摘要
目的了解胸部X线及CT检查对急性胸部创伤的诊断意义。方法回顾性分析217例急性胸部创伤患者的胸部X线和CT表现,对其诊断阳性率进行比较。结果肋骨、锁骨骨折X线阳性检出率高;胸壁血肿、纵隔及皮下气肿、气胸、血气胸、肺实质损伤、创伤性肺不张等均以CT阳性检出率高。结论急性胸部创伤的影像学改变多种多样。多种诊断方法相结合对提高诊断准确率很有帮助。
Objective To evaluate chest radiograph and CT scan in assessing acute thoracic trauma. Methods Retrospectively analyzed the findings of chest radiograph and CT scan in 217 cases of acute thoracic trauma and positive rate of each modality was compared. Results The positive rate of rib and clavicle fracture was higher in chest radioghraph than these in CT scan. But the positive rate of chest wall hematoma, mediastinum and subcutaneous emphysema, pneumothorax, hydropneumothorax, damage of lung parenchyma and traumatic pulmonary atelectasis was higher in CT scan than those in chest radiograph. Conclusion The application of the combined imaging modalities improves assessing of acute thoracic trauma, because the imaging manifestation of the lesion is various.
