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) …

PET has the invaluable advantage of being intrinsically quantitative, enabling accurate
measurements of tracer concentrations in vivo. In PET tumor imaging, indices characterizing …

Semiquantitative standard uptake values (SUVs) are used for tumor diagnosis and response
monitoring. However, the accuracy of the SUV and the accuracy of relative change during …

Despite the increasing use of 18F-FDG PET as a biomarker for predicting therapeutic
response, there are no widely accepted standardized protocols for using 18F-FDG PET as a …

Characterization of a pulmonary lesion is a well-established indication for metabolic imaging
with 18F-FDG. There is extensive literature on the use of PET and CT in the characterization …

In this review, the fundamental principles of fluorodeoxyglucose (FDG) positron emission
tomography (PET) and FDG PET/computed tomography (CT) imaging have been described …

We previously reported that respiratory motion is a major source of error in quantitation of
lesion activity using combined PET/CT units. CT acquisition of the lesion occurs in seconds …

Benign and malignant pulmonary lesions usually are differentiated by 18F-FDG PET with a
semiquantitative 18F-FDG standardized uptake value (SUV) of 2.5. However, the frequency …

The role of the fluorodeoxyglucose (FDG) technique positron emission tomography (PET) is
well established in the management of patients with lung cancer. Increasingly, it is becoming …

In the early days of PET, the partial volume effect (PVE) was identified as a serious factor
affecting image quality and limiting the accuracy of quantitative analysis. Because of the …
