Abstract Background Positron emission tomography (PET) traditionally uses coincident annihilation photons emitted from a positron interacting with an electron to localize cancer within the body. The formation of positronium (Ps), a bonded electron-po

Abstract Background Accurate measurement of the arterial input function (AIF) is crucial for parametric PET studies, but the AIF is commonly derived from invasive arterial blood sampling. It is possible to use an image-derived input function (IDIF) o

Abstract Background Until recently, quantitation of the net influx of 2-[18F]fluorodeoxyglucose (FDG) to brain (K i) and the cerebrometabolic rate for glucose (CMRglc) required serial arterial blood sampling in conjunction with dynamic positron emiss

Conclusion: The significantly higher trimethylamine n-oxide levels in patients with coronary artery ectasia without coronary artery disease suggest that the microbiota and its metabolites independently play a role in the pathophysiology or progressio

Blood-based kinetic analysis of PET data relies on an accurate estimate of the arterial plasma input function (PIF). An alternative to invasive measurements from arterial sampling is an image-derived input function (IDIF). However, an IDIF provides t
