多层螺旋CT重建技术在胸骨及肋软骨骨折中的应用

Application of multi slice spiral CT reconstruction technique in the fracture of the bone and rib cartilage

目的分析多层螺旋CT重建技术在胸骨及肋软骨骨折中的应用。方法回顾分析胸骨骨折10例、肋软骨骨折16例患者,在工作站进行多种后处理重建,主要有1mm薄层横断图像重建,多平面重组(MPR)、曲面重建(CPR)、最大密度投影法(MIP)、容积再现技术(VR)重建,并与X线胸片对比。结果 10例胸骨骨折患者,其中胸骨柄骨折3例,胸骨体骨折7例;16例肋软骨骨折患者,单根肋软骨骨折12例,多根肋软骨骨折4例。其中X线胸片显示胸骨骨折8例,肋软骨骨折0例;16层螺旋CT多种重建技术优于X线检查结果。结论多层螺旋CT重建技术综合应用可为胸骨及肋软骨骨折患者提供可靠的影像学依据,在临床诊治中具有重要的应用价值。

Objective To discuss the application of multi slice spira CT reconstruction technology application in the sternum and costal cartilage fracture. Methods Retrospectively analyzed 10 cases of sternal fracture,costal cartilage fracture 16 patients. A variety of post-processing reconstruction in the workstation,mainly had 1 mm thin layer cross sectional image re-construction,multiplanar reconstruction(MPR),curved surface reconstruction(CPR),maximum density projection(MIP),vol-ume representation technology(VR)reconstruction,and compared with X-ray chest radiography. Results 10 cases of sternal fracture patients,the manubrium of sternum fracture in 3 cases,body of sternum fracture in 7 cases;16 cases of costal cartilage fracture patients,12 cases of single rib cartilage fracture,4 cases of multiple root costal cartilage fracture. X-ray revealed 8 ca-ses of chest X-ray,0 cases of rib cartilage fracture;16 layers spiral CT multiple reconstruction technology was superior to a vari-ety of X-ray examination results. Conclusion The integrated application of multi slice spira CT reconstruction technology can provide the sternum and costal cartilage fracture patients with reliable imaging basis,has important application value in clinical diagnosis and therapy.
