This article reviews the contribution made by nuclear imaging to the assessment, diagnosis
and monitoring of patients with respiratory disease. It focuses on several specific areas …

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 measured extravascular density (EVD) and the pulmonary transcapillary escape rate
(PTCER) for 68Ga-transferrin using positron emission tomography in 14 normal volunteers …

Much of our present understanding of regional lung function derives from experiments using
radio active tracers. Today studies of regional pulmonary blood flow and regional ventilation …

Emission tomography provides three-dimensional, quantitative images of the distribution of
radiotracers used to mark physiological, metabolic, or pathological processes. Quantitative …

Onset of lung edema is usually associated with increase in the pulmonary transvascular flux
of water and proteins. Clinical measurement of these parameters may aid in early diagnosis …

Approximately 170,000 people arediagnosed with lung cancer in the United States each
year. Manyof these patients receive external beam radiation for treatment. Fluorine-18 2 …

MATERIALS AND METHODS Patient studies. In order to estimate ranges of clinically
observed count rates and clearance times, we reviewed ventilation-perfusion scintigrams of …

Purpose It has recently been recognized that PET/CT may play a role in diffuse parenchymal
lung disease. However, interpretation can be confounded due to the variability in lung …

We have developed a new quantitative single-photon-emission computed tomography
(SPECT) method that uses 113mIn-labeled albumin macroaggregates and Technegas …
