PDFAbstract
Objective To explore the application value of multi-slice spiral CT (MSCT) three-dimensional (3D) bone reconstruction on the diagnosis of rib and rib cartilage fractures. Methods Forty-three cases of patients with chest injury were treated as the study objects. All of them underwent multi-slice spiral CT scanning. Volume rendering (VR), maximum intensity projection (MIP) and multi planar reconstruction (MPR) were used for 3D reconstruction of ribs and rib cartilage. Compared with routine CT scan, the diagnostic advantages of MSCT 3D reconstruction were analyzed. Results Fortythree cases had rib fractures, a total of 122 ribs. Single fractures accounted for 30.23% and multiple fractures accounted for 69.77%; The axillary segment of rib fracture was common, accounting for 95.65%, 15 cases had rib cartilage fractures, a total of 23, 24 cases were detected with complications by MSCT. The accuracy rate of MSCT 3D reconstruction in the diagnosis of rib and rib cartilage fractures (98.36%, 95.65%) were significantly higher than those of CT scan (72.95%, 13.04%) (P＜0.05). Conclusion The accuracy of MSCT in the diagnosis of rib and cartilage fractures is high. It can be used as an ideal imaging method for the diagnosis of the disease.
