Clinical Trial: Using 4DCT Lung Ventilation Imaging to Optimize Radiotherapy for Lung Cancer

U.S., Jan. 1 -- ClinicalTrials.gov registry received information related to the study (NCT07312682) titled 'Using 4DCT Lung Ventilation Imaging to Optimize Radiotherapy for Lung Cancer' on Sept. 09, 2025.

Brief Summary: This retrospective single-center study investigates whether four-dimensional CT (4DCT)-based lung ventilation imaging can guide functional lung avoidance radiotherapy (FLAR) for patients with primary lung cancer.

Ventilation maps generated from planning 4DCT are used to identify well-ventilated lung regions, enabling paired comparison between functional lung avoidance radiotherapy plans and conventional anatomic radiotherapy plans.

The study aims to assess whether incorporating functional lung information into radiotherap...
