Abstract:
Objective To assess the clinical diagnostic value of CT guided transthoracic core needle biopsy (TNB) in patients with pulmonary peripheral lesions. Methods The pathological findings, follow up results, mass size, complications due to paracentesis, and other examination results in 223 patients with pulmonary peripheral lesions undergoing TNB were analyzed retrospectively. Results The positive predictive value of malignant lesions was 100%. False negative was found in 3 cases. There was no false positive of malignant lesions in all the cases. The sensitivity and specificity were 93.6% and 100%, respectively. The negative predictive value of benign lesions was 94.8%. There was no significant difference in the satisfaction rate of multiple biopsy between the large and small nodules. The satisfaction rate of a single biopsy of the large nodule was significantly better than that of the small nodule ( P
