OBJECTIVE Alzheimer's disease (AD) and frontotemporal dementia (FTD) are among the most frequent neurodegenerative cognitive disorders, but their differential diagnosis is difficult. The aim of this study was to evaluate an automatic method returning the probability that a patient suffers from AD or FTD from the analysis of brain perfusion single photon(More)
UNLABELLED (123)I-FP-CIT ((123)I-N-omega-fluoropropyl-2beta-carbomethoxy-3beta-(4-iodophenyl)nortropane) is a SPECT dopamine transporter (DAT) tracer that probes dopaminergic cell loss in Parkinson's disease (PD). Quantification of (123)I-FP-CIT images is performed at equilibrium using a ratio (BR) of specific (striatal) to nonspecific (occipital) uptake(More)
UNLABELLED Imaging techniques have demonstrated in various cardiomyopathies that an altered uptake of radiolabeled norepinephrine (NE) analogs may coexist with beta-adrenergic receptor downregulation, but the relationships between these 2 alterations and their mechanisms remain unclear. The aim of this study was to evaluate the hypothesis of a chronic(More)
OBJECTIVE (18)F-fluorodeoxyglucose-positron emission tomography (FDG-PET) scanning has been proposed as a new way of assessing disease activity in Takayasu arteritis (TA), but previous studies have used the nonvalidated National Institutes of Health (NIH) global activity criteria, and thus might be biased. This study was undertaken to determine the value of(More)
OBJECTIVE Erdheim-Chester disease (ECD) is a rare form of non-Langerhans' cell histiocytosis. The aim of this study was to assess the value of whole-body scanning with (18)F-fluorodeoxyglucose-positron emission tomography (FDG-PET) in a large cohort of ECD patients from a single center. METHODS We retrospectively reviewed all PET scans performed on 31(More)
OBJECTIVES Nicotine therapy might improve the course of Parkinson's disease. This observational study evaluated the performance of dopamine transporter imaging in follow-up patients under nicotine therapy. METHODS Six Hoehn and Yahr stage III patients underwent 123I-FP-CIT imaging prior to, 3 months, and 1 year after the onset of nicotine therapy.(More)
PURPOSE The purpose of this study was to investigate the feasibility and utility of dual-isotope SPECT for differential diagnosis of idiopathic Parkinson's disease (IPD) and multiple system atrophy (MSA). METHODS Simultaneous (99m)Tc-ECD/123I-FP-CIT studies were performed in nine normal controls, five IPD patients, and five MSA patients. Projections were(More)
STUDY DESIGN A case of atypical osseous tuberculosis (TB) mimicking multiple secondary metastases on radiologic and nuclear imaging is presented. OBJECTIVES To emphasize the contribution of nuclear bone scanning for the assessment of osseous tuberculosis in typical and atypical presentations. SUMMARY AND BACKGROUND DATA Skeletal locations of TB mostly(More)
Impaired thyroid function-hypothyroidism, is associated with changes in the spectrum of serum lipids. Thyroid hormones increase the number and activity of LDL receptors in the liver and peripheral tissues and have also a direct impact on the triacylglycerol synthesis in the liver. If their amount in the organism is inadequate, the metabolic turnover of(More)
The effectiveness and tolerance of the new sulphonyl urea antidiabetic gliquidone (commercial name Glurenorm) was tested by three-month administration of this preparation in a group of 39 type 2 diabetics. Gliquidone proved a medium-strength beta-cytotropic antidiabetic preparation. As to side-effects, the authors noted only dyspepsia in one patient (2.5%).(More)
