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 explore spiral CT imaging of cartilage imaging and its value in the diagnosis of costal cartilage diseases. Methods 28 cases of costal cartilage disease group and 200 cases of control group CT volume scanning, layer thickness 1 ~ 7mm, layer spacing 1 ~ 2.5mm. All the original images were reconstructed by low-contrast and high-contrast thin layers. Then the reconstructed images were imported into CT3D workstation and reconstructed by MPR, MIP and SSD respectively. The ability of various technical images to show costal cartilage was compared and the costal cartilage lesions were analyzed And record. Results The CT scan images of 228 subjects showed cartilage after MPR, MIP and SSD treatment, and MIP and SSD were the better ones. Among 28 lesions, 13 cases of costal cartilage injury, 9 cases of inflammation, costal cartilage deformity in 6 cases. Conclusion Spiral CT images of costal cartilage can be well displayed. It provides a new way to study the morphology of costal cartilage in vivo. It is a noninvasive imaging method to evaluate costal cartilage disease.
