To evaluate the effect of coaxial needle size on pneumothorax rate and the diagnostic accuracy of computed tomography (CT)-guided transthoracic needle aspiration biopsy (TNAB) of pulmonary nodules. ⋯ Use of a smaller coaxial stabilizing needle produces a substantially decreased risk of pneumothorax with comparable diagnostic accuracy, sensitivity, and specificity for histopathologic diagnosis of pulmonary nodules.

For the treatment of lytic disease involving the pedicles of vertebrae in patients with metastatic disease, the authors performed percutaneous vertebroplasty by using an access route via the lysed pedicle. Fifty-one pedicles were treated in 32 consecutive patients. In all cases, a radiologically satisfactory filling of both the affected pedicle and the vertebral body was achieved. Clinically effective pain relief was obtained in 24 (75%) of 32 patients, and no clinical complications were observed.
