Abstract:
Objective To explore the value of 64-row helical CT multi-phase enhancement scan combined with angiography (CTA)in the diagnosis of pulmonary mass.Methods Two hundred and sixty-five patients with pulmonary mass confirmed by pa-thology were checked,analyzed the CT sign of multi-phase enhancement scan and the blood supply of pulmonary mass displayed by CTA.Results Lung cancer was mainly supplied by bronchial arteries,some by body arteries,the feeding arteries display rate of lung cancer group was significantly higher than that of benign disease group(P <0.05).CT enhancement peak value of lung cancer group was significantly higher than that of tuberculoma group,inflammatory pseudotumor group and hamartoma group(P <0.05), but no significant difference between hemanginoma group(P >0.05).Enhancement dynamic curves of lung cancer group was differ-ent from benign lesion groups:Lung cancer without obvious enhancement in pulmonary artery phase,CT value increased rapidly in aorta phase,120 s reached peak,and declined slowly in delay phase;CT value of tuberculoma was increased slowly without obvious peak;CT value of inflammatory increased gradually in pulmonary artery phase,90 s reached the peak;hamartoma was no obvious enhancement;Hemangioma enhanced rapidly after strengthening in the pulmonary artery phase,reached the peak at about 15 s,and then decreased slowly.Conclusion 64-row helical CT multi-phase enhancement scan combined with angiography have important clinical value,which can differentiate malignant mass from benign ones.
