To determine the value of thallium-201 scintigraphy as a decisive factor in admission policy for patients with acute chest pain and nondiagnostic electrocardiograms, we undertook a prospective study in 149 such patients. The interval between pain and scan never exceeded 12 hr. Of 57 patients in whom a defect was seen, 34 had an acute infarction, 7 developed… (More)
An abnormal uptake pattern of 201Tl thallous chloride observed during myocardial scintigraphy of a patient with known thoracic tumour localization suggested the possibility that thallous chloride may also accumulate in tumours. This was confirmed by observing 201thallous chloride accumulation in rhabdomyosarcoma implants in rats. Thallium 201 accumulation… (More)
A case of a benign hepatic-cell adenoma studies with dynamic radionuclide angiography and static imaging with different tracers is presented.
In 61 patients, 66 scans were performed with 111In-labelled autologous leucocytes to evaluate this method in the diagnosis of inflammatory disease. All scintigraphic results were compared with clinical, operative or postmortem findings. In the first 20 examinations in 19 patients, 2 scintigrams were true positive, 9 true negative one of false positive,… (More)
Bacterial abscesses were evoked in goats. Imaging of these abscesses was obtained by means of labelling autologous granulocytes with 111In oxinate, reinjection of the cells into the animal, and scintigraphy by gamma camera one day later. Comparable imaging results, however, were obtained after intravenous injection of 111In oxinate or of 111In chloride. The… (More)
