Objective:To research the value of diagnosis of traumatic rib fractures by multislice CT VRT and DR plain film. Methods: Seventy-two cases of traumatic rib fracture patients were diagnosed by DR film and multislice CT VRT. Results:Multiple rib fractures than single, most of them occurred in the 4-10 ribs and axillary segment, 97.2%of 16-slice spiral CT three-dimensional reconstruction of patients with rib fracture diagnosis rate significantly higher than DR plain film diagnosis rate 80.3%(x2=19.15, P<0.01), DR plain film missed rib fractures are mainly located in the costal cartilage (58.1%), 16-slice spiral CT reconstruction is still found 19 other fractures and lung complications 16cases. Conclusion:16-slice CT the thin layer VRT diagnosis of rib fractures greatly improves the diagnostic accuracy.

Regional saturation technique has been applied in MR scaning widely. It is possible to obtain MRA or MRV by putting the REST slab on one side of slice or another. REST eliminates artifacts caused by motion or blood flow and minimizers wrap artifacts along the phase encoding and high quality of images can be provided.
