Association of CT perfusion imaging with plasma levels of TGF-β1 and VEGF in patients with NSCLC.

Objective: To study the association of CT perfusion imaging parameters with plasma level of transforming growth factor-β1 (TGF-β1) and vascular endothelial growth (VEGF) in patients with non small cell lung cancer (NSCLC).

Methods: A total of 67 patients with NSCLC (NSCLC group) and 64 patients with benign lesion (control group) were given with CT perfusion imaging to obtain blood flow, blood volume, mean transit time, time to peal and permeability surface through CT perfusion software. The plasma levels of TGF-β1 and VEGF were tested by ELISA.
