Radiochemistry for positron emission tomography

Nature Communications, 2023
AbstractPositron emission tomography (PET) constitutes a functional imaging technique that is harnessed to probe biological processes in vivo. PET imaging has been used to diagnose and monitor the progression of diseases, as well as to facilitate drug development efforts at both preclinical and clinical stages.

NMF on Positron Emission Tomography [PDF]

2007 IEEE International Conference on Acoustics, Speech and Signal Processing - ICASSP '07, 2007
In positron emission tomography, kinetic modelling of brain tracer uptake, metabolism or binding requires knowledge of the cerebral input function. Traditionally, this is achieved with arterial blood sampling in the arm or as shown in (Liptrot, M, et al., 2004) by non-invasive K-means clustering.
