First-pass CT perfusion of pulmonary tumors with volume helical shuttle technique:correlation of functional parameters with histopathological type and endothelial cell growth factor

Objective To investigate the value of first-pass perfusion CT with volume helical shuttle technique in the assessment of tumor perfusion in patients with pulmonary tumors,and to assess the correlation of functional parameters with histopathological type and Endothelial Cell Growth Factor (EGFR).MethodMethods This prospective study was approved by the institutional review board,and written informed consent was obtained from 41 consecutive patients with 50 primary pulmonary tumors.
