Abstract null null Acute intoxication with tetramethylenedisulfotetramine (TETS) can trigger status epilepticus (SE) in humans. Survivors often exhibit long-term neurological effects, including electrographic abnormalities and cognitive deficits, but the pathogenic mechanisms linking the acute toxic effects of TETS to chronic outcomes are not known. Here, we use advanced in vivo imaging techniques to longitudinally monitor the neuropathological consequences of TETS-induced SE in two different mo...

CONTEXT Studies in rodents and humans suggest that high fructose corn syrup (HFCS)-sweetened diets promote greater metabolic dysfunction than sucrose-sweetened diets. OBJECTIVE To compare the effects of consuming sucrose-sweetened beverage (-SB), HFCS-SB, or a control beverage sweetened with aspartame on metabolic outcomes in humans. DESIGN A parallel, double-blinded, NIH-funded study. SETTING Experimental procedures were conducted during 3.5 days of inpatient residence with controlled feeding a...

ABSTRACT This study systematically reviewed the published literature on the objective characterization of myofascial pain syndrome and myofascial trigger points using imaging methods. PubMed, Embase, Ovid and the Cochrane Library databases were utilized, while citation searching was conducted in Scopus. Citations were restricted to those published in English and in peer-reviewed journals between 2000-2021. Out of 1,762 abstracts screened, 69 articles underwent full-text review and 33 were includ...

Nuclear medical imaging devices, such as those enabling photon emission imaging (gamma camera, single photon emission computed tomography (SPECT), or positron emission imaging (PET)), that are typically used in today's clinics are optimized for assessing large portions of the human body, and are classified as whole-body imaging systems. These systems have known limitations for organ imaging, therefore application-specific devices have been designed, constructed and evaluated. These devices, give...

1697 Purpose: Total-body PET/CT scanners offer the unique ability to evaluate the systemic inflammatory burden of autoimmune inflammatory arthritic (AIA) conditions using ultra-low dose protocols. However, AIA patients are unable to tolerate long scan times. We prospectively evaluated the influence of shortening the scan time on image quality in participants with AIA and non-AIA controls using a total-body PET/CT scanner. Methods: Participants with an established AIA condition (Rheumatoid Arthri...

Imaging of musculoskeletal disorders, including arthritis, infection, osteoporosis, sarcopenia, and malignancies, is often limited when using conventional modalities such as radiography, computed tomography (CT), and MR imaging. As a result of recent advances in Positron Emission Tomography (PET) instrumentation, total-body PET/CT offers a longer axial field-of-view, higher geometric sensitivity, and higher spatial resolution compared with standard PET systems. This article discusses the potenti...

Objectives To prospectively demonstrate the feasibility of performing dual-phase SPECT/CT for the assessment of the small joints of the hands of rheumatoid arthritis (RA) patients, and to evaluate the reliability of the quantitative and qualitative measures derived from the resulting images. Methods A SPECT/CT imaging protocol was developed in this pilot study to scan both hands simultaneously in RA patients, in two phases of 99mTc-MDP radiotracer uptake; namely the soft-tissue blood pool phase ...

Rodent studies demonstrate that compared with diets sweetened with sucrose, high fructose corn syrup (HFCS) produces greater metabolic dysfunction. However, the effects of sustained consumption of HFCS and sucrose have not been adequately compared in humans. The objective of this study was to compare HFCS-, sucrose-, or aspartame- sweetened beverage (-SB) consumption on hepatic lipid content and insulin sensitivity in young adults. In a parallel, double-blinded study, adult men and women (18-40 ...

331 Purpose: Rheumatoid arthritis (RA) and psoriatic arthritis (PsA) are systemic autoimmune conditions that typically involve multiple joints and organs. Conventional 18F-FDG PET/CT scans have been infrequently used in RA and PsA and are commonly hampered by limitations, such as spatial resolution and sensitivity characteristics of conventional scanners, which limit the detection of synovitis and small lesions in the hand and feet joint. The high-sensitivity, high-resolution uEXPLORER, a 194-cm...
