Accurate quantification in PET and SPECT requires correction for a number of physical
factors, such as photon attenuation, Compton scattering and random coincidences (in PET) …

Attenuation correction in single-photon (SPET) and positron emission (PET) tomography is
now accepted as a vital component for the production of artefact-free, quantitative data. The …

Neoplastic tissue in general shows a high rate of glucose consumption under both
anaerobic and aerobic conditions. Using positron emission tomography (PET) we measured …

The discovery of X-rays in 1895 heralded a new era in the practice of medicine—
visualization into the body without painful and often life-threatening surgery. However, not …

Regional pulmonary glucose metabolism (MR glu; μmol h− 1 g− 1), extravascular lung
density (D EV; g cm− 3) and vascular volume (VB; ml cm− 3) were measured in a single …

Background Pulmonary congestion is a common presentation of acute decompensated
heart failure (ADHF). The ability to quantify increased pulmonary parenchymal water content …

Effective anticancer therapy induces tumor cell death through apoptosis. Noninvasive
monitoring of apoptosis during therapy may provide predictive outcome information and help …

BACKGROUND We have developed a new measure of myocardial viability, the water-
perfusable tissue index (PTI), which is calculated from transmission, C15O, and H2 (15) O …

Quantification of pulmonary edema and congestion is important to guide diagnosis and risk
stratification, and to objectively evaluate new therapies in heart failure. Herein, we review …

[18F] 16α-fluoroestradiol (FES) is a PET imaging agent useful for the study of estrogen
receptors in breast cancer. We estimated the radiation dosimetry for this tracer using data …
