| 中文摘要:目的 总结肺撕裂伤的影像学特征及损伤机制、演变规律。方法 选取符合标准的肺撕裂伤患者32位患者48处病灶的CT图像进行回顾性分析。结果 圆形/类圆形组病灶与不规则形组病灶分布差异有统计学意义(P<0.05);并不是所有的病例,都必须经过气囊、气液囊、血肿3个阶段;32处病灶靠近胸膜下,16处位于非胸膜下,比较不同演变形式肺撕裂伤病灶的分布情况,差异无统计学意义(P>0.05);肺组织实变加重可使病灶缩小或消失;所有病灶复查中均未继续增大。结论 肺撕裂伤的3个演变形式为气囊、气液囊、血肿,256层螺旋CT及其后处理技术可以较好的观察肺撕裂伤的形态分布等特征,对于及时正确诊断具有重要价值。 |

| Abstract:Objective To evaluate the imaging characteristics and the damage mechanism and evolution of lung laceration. Methods Standard pulmonary lacerations from 32 patients were chosen and CT images of 48 lesions were analyzed retrospectively. Results Significant differences distribute between round/round-like lesion group and irregular group (P<0.05). Not all cases must be approved by the balloon, gas liquid capsule, and hematoma. Thirty-two cases were close to the pleura, and 16 cases were in non subpleural. There were no significant differences in comparing the distribution between different evolutions of lung laceration lesion (P>0.05). Lesions will either shrink or disappear with the increase of lung tissue consolidation. All lesions in the revision did not show any sign of continuing to increase. Conclusion Three stages of lung laceration will be envolved as the balloon, the gas-liquid capsule, and hematoma. Totally 256-slice spiral CT and post processing technology can be used to observe the laceration of lung morphology distribution, and has significant value in the diagnosis timely and correctly. |
