Abstract:
Objective: To explore the application value of multi-slice spiral CT based on low dose technique in diagnosis of rib fracture. Methods: 58 patients with highly suspected rib fracture patients were examined by DR and multi-slice spiral CT. 3D reconstruction were finished after MSCT examination at the workstation, including MPR(multi-planar reconstruction), and volume rendering technique(VR). And the results were compared between DR and CT. Results:58 patients all successfully completed the chest X-ray film and multi-slice spiral CT examination. Multi-slice spiral CT image quality fully met the requirements of clinic. It can not only diagnose, but also display the number, location and morphology of rib fracture. 45 cases were diagnosed with chest DR rib fracture and suspected fracture, and the positive rate was 77.59%(45/58). 56 cases were definitely diagnosed with multi-slice spiral CT scanning and three-dimensional reconstruction rib fracture, and the positive rate was 96.55%. Conclusion: The patients can receive lower dose and the tube can be used for a longer time by low dose technique. 3D reconstruction techniques of multi-slice spiral CT not only improve the accuracy of diagnosis, but also display rib fracture morphology clearly, so its clinical value is much higher than DR.
