Regional lung hematocrit ratio (R) was measured in five normal subjects and five patients (2
with pneumonia, 2 with nephrotic syndrome with anemia, and 1 with pancreatitis) using …

We have measured regional pulmonary blood flow (PBF) in normal dogs with positron
emission tomography (PET) and 15O-labeled water (H2 (15) O). The method is …

We have measured with positron emission tomography (PET) the regional distribution of
extravascular lung water (EVLW) and hematocrit (HctL) in normal supine dogs. H2 (15) O …

A technique has been developed to measure regional values of vascular and extravascular
lung density using positron emission and transmission tomography. Quantitative values of …

Regional pulmonary blood flow (PBF), regional pulmonary extravascular water (PEW), and
regional pulmonary blood volume (PBV) were measured quantitatively with positron …

Cr51-labeled red cells and Evans blue dye were used to measure cardiac output, circulating
pulmonary and total red cell volumes, plasma volumes and resultant pulmonary and body …

The total body hematocrit has been reported to be 85–90% of packed cell volume (PCV) in
several species. We have found similar values in rabbits. An “extra” plasma volume must …

Regional lung density (DL) and regional fractional pulmonary blood volume (VB) were
measured quantitatively during tidal breathing in 30 healthy supine subjects (15 smokers …

Regional pulmonary blood flow (rPBF) can be measured with an intravenous infusion of 15O-
labeled water and positron emission tomography (PET). The current method depends on …

The adaptation to positron emission tomography of the steady-state technique for the
measurement of alveolar ventilation, based on the shortlived radionuclide neon-19 (T,= 17.4 …
