Comparative Assessment of Methods for Estimating Tumor Volume and Standardized Uptake Value in ¹⁸F-FDG PET

Abstract

The method used to estimate tumor volume and SUV greatly affects the reliability of the estimates. The T(bgd) and Fit methods yielded low errors in volume estimates in a broad range of situations. The PVE-corrected SUV based on T(bgd) and Fit were more accurate and reproducible than SUV(max).
