摘　　要：目的:探讨16排螺旋CT三维及最大密度重建技术在肝癌动门脉分流诊断中的应用价值。方法:对64例肝癌伴动门脉分流患者的16排螺旋CT增强图像进行三维及最大密度重建,并对重建图像进行观察和分析(与CT轴位图像和数字减影血管造影图像进行对照)。结果:16排螺旋CT三维及最大密度重建技术能全面、直观、多方位地显示肝癌动门脉分流的影像征象,并能较好显示动门脉分流导致的血液动力学改变。结论:16排螺旋CT三维及最大密度重建作为轴位CT图像的重要后处理技术,具有无创、直观、快速显示肝癌动门脉分流各种影像征象的特点,为临床诊断和治疗肝癌动门脉分流提供可靠的依据。Objective: To investigate the clinical applicable value of three-dimensional(3D) and maximum intensity projection(MIP) with 16-row helical CT in diagnosing the hepatic carcinoma with arterioportal shunt.Methods: 64 Cases of hepatic carcinoma with arterioportal shunt underwent 16-row helical CT enhanced volume scans.To be reconstructed with MIP and 3D techniques,All reconstructed imagines were observed and analysed(compaired with imagines of trans-axia and DSA).Results: 16-row helical CT MIP and 3D reconstruction could produce clear and comprehensive images of the hepatic carcinoma with arterioportal shunt,and produce the change of hemodynamics which resulted in arterioportal shunt.Conclusion: 16-row helical CT MIP and 3D reconstruction as important techniques of trans-axial,could display the characteristical of the hepatic carcinoma with arterioportal shunt with no traumatic,intuitionistic and quickly,which could afford the powerful evidence for clinical diagnose and treat with the hepatic carcinoma with arterioportal shunt.
