Integrating respiratory-gated PET-based target volume delineation in liver SBRT planning, a pilot study

BACKGROUND To assess the feasibility and benefit of integrating four-dimensional (4D) Positron Emission Tomography (PET) - computed tomography (CT) for liver stereotactic body radiation therapy (SBRT) planning. METHODS 8 patients with 14 metastases were accrued in the study. They all underwent a non-gated PET and a 4D PET centered on the liver. The same… CONTINUE READING
