results in less uncertainty about the value of the study. For interpreting physicians, economies of time can be achieved by limiting the scan to a single body region, which is consistent with practice guidelines. Decreased patient radiation exposure will also increase acceptance of the technology. Nuclear medicine physicians and radiologists must educate referring physicians about the utilizati...

PET/CT plays an important role in the diagnosis, staging and management of many pediatric malignancies. The techniques for performing PET/CT examinations in children have evolved, with increasing attention focused on reducing patient exposure to ionizing radiation dose whenever possible and minimizing scan duration and sedation times, with a goal toward optimizing the overall patient experience...

Despite considerable excitement about the potential of PET/MR imaging for the detection, staging, and functional characterization of cancer, this new technology is evolving significantly more slowly than PET/CT. This slower evolution is due partly to ongoing technologic challenges (e.g., accurate attenuation correction of PET images) but also to the complex logistics of combining a whole-body P...

This paper examines the merits of using recycled polyethylene terephthalate (PET) in bitumen to improve short and long-term aging bituminous composites used roadway constructions. A concern with PET is its low compatibility leading segregation; here, we functionalized waste cooking oil enhance bitumen. We then studied efficacy delay composites. To do so, particles treated vegetable non-treated ...

This paper evaluates the merits of using waste plastic granules made from functionalized polyethylene terephthalate (PET) to enhance bitumen's bond strength endure extreme environmental conditions such as aging and moisture. The applicability PET a modifier for bitumen has been hindered by PET's low compatibility with bitumen, causing phase separation. In this study, improve flakes were graftin...

Positron emission tomography (PET) is widely used nowadays for tumor staging and therapy response in the clinic. However, average PET radiation exposure has increased due to higher PET utilization. This study aims to review state-of-the-art PET tracer dosage optimization methods after accounting for the effects of human body attenuation and scan protocol parameters on the counting rate. In part...

Homes cannot be made allergen free, but exposure to the major indoor allergens can be reduced. All reduction recommendations are based on the principle of reducing or isolating the source, and certain recommendations can be made on the basis of published evidence. House dust mite avoidance measures include fitting allergen-proof mattress and pillow encasings, washing bedding regularly, and redu...

OBJECTIVE This study was designed to systematically review the emerging role of whole-body positron emission tomography (PET) with 18F-Fluorodeoxyglucose (FDG) in patients with sarcoidosis. DESIGN A comprehensive literature search of published studies through December 2010 in PubMed/MEDLINE and Embase databases regarding whole-body FDG-PET and PET/CT in patients with sarcoidosis was performed...

Cardiovascular imaging has largely focused on identifying structural, functional, and metabolic changes in the heart. The ability to reliably assess disease activity would have major potential clinical advantages, including the identification of early disease, differentiating active from stable conditions, and monitoring disease progression or response to therapy. Positron emission tomography (...

More than a decade ago, multimodality imaging was introduced into clinical routine with the development of the positron emission tomography (PET)/computed tomography (CT) technique. Since then, PET/CT has been widely accepted in clinical imaging and has emerged as one of the main cancer imaging modalities. With the recent development of combined PET/magnetic resonance (MR) systems for clinical ...
