CT combined with real-time ultrasound for guiding percutaneous biopsy of pleural or subpleural nodule / 中国医学影像技术

ABSTRACT

Objective: To explore the feasibility of CT combined with real-time ultrasound for guiding percutaneous needle biopsy of small pleural or peripleural nodule (SPPN). Methods: Data of 38 patients with SPPN who underwent percutaneous biopsy were retrospectively analyzed, including 17 patients underwent CT combined with ultrasound-guided biopsy (CT+US group) and 21 patients underwent CT-guided biopsy (CT group). The operation time, occupation time, the number of CT guidance, effective radiation dose generated by CT scan and postoperative complications were compared between 2 groups. Results: Compared with those of CT group, the number of CT guidance, operation time, occupation time and effective radiation dose in CT+US group were lower (all P 0.05). Conclusion: CT combined with real-time ultrasound guidance can reduce the technical difficulty of puncture, shorten the operation time and reduce radiation dose during percutaneous needle biopsy of SPPN.
