Results: 86 cases with DR radiography in the diagnosis of pulmonary contusion, fractured ribs, 312, 16 cases not seen obvious abnormity; CT three-dimensional imaging in the diagnosis of pulmonary contusion, 103 cases, 324 of rib fractures, 6 cases no exception. Conclusion: routine chest X-ray examination is an important means of diagnosis of chest injury, with its low cost, convenient check, become the preferred check project. But a low resolution of the sternum with its density, image overlap, lesion location is not accurate, and cortical folds rib injury is not easy to find the deficiency, row CT scan in time, can make up for the inadequacy of plain film, for the early diagnosis of pulmonary contusion and fractured ribs provide more infor
