We investigated the diagnostic capabilities of I-131, Tl-201, and Tc-99m-MIBI (hexakis-2-methoxyisobutyl- isonitrile) scintigraphy for thyroid cancer metastases after total thyroidectomy over the entire body and for every locus before and after thyroid bed ablation. After total thyroidectomy of thyroid cancer, 36 cases were subjected to I-131 treatment 64 times. They consisted of 17 men and 19 ...

The purpose of the present study was to define myocardial and blood thallium-201 (Tl-201) kinetics after infusion of dipyridamole in normal canine myocardium and in myocardium distal to a coronary artery stenosis. Miniature radiation detector probes were implanted in the left ventricle in 39 open-chest dogs. A balloon constrictor was placed around the proximal left circumflex coronary artery. E...

Information assembled in this chapter will help the reader understand the basis for our preliminary conclusions and will also enable the interested investigator to select samples for further analysis. This information concerns only shipboard operations and analyses described in the site reports in the Leg 201 Proceedings of the Ocean Drilling Program, Initial Reports volume. Methods used by var...

This study assesses the relationship between the distribution of thallium-201 and myocardial blood flow during coronary vasodilation induced by intravenous dipyridamole in canine models of partial and complete coronary artery stenosis. 10 dogs were chronically instrumented with catheters in the left atrium and aorta and with a balloon occluder and electromagnetic flow probe on the proximal left...

OBJECTIVE To determine the safety and prognostic value of dipyridamole thallium-201 scintigraphy performed in patients within three to five days of acute myocardial infarction, including those receiving thrombolytic treatment. DESIGN A prospective study of dipyridamole thallium-201 scintigraphy in patients early after acute myocardial infarction. SETTING University hospital. PATIENTS 200 ...

Sodium nitrite (NaNO(2)) was evaluated in a 55% EBV hemorrhage swine model to mitigate the increased blood pressure due to HBOC-201. Animals were resuscitated by three 10 ml/kg infusions of either HBOC-201 or Hextend with and without NaNO(2). All vital signs, coagulation and blood chemistry were measured for 2 hr. HBOC-201-vasoconstriction was attenuated only after the first 10.8 μmol/kg NaNO(2...

Blood TI-201 activity decayed triexponentially with a final blood X3 = 0.0018±0.0001 min-1, which was almost identical to the final myocardial X2 decay constant. Thu...

The new, belonging to the streptothricin-group antibiotics AN-201 I, II and III were found to be produced by a soil actinomycete identified as Streptomyces nojiriensis C-13. The chemical structures and the physical and spectroscopic properties of these compounds are reported here. On the basis of NMR and fast atom bombardment mass spectrometry (FAB-MS) spectra the antibiotics were identified as...

The standardization of Tl, using the 4π(PC)-NaI(Tl) coincidence system, is presented. The disintegration rate was determined by the extrapolation technique, using two methods: electronic discrimination and external absorbers. A Monte Carlo simulation program, developed in our laboratory, which predicts the behavior of the extrapolation curve, was applied and the results were compared with exper...
