Objective To explore the diagnostic value of CT-guided percutaneous needle aspiration biopsy (PTNB) for ground-glass opacity (GGO) pulmonary lesions. Methods A retrospective design was used to collect clinical data of patients with GGO lesions admitted in the Affiliated Hospital of North Sichuan Medical College between Jan. 2009 to Jan 2015. Patients were divided into groups according the lesion size (≤10 mm, 10-20 mm,≥20 mm), length of needle path (≤5 cm, 5-9 cm,≥9 cm) and percentage of GGO component (50%-90%, >90%), respectively. The total and subgroups of sensitivity, specificity, and diagnostic accuracy of CT guided PTNB for diagnosing GGO were calculated and the differences among subgroups were compared using Fisher's exact test. Statistical analysis was conducted by using SPSS 17.0 software. Results A total of 60 patients involving 48 malignant and 12 benign lesions were included. The total sensitivity, specificity, and accuracy of CT guided PTNB for diagnosing GGO were 87.5%, 100% and 90%, respectively. There were no significant differences among the subgroups based on the lesion size, length of needle path, and percentage of GGO component (all P values >0.05). Conclusion CT-guided PTNB can be used as one of the diagnostic modalities for lung GGO lesions with a moderate diagnostic value.
