Abstract: Objective To evaluate the application of MSCT perfusion imaging (PI)in diagnosing solitary pulmonary nodule (SPN).Methods 60 patients with SPN diagnosed by pathology were divided into two groups.Study group (SG)included 32 patients with lung cancer,and control group (CG)included 28 patients with benign nodules.The patients of two groups underwent 64-slice spiral CT PI and routine contrast-enhanced scan (ES).PI parameters were compared between SG and CG.The diagnosis value of PI was compared with that of ES.Results Compared with CG,SG had markedly higher BV,BF,PS and lower MTT (all P <0.01).Compared with ES, PI was more sensitive in detecting lung cancer and had a higher accuracy in diagnosing SPN (P <0.01).Conclusion MSCT PI plays an important role in diagnosing SPN.
