Psychiatry related information on Whole-Body Counting

• We used a sensitive whole body counter which measures potassium-40 (40K) to determine total body potassium and to estimate body cell mass (BCM) in 104 previously untreated patients with upper gastrointestinal malignancies, 233 normal volunteers, and 18 patients with anorexia nervosa [6].

High impact information on Whole-Body Counting

• The measurements included dual x-ray absorptiometry (DXA), prompt gamma-neutron-activation analysis, inelastic neuron scattering, tritiated water dilution, and whole-body counting [7].

• The biologic half-time of thallium was measured by both the Brookhaven whole-body counter and the Donner whole-body scanner, with excellent agreement [11].

Biological context of Whole-Body Counting

• Uncertainties in estimated body burdens of caesium-137 by whole-body counting [12].

Anatomical context of Whole-Body Counting

• Each woman had measurements of total body water taken by a tritiated water dilution technique, total body nitrogen, and total body carbon by neutron-activation, mineral ash by dual x-ray absorptiometry, and body potassium by whole body counting [13].
• Direct and quantitative vitamin B12 absorption studies were performed in 25 patients with disorders in the distal small intestine using whole body counting as the gold standard [2].
• The total amount of thorium determined by the quantitative CT method in the liver, spleen, and lymph nodes was compared with that determined by gamma-ray measurement of the upper abdomen using a whole body counter [14].

Associations of Whole-Body Counting with chemical compounds

• Whole-body counter measurements showed that the retention of activity from the agents exhibiting early plasma protein incorporation was similar to that of L-selenomethionine [15].
• The absorption of iron given per os to ten polycythemic patients was examined by two methods: first by giving radioactive iron (59Fe) and utilizing a whole-body counter, and second by peroral administration of ferrous sulfate [1].
• Ca absorption, determined by whole-body counting of 47Ca, was lower (P less than 0.05) in cheese curd (59%) than in either milk (69%), yogurt (72%), or CaCl2 (72%) [16].
• Manganese retention was monitored in a sensitive whole-body counter during approximately 30 d in six young adult women [17].
• Monitoring of the biodistribution and biokinetics of dysprosium-165 ferric hydroxide with a shadow-shield whole-body counter [18].

Gene context of Whole-Body Counting
