Abstract：Objective To study the clinical significance of applications of CT perfusion imaging in the diagnosis of lung cancer. Methods 34 patients with lung cancer, admitted in our hospital from September 2013 to September 2014, were chosen as the subject, who received CT scans before and after the chemoradiotherapy. The relevant perfusion parameters in patients with effective and ineffec-tive treatment were analyzed. Results After treatment, the effective perfusion value, strengthening amplitude and nodules - aortic strengthening value ratio were lower than those before treatment (P<0. 05). The indicators of ineffective treatment group were not sig-nificantly different (P>0. 05), and BV, BF and PS in effective group were lower than those in ineffective group (P<0. 05). MTT in effective group was higher than that in ineffective group (P<0. 05). Conclusion CT perfusion for patients with lung tumor can effec-tively manifest blood supply, high perfusion zone surrounding the tumor and biological behavior of tumor, so it is worthy of clinical pop-ularization and application.
