A number of in vitro cell and tissue culture methodologies have been employed to study the
potential exploitation of transport mechanisms for the delivery of peptidergic molecules …

A technique is described for transaxial imaging of the thorax during pulmonary perfusion
study. The contours of the air-containing lungs were obtained by gamma-ray transmission …

Objective: Cardiac PET imaging offers the potential capability for the noninvasive
measurement of arterial input function. This capability is somewhat limited, however …

To determine the spatial distributions of pulmonary perfusion, shunt, and ventilation, we
developed a compartmental model of regional 13N-labeled molecular nitrogen (13NN) …

Soluble radioaerosols such as technetium-99m diethylene triamine pentacetate (DTPA)
permit simple quantitative studies of alveolar-capillary permeability to be performed, since …

Methods Uptake of tritiated thymidine, L-leucine, L-methionine and FDG into two human
tumor cell lines (HTB 63 melanoma and HTB 77 IP3 ovarian carcinoma) was determined …

Images were reconstructed at specific time intervals until the average measured
radioactivityin regions placed within the head region of PET phantom images decayed in a …

Translocator protein (TSPO)(18 kDa), formerly called the peripheral benzodiazepine
receptor, is upregulated on activated microglia and macrophages and is, thus, a biomarker …

Measurement of pulmonary clearance of an inhaled aerosol of technetium-99m labelled
diethylenetriaminepenta-acetate (DTPA) by external detection methods has been used …

Pulmonary uptake of 18F-FDG assessed with PET has been used to quantify the metabolic
activity of inflammatory cells in the lung. This assessment involves modeling of tracer …
