Analysis of rib metastasis in patients with single or double rib lesions on bone scans.

(A) posterior rib lesions were more likely to be metastatic than anterior rib lesions; (B) The metastases rates of rib lesions located on ipsilateral, contralateral and bilateral sides were not significant different; (C) Concurrent lesions of rib and other site on bone scans were more likely to be rib metastatic than pure rib lesions.
