Abstract：Objective: To analyse and compare the value of different modalities of radiologic imaging for rib metastasis. Methods: Thirty-eight patients with rib metastasis were examined: 17 cases were examined by plain films, 21 cases underwent CR, 7 cases underwent chest SCT and thin slice reconstruction, 6 cases underwent thin slice SCT and 7 cases slope scanning; 18 cases underwent chest MSCT and thin slice reconstruction, 2D MPR, 3D VR and 3D MIP respectively. Results: In 38 rib metastases, X-ray film and CR demonstrate the location accurately and diagnostic accuracy was 71.0% and 74.3% respectively. There was no difference between them(P>0.05); Image of SCT and MSCT could demonstrate small rib disease and diagnostic accuracy was 91.0% and 92.6% respectively. There is significant difference between CT and X-ray film or CT and CR(P<0.05). Diagnostic accuracy of thin slice image is 100%, so it is used as contrast standard. 2D MPR play an assistant role to transverse image in diagnosis; 3D image could demonstrate the bony of thorax fully, so the location is clear and lesion could be viewed easily. Conclusion: SCT, MSCT, 2D and 3D reconstruction imaging have distinctive advantage in diagnosing rib metastasis, combination of conventional radiography and CR, diagnosing the character and location of the rib metastasis is the best.
