Methods 27 patients with suspected thoracic tumors, CT showed that the diameter of the lesion was 0.7-4.8 cm, with an average of 1.8 cm. All biopsies were taken under the guidance of spiral CT stereotactic positioning. Among them, 15 cases had severe chronic obstructive pulmonary disease (COPD), 1 case had pleurisy and old tuberculosis, and 1 case had coagulopathy. A 25G biopsy needle is used for the puncture, and a coaxial cannula is sheathed for percutaneous biopsy.
