Discrepancies in Gross Tumor Volume and Motion between 4D-CT and Magnetic Resonance Imaging for Stereotactic Body Radiotherapy: A Phantom and Patient Study

2026-04-20

Abstract excerpt

<title>Abstract</title> <p>Background Precise delineation of gross tumor volume (GTV) and accurate assessment of respiratory motion are critical for stereotactic body radiotherapy (SBRT) of lung and liver tumors. This study aimed to systematically compare CT- and MRI-based tumor volume delineation and motion assessment using a dynamic phantom and patient data, with phantom-based 4D-MRI and real-time cine-MRI inc...
