螺旋CT三维图像重建在诊断软组织肿瘤中的应用研究

Research on the three-dimensional image reconstruction of spiral CT application in the diagnosis of soft tissue tumors

目的:探讨螺旋CT三维图像重建对诊断软组织肿瘤的临床价值。方法:收治软组织肿瘤患者30例,采用MRI检查10例,行螺旋CT血管造影并进行三维图像重建(MM3DR)检查20例。结果:20例患者行螺旋CT血管造影及MM3DR检查,共确诊16例,诊断符合率80.0%,10例患者行MRI检查,共确诊7例,诊断符合率70.0%,两组比较差异有统计学意义(P<0.05);在病灶轮廓和血管状况图像方面,螺旋CT血管造影及MM3DR检查明显优于MRI组,两组比较差异有统计学意义(P<0.05)。结论:螺旋CT三维图像重建在诊断软组织肿瘤时病灶血管、病灶周围比较清晰,易于诊断,优于MRI检查。

Objective:To investigate the clinical value of three-dimensional image reconstruction of spiral CT in diagnosis of soft tissue tumors.Methods:30 patients with soft tissue tumors were selected,10 cases with MRI examination,20 cases with spiral CT angiography and three-dimensional image reconstruction(MM3DR)examination.Results:In 20 patients with spiral CT angiography and MM3DR examination,16 cases were diagnosed,and the diagnostic accordance rate was 80%.In 10 patients with MRI examination,7 cases were diagnosed,the diagnostic accordance rate was 70%,the difference was statistically significant between two groups(P<0.05),The focus contour and vascular images in the group with spiral CT angiography and MM3DR examination is better than in the group with MRI,and the difference was statistically significant between two groups(P<0.05).Conclusion:Three-dimensional image reconstruction of spiral CT can show the lesion and vessel clearly in the diagnosis of soft tissue tumors,so it can be easy to diagnose,and better than MRI examination.
