High resolution CT mammography of surgical biopsy specimens.

abstract：:We reviewed the CT of 20 patients with peripheral lung malignancies in which CT appearance suggested chest wall invasion on the basis of extension of mass around ribs into fat or muscle of the chest wall, or definite bone destruction. We correlated these findings with other radiographic studies and surgical and autops...
