ABSTRACT

Objective To investigate the clinical value of the 18F-FDG SPECT-CT combined with the image of CT in the diagnosis of lung cancer.Methods Retrospectively analysis images of 18F-FDG SPECT-CT and CT of 162 patients pulmonary tumor-like lesions from January 2013 to October 2013 were conducted.All the patients have been confirmed by the pathological mechanism or cytologic examination.Each patient has been firstly diagnosed by the 18F-FDG SPECT-CT along and then combined with the images of CT.The sensitive rate and the accurate rate of two methods were compared by x2 test.Results There were 40 benign lesions and 114 malignant ones in 162 patients.The sensitive rates of the two methods were 86.0％ and 96.5％ (x2 =6.63,P ＜ 0.05).The accurate rates of the two ways were 79％ and 96.3％ (x2 =7.76,P ＜ 0.05).The differences were statistically significant.Conclusion 18F-FDG SPECT-CT combined with the images of CT can increase the diagnostic sensitivity and accuracy.It has important clinical value.
