摘　　要：目的:讨论多层螺旋CT(MSCT)的重建技术在胸部创伤中的临床应用。方法:对78例胸部创伤病人的MSCT进行多平面重建(MPR)、滑动薄层块最大密度投影(STS-MIP)、容积再现(VR)。然后比较重建前与重建后MSCT对胸部创伤病变检出率和诊断正确性的差异。结果:78例胸部创伤中肺挫伤42例,肺撕裂伤5例,肺不张13例,气胸29例,胸腔积液46例,心包积液2例,纵隔气肿3例,肋骨骨折58例,肩胛骨骨折10例,锁骨骨折7例,胸骨骨折2例,胸椎骨折4例。其中2例肋骨骨折、1例锁骨骨折和1例胸骨骨折MSCT图像重建前漏诊,漏诊率为6.9%,1例膈疝误诊为肺部不张。结论:多层螺旋CT重建技术在胸部创伤中是一种可靠的诊断方法,结合原始图像能更正确和更直观地为临床诊治提供依据。[Objective]Discussion of multi-slice CT(MSCT) and reconstruction in the clinical application of thoracic trauma. [Method]Retrospectively analyze 78 cases of chest trauma patients with MSCT complete information,Reconstruction for multi-planar reconstruction(MPR),Block sliding thin maximum intensity projection(STS-M IP) and Volume rendering(VR). [Result]78 cases of chest trauma,including 42 cases of pulmonary contusion,5 cases of lung laceration,Atelectasis and pulmonary atrophy in 13 cases,Pneumothorax in 29 cases,46 cases of pleural effusion,Pericardial effusion in 2 cases,3 cases of mediastinal emphysema,58 cases of rib fracture,Scapular fractures in 10 cases,Clavicle fracture in 7 cases,Sternum fracture in 2 cases,4 cases of thoracic fractures.[Conclusion]Multi-slice CT reconstruction in thoracic trauma is a timely and reliable inspection and can provide a reliable basis for clinical diagnosis and treatment.
