Abstract: Sixty-four patients with solitary pulmonary nodules were included in this study. The diameter of pulmonary nodules was equal or less than 3.0 cm and no contact with the adjacent pleura. They were divided into study group( with acuductor locating method)and conventional group (with conventional method). The results showed that the one-time success rates were 97％ (31/32)in study group and 72％(23/32) in conventional group, the diagnostic accuracy were 94％ ( 30/32 ) and 88 ％ ( 28/32 ), respectively,while the successful puncture time were( 13. 5 ±4. 9)min and( 18. 7 ±5. 7) min, respectively. In study group,the complication rate was 9％ (3/32), while 28％ ( 9/32 ) in conventional group. There were statistical differences between the two groups. CT-guided aspriation biopsy for solitary pulmonary nodules with self-made acuductor can obviously improve one-time success rate and reduce the complication rate and operative time.
