Clinical validation of a unified data-driven respiratory motion correction technique in 18F-FDG PET/CT imaging of upper abdominal lesions: a real-world study.

Key Points

• To evaluate the effectiveness of a unified data-driven respiratory motion correction (uRMC) algorithm in PET/CT imaging for upper abdominal lesions.
• Compared uRMC algorithm with conventional non-motion correction (NMC) reconstruction.
• Assessed image quality, PET-CT alignment, and lesion delineation.
• Conducted analysis in a real-world clinical setting.
• Significant improvement in overall image quality with uRMC.
• Enhanced alignment between PET and CT images.
• Improved detection of low-uptake and small-volume lesions, aiding clinical diagnoses.
