Gallium-67 citrate is currently considered as the tracer of first choice in the diagnostic workup of fever of unknown origin (FUO). Fluorine-18 2'-deoxy-2-fluoro-D-glucose (FDG) has been shown to accumulate in malignant tumours but also in inflammatory processes. The aim of this study was to prospectively evaluate FDG imaging with a double-head coincidence(More)
This study investigated the value of fluorine-18 2'-deoxy-2-fluoro-D-glucose (FDG) imaging with a double-headed gamma camera operated in coincidence (hybrid PET) detection mode in patients with suspected spondylitis. Comparison was made with conventional nuclear medicine imaging modalities and magnetic resonance imaging (MRI). Sixteen patients with(More)
Takayasu aortitis (TA) is a chronic inflammatory and fibrotic vasculitis of large- and medium-sized arteries. Early stages of the disease show a panarteritis and inflammatory wall thickening of the aorta and its branches, whereas advanced (fibrotic) stages comprise stenosis, aneurismatic transformation and occlusion. Magnetic resonance imaging visualises(More)
BACKGROUND Recently allergic reactions to legumes mediated by Bet v 1-homologous food allergens were described for soy and peanut. In this study we assessed allergic reactions to another legume, to mungbean seedlings, and identified its Bet v 1-homologous allergen Vig r 1. METHODS Ten patients were selected who had a history of allergic reactions to(More)
Ziel unserer 3jährigen, prospektiven Studie war die Wirksamkeit einer Radiosynoviorthese mit Rhenium-186 oder Erbium-169 , und zwar in der Therapie der rheumatischen Artikulosynovitis, anhand klinischer und radiologischer Parameter vergleichend zu beurteilen. Als Kontrolle diente die Injektionstherapie mit Triamcinolonhexacetonid. Als Studienkriterien(More)
At the molecular level, the uptake of radioiodine and pertechnetate is proportional to the expression of the thyroidal sodium/iodine symporter (NIS). Qualitative and quantitative scintigraphic evaluation of the thyroid is performed with a gamma camera fitted with an on-line computer system and enables determination of the iodine uptake or the technetium(More)
CD4 expressing T-lymphocytes are involved in the pathogenesis of rheumatoid arthritis, so the possibility of using radiolabelled CD4-specific antibodies to localise diseased joints was studied. Prospectively six patients with rheumatoid arthritis were investigated. Five of them received 200–300 μg of a 555 MBq technetium 99m CD4-specific antibody (MAX.16H5)(More)
There is a weak association between Alzheimer's disease (AD) and the histocompatibility antigen HLA-A2, suggesting that A2 has either a minor role in AD or a major role in a subtype of it. To test these alternatives, we studied 54 consecutively ascertained AD patients diagnosed by NINCDS-ADRDA criteria. Patients had a higher frequency of A2 than control(More)
Since its introduction in 1976 as an imaging procedure, the use of labelled leucocyte scintigraphy has continued to increase. Nowadays it is a routine procedure in most nuclear medicine departments for the investigation of different inflammatory pathologies involving leucocytic infiltration. These include bone and soft tissue infections, inflammatory bowel(More)
