摘要
目的探讨螺旋CT肋软骨成像方法及在诊断肋软骨疾病中的应用价值。方法对28例肋软骨病变组及200例对照组进行CT容积扫描,层厚1～7mm,层距1～2.5mm。将所有原始图像进行低对比及高对比薄层重建,然后将重建图像分别导入CT3D工作站进行MPR、MIP、SSD等方法重建,比较各种技术图像显示肋软骨的能力,并对肋软骨病变进行分析和记录。结果228例受检者的CT扫描图像经过MPR、MIP、SSD处理后均能显示出肋软骨,其中以MIP、SSD的效果较好;28例病变组中,发现肋软骨损伤13例,肋软骨炎9例,肋软骨畸形6例。结论螺旋CT图像能很好地显示肋软骨,为在活体上研究肋软骨形态学开创了一条全新途径,是一种无创伤性研究肋软骨疾病的最佳影像学方法。
Objective To investigate the application value of spiral CT imaging in diagnosing costal cartilage diseases. Methods CT volume scan with 1～7mm layer thinkness and 1～2.5mm layer distance was performed in 28 cases of costal cartilage diseases and 200 cases of controls. All of the original images were processed to form the thin layer reconstruction of low contrast and high contrast, and then the reconstructed images were transmitted to CT 3D work-station to perform the image reconstruction by MPR, MIP and SSD methods. The ability of different image techniques in displaying costal cartilage was compared, and costal cartilage pathological changes were analyzed. Results The CT scanning images of 228 cases could display the costal cartilage after the management of MPR, MIP and SSD, and the images managed with MIP and SSD were better. Among 28 patients with costal cartilage diseases, 13 cases of costal cartilage damage,9 cases of costal cartilage inflammation and 6 cases of costal cartilage malformation were found. Conclusion Spiral CT image could display the costal cartilage perfectly, was a new means of researching costal cartilage morphology in living body, and was the best imaging technique of researching costal cartilage disease without trauma.
