This study examines (he accuracy of radionuclide methods currently used for assessing
regional pulmonary function in patients. Dogs were heparinized, exsanguinated, and their …

Nonuniform distributions of lung perfusion scintiscans obtained by SPECT were quantified to
supplement qualitative lung scintiscans. A total of 126 lung perfusion scintigraphy …

Purpose: Three-dimensional single photon emission computed tomography lung perfusion
scans (SPECT) provide a unique quantitative 3-dimensional map of the distribution of …

Lung scintigraphy is the primary tool for diagnostics of pulmonary embolism. A perfusion
study is often complemented by a ventilation study. Intermediate probability scans are …

We describe a technique to obtain non‐invasively regional pulmonary ventilation–perfusion
ratios (V˙ A/Q˙) using single photon emission computed tomography (SPECT) and …

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 …

From the first measurements of the distribution of pulmonary blood flow using radioactive
tracers by West and colleagues (J Clin Invest 40: 1–12, 1961) allowing gravitational …

Single photon emission computed tomography (SPECT) has replaced planar imaging in
many areas of nuclear medicine. Given its superior contrast resolution and improved …
