Abstract:
Objective To investigate the clinical value of PET-CT in aiding CT guided percutaneous puncture biopsy for lung mas-ses.Methods The retrospective data were analyzed including 5 7 patients with lung masses who underwent CT guided percutaneous puncture biopsy combined with PET-CT (regarded as a research group)and other 75 similar patients with single CT-guided biopsy (control group).In two groups,it was divided with malignant,suspicious malignant,can not be diagnosed,inflammatory,benign by pathological findings,and was contrasted with the surgical pathology or final clinical results.To calculate sensitivity,specificity and accuracy of diagnosis for cancer through two puncture method.Recorded complication for pneumothorax and bleeding in two groups .Be compared analysis using the 2 test.Results In study group,it was higher for the diagnosis of malignancy sensitivity, specificity,accuracy.There were 96.3% (52/54),100.0%(3/3)and 96.5%(55/57)in research group,while those were 88.4%(61/69),83.3% (5/6)and 88.0% (66/75)in the control group,respectively.And no statistically significant.Between research and the control group,there was a significantly statistical difference in the rate of twice punctures in one mass (χ2= 10.122,P=0.001).Between the two groups,there was no statistically significant difference in the pneumothorax rate and the hemorrhage rate. Conclusion PET-CT in aiding CT-guided lung biopsy improves the sensitivity,specificity and accuracy of diagnosis.
