employing a quantitative 18F-fluorodeoxyglucose-PET/computed tomography (FDG-PET/CT) technique. We hypothesized that at-risk subjects would demonstrate decreased global brain glucose uptake compared to healthy controls.

Methods: We compared 35 healthy male controls and 14 male subjects at increased risk for cardiovascular disease (CVD) as assessed by the systematic coronary risk evaluation (SCORE) tool.

Applications of Hybrid PET/Magnetic Resonance Imaging in Central Nervous System Disorders.

PET with 18F-fluorodeoxyglucose (FDG) is used to assess a wide array of inflammatory and neoplastic disorders. FDG-PET has shown particular utility in the evaluation of disorders of the central nervous system (CNS). Although fused PET/computed tomography (CT) is frequently used across the globe for these diseases, recent evidence has pointed to PET/magnetic resonance (MR) imaging as a more sensitive and specific molecular imaging modality.

Diagnosis and Monitoring of Osteoporosis with Total-Body F-Sodium Fluoride-PET/CT.

In recent years, F-Sodium Fluoride (NaF)-PET/CT has seen its role in the detection and management of osteoporosis increase. This article reviews the extent of this application in the literature, its efficacy compared with other comparable imaging tools, and how total-body PET/CT combined with global disease assessment can revolutionize measurement of total osteoporotic disease activity. NaF-PET/CT eventually can be the modality of choice for metabolic bone disorders, especially with these advances in technology and computation.

Role of F-NaF-PET in assessing aortic valve calcification with age.

Aortic valve calcification is a slow and progressive pathological process that can manifest in various degrees from mild thickening of the valve known as aortic sclerosis to severe calcification that hinders the leaflet motion, known as aortic stenosis. The evolving concept of aortic calcification is thought to result from infiltration of macrophages and T-lymphocytes. Moreover, the incidence of aortic valve calcification increases with age, in particular over the age of 50.
