Thallium-201 scanning to decide CCU admission in patients with non-diagnostic electrocardiograms.

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 infarction within 2 months, and in 11 coronary heart disease was proven by angiography or strongly suggested by stress tests (ECG and thallium-201 scan).

111Indium-labelled leucocyte scintigraphy in the diagnosis of inflammatory disease--first results.

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, whereas 9 scintigrams had to be considered as false negative.

Comparison of indium-111 oxinate labelled autologous granulocytes with indium-111 oxinate and indium-111 chloride as abscess scanning agents. An experimental study in an animal model.

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.
