Study on Clinical Application of CT-guided Percutaneous Puncture Biopsy of Pulmonary Masses / 实用放射学杂志

ABSTRACT

Objective To explore the clinical application and the relative factors that effect on the diagnostic accuracy in CT-guided percutaneous puncture biopsy(PPB) of pulmonary masses.Methods PPB in 72 cases with pulmonary masses were performed.The results ofsurgery,pathology, image,and the relative factors that effect on the diagnostic accuracy of PPB were analyzed.Results The punctureaccuracy was 100%,the diagnostic accuracy was 89.6%(61/72),the rate of complication was 11.1%(8/72) in CT-guided percutaneous puncture biopsy of pulmonary masses.The determining factors that effect on the diagnostic accuracy and the rate of complication were age of patients,present of emphysema,size and internal content of pulmonary masses in CT-guided percutaneous puncture biopsy.Conclusion CT-guided percutaneous puncture biopsy was a safe,accurate and simple mean of diagnosis and differential diagnosis for pulmonary masses.To improve the accuracy and reduce complication ,the related factors of patients ,lesion,and the technique should be attended.
