Effect of data-driven motion correction for respiratory movement on lesion detectability in PET-CT: a phantom study.

Journal: EJNMMI physics
Published Date: Jul 11, 2025

Abstract

PURPOSE: While data-driven motion correction (DDMC) techniques have proven to enhance the visibility of lesions affected by motion, their impact on overall detectability remains unclear. This study investigates whether DDMC improves lesion detectability in PET-CT using FDG-18F.
