胸部创伤X线-CT诊断

本文对临床资料完整的５０例胸部创伤进行了Ｘ线与ＣＴ检查的对比分析，着重讨论了闭合性及开放性胸部创伤的ＣＴ征象。作者观察到Ｘ线检查在反映胸部全貌，肋骨骨折时优于ＣＴ扫描，而对Ｘ线未能发现的肺轻度挫伤、出血、少量气胸、心包积液、膈疝等，ＣＴ能做出明确诊断；还发现Ｘ线片所见到的脊柱旁长条状“纵膈气肿”实为脊柱旁的气胸影象。对Ｘ线检出的胸部阴影不能定性的，ＣＴ能区别为肺挫伤、肺血肿、肺囊肿、胸壁血肿等病变，为临床提供了较平片更加准确的放射诊断。对合并肝、脾、肾、肠等腹部脏器破裂的复合伤及骨盆、脊椎骨折等也可快速完成

X Ray and CT Diagnosis of Chest Injury

cases with complete clinical x ray and CT materials of chest injury are analysed in this paper. The CT appearances of closed and open chest injury are emphatically discussed. The author considers that X Ray examination is better than CT only on observing full view of chest and fracture of rib. But CT examination can make out definite diagnosis on pulmonary contusion, bleeding, little pneumatothorax, cardic effusion, diaphragmatocele and so on, that can't be found by X Ray. The paravertebral microscler mediastinal emphysema on X Ray is proved to be paravertebral pneumothorax by CT. CT examination can also distinguish among pulmonary contusion, hematoma, cyst and hematoma of chest wall that X Ray can't determine the nature. CT can provide more information and evidence to clinical diagnosis than X Ray. Abdominal visceral injury and the fracture of pelvis and spine can be examined quickly by CT.
