Summary

Patients with early-stage lung cancer undergo surgery unless preoperative evaluation reveals poor lung function, which is predictive of poor outcomes. Imaging—like MRI or CT scans—isn't the standard of care for conventional evaluation due to issues like cost, the need for contrast and inaccuracy. Thomas Jefferson University researchers used another imaging modality—four-dimensional computed tomography ( 4 DCT)-ventilation—to preoperatively assess lung function in patients with early-stage lung cancer. 4 DCT-ventilation is often used in radiation oncology, but this is the first time it was used in a surgical trial.
