An 82-year-old woman was admitted to our hospital or evaluation of a mass in the right orbit of 4 months uration. She had no ocular symptoms, fever, sweatng, or weight loss. On physical examination, a 4-cm ass was palpated in the soft tissue of the right orbit. o lymphadenopathy or organomegaly were detected. allium scan showed increased tracer uptake in the ight orbit and in both parahilar reg...

There is some disagreement in the literature about the tumour affinity and tumour specificity of gallium-67 (6VGa). The present investigation showed good uptake of 67Ga in most cases of bronchial carcinoma, but some uptake of 67Ga was also found in 30% of those with non-malignant lung lesions. There was no relationship between the uptake of 17Ga and the histo-logical type of bronchial carcinoma...

A patient with atypical presentation of polymyalgia rheumatica is presented. Her major symptoms were mild weakness, pain on passive movement of the shoulder and hip girdles, with mild tenderness but no joint stiffness. Muscle enzymes were within the normal range. The diagnostic work-up included gallium-67 scintigraphy, which showed intense uptake in both shoulders, with remarkable improvement f...

OBJECTIVE To evaluate gallium-67 (67Ga) uptake and the value of 67Ga scintigraphy for diagnosis of macrophagic myofasciitis (MMF), a recently identified inflammatory myopathy. METHODS Twelve consecutive patients with MMF confirmed by muscle biopsy, 10 with polymyositis, 10 with sarcoidosis, 8 with fibromyalgia, and 10 with lymphoma without muscle symptoms (serving as normal controls for muscl...

BACKGROUND Gallium-67 scintigraphy has been suggested as a noninvasive method to diagnose acute interstitial nephritis (AIN). However, its diagnostic performance and usefulness remain controversial. METHODS We retrospectively reviewed the charts of 76 patients who underwent gallium-67 scintigraphy for a suspicion of AIN. Patients were classified based on kidney biopsy and/or clinical probabil...

Introduction: This study was launched to evaluate the sensitivity and specificity of 99mTc-Ciprofloxacin to distinguish infection foci induced by staphylococcus aureus and inflammation lesions induced by carrageenan in the rat foot in comparison with 67Ga-Citrate scintigraphy. Methods: The labeling and quality control of 99mTc-Ciprofloxacin kits have been perfo...

BACKGROUND The diagnosis of spondylodiscitis can be difficult, because the patients history, subjective symptoms and physical findings are often inconclusive, particularly in the early stages. AIM To perform an overview on the role of nuclear medicine procedures with single photon emission tomography (SPET) and positron emission tomography (PET) tracers in the diagnosis of spondylodiscitis. ...
