Standardized Uptake Values
Standardized Uptake Values Richard L. Wahl Positron emission tomography (PET) and PET/CT (computed tomography) are inherently quantitative techniques. Properly performed attenuation-corrected images from well-calibrated scanners accurately reflect radioactivity concentrations in…
PET Physics and PET Instrumentation
PET Physics and PET Instrumentation Timothy G. Turkington Positron emission tomography (PET) quantitatively measures the biodistribution of positron emitting radiotracers in vivo. Positrons emitted from positron-emitting radioisotopes radiotracers, which travel…
