Repeatability of the Maximum Standard Uptake Value (SUVmax) in FDG PET

OBJECTIVE SUVmax is often calculated at FDG PET examinations in systematic studies as well as at clinical examinations. Since SUVmax represents a very small portion of a lesion it may be questioned how statistically reliable the figure is. This was studied by assessing the repeatability of SUVmax between two FDG acquisitions acquired immediately upon each other in patients with chest lesions. ...

Repeatability of Standardized Uptake Value in Oncologic 18F-FDG PET

Quantitative analysis can potentially improve the accuracy and consistency of 2-18F-fluoro-2deoxy-D-glucose (18F-FDG) positron emission tomography (PET), particularly for the assessment of tumor response to treatment. Although not without limitations, standardized uptake value (SUV) has emerged as the predominant metric for tumor quantification with 18F-FDG PET. Growing literature suggests that...

TP53 mutations and number of alterations correlate with maximum standardized uptake value (SUVmax) determined by positron emission tomography/computed tomography (PET/CT) [18F] fluorodeoxyglucose (18F-FDG PET)

Background Our study explored the relationship between the molecular changes in cancer and the maximum standardized uptake value (SUVmax) determined by positron emission tomography/computed tomography (PET/CT) with [18F] fluorodeoxyglucose (18F-FDG). Results A higher SUVmax correlated with TP53 alterations, but not with histologic diagnosis or other gene/pathway mutations or copy number alter...

A Novel Method to Evaluate Local Recurrence of Lung SBRT using Follow-up PET Although the method utilizing the maximum standard uptake value (SUVmax) 18F-FDG Positron Emission Tomography (PET) to assess the outcome of lung stereotactic body radiotherapy

Although the method utilizing the maximum standard uptake value (SUVmax) 18F-FDG Positron Emission Tomography (PET) to assess the outcome of lung stereotactic body radiotherapy (SBRT) has been widely accepted in practice, its reliability has frequently been challenged i . The purpose of this study is to explore and test a novel method using a self background-corrected SUVmax (cSUVmax) in detect...

Focal colorectal uptake in (18)FDG-PET/CT: maximum standard uptake value as a trigger in a semi-automated screening setting.

BACKGROUND Focal colorectal uptake in (18)FDG-PET/CT may be associated with a malignancy and can be quantified. This provides the basis for an automatic trigger threshold above which cases are flagged for colonoscopic evaluation and below which for individual assessment. PURPOSE To determine the lowest maximum standard uptake (SUVmax) in colorectal cancer that could be used as a threshold to ...
