| 目的 收集整理2012年1月～2013年12月我院收治的重症多发性肋骨骨折患者临床资料,分析并探讨320排螺旋CT在多发性肋骨骨折诊断中的临床应用价值。方法 对86例多发性肋骨骨折的患者进行320排螺旋CT扫描,重建全肋骨三维图像,并与胸部X线检查和普通螺旋CT的三维重建图像进行分析比较。结果 所有患者均顺利完成320排螺旋CT扫描,扫描时间均在3~5 s以内。与普通螺旋CT相比,320排螺旋CT重建的三维图像更加清晰细腻,且在线性骨折、凹陷性骨折以及肋软骨骨折的显示上存在显著统计学差异(p < 0.01)。结论 相对于普通螺旋CT,320排螺旋CT具有扫描速度更快、放射剂量更低、图像质量更好等特点,在一定程度上提高了肋骨骨折检出率,使诊断的准确性更高,具有明显的优势。 |

| Abstract: |
| Objecive To evaluate the clinic value of 320 rows spiral CT in diagnosis of rib fractures. Methods Eighty-six patients with rib fractures were examined by 320 rows spiral CT. After the scanning, rib three-dimensional reconstructions were carried out. The number of ribs fractures was compared with that demonstrated by X-ray and common spiral CT. Results All patients were examined successfully in 3~5 seconds. The images quality of ribs reconstructed by the new method was excellent and exquisite. Many linear fractures and depressed fractures and costobrachial fractures which were not displayed in the images reconstructed by common spiral CT were displayed. The difference was significant statistically. Conclusion Compared with common spiral CT, 320 rows spiral is superior, with faster scanning speed, lower radiological dose and better image quality, improving the diagnostic accuracy of rib fractures to some extent. Therefore, it is an advanced and reliable diagnostic tool for rib fractures. |
