【摘要】 目的:探讨螺旋CT扫描三维成像技术在临床疾病中的应用价值。方法:对于53例病人行螺旋CT薄层扫描,重叠重建(层厚3～5 m m ,间隔1～2.5 m m ),然后通过软件功能行三维重建(three- dim ensionalreconstruction,3D)。通过旋转三维图像从最佳角度来观察病变的立体形态及其周围结构关系。结果:外伤31 例,肿瘤6例,感染5 例,骨关节退行性变5例,先天畸形4 例,胆囊息肉1例,正常结肠1例。结论:螺旋CT扫描三维重建(3DCT)可作为横轴图像和二维重建图像的重要补充,它可更直观地显示病变的立体形态。对于骨外科、口腔颌面外科手术前制定治疗计划和术前、术后对比均有重要的指导作用更多还原

【Abstract】 Objective:To discuss the value of clinical application of 3-dimensional reconstruction techniques in diseases.Methods:53 patients underwent thin slice scan with spiral CT.The obtained images were processed through overlapping reconstruction consequently.Then through softwere functions 3-dimensional reconstruction was completed.By rotation of a 3-dimensional image to observe it at an any angle,we could make clear the stereofigure of a lesion and its relations with the surrounding structures.Results:3-dimensional CT images of 53 cases were analyzed,including trauma(31 cases),tumor(6 cases),infection(5 cases),retrograde affection of bone and joint diseases(5 cases),congenital deformity(4 cases),polip of gallbladder(1 case)and nomal colon(1 case).Conclusion:The 3-dimensional image can be a supplement of an axial and 2-dimensional CT image.By rotating it,we can observing the stereofigure of a lesion and its relations with the surrounding structions from an any angle.And it is an important guidance in making appropriate surgical treatment plans before the operations of skeletal and maxillofacial surgery and comparing preoperation with postoperation of disease.更多还原
