摘要
目的 以常规门静脉直接造影为标准 ,对比分析螺旋CT与MR门静脉成像的临床应用价值。方法 3 8例患者分别进行了螺旋CT门静脉成像 (spiralCTportography ,CTP) ,三维动态增强磁共振血管成像 (3DdynamiccontrastenhancedMRangiography ,3DDCEMRA)和常规门静脉直接造影 ,间隔时间为 0～ 3d。其中 2 9例为肝癌患者 ,伴或不伴门脉高压 ;9例为单纯肝硬化伴门脉高压患者。以常规门静脉直接造影结果为标准 ,对照分析CTP和 3DDCEMRA对门静脉病变的显示能力 ,包括 :(1)门静脉成像质量 ;(2 )门静脉主干及左、右分支的开放性 ;(3 )侧支循环发生的部位及分布的范围 ;(4)分别计算 2种检查技术的平均费用。结果 CTP门静脉显影质量的总得分为 617,3DDCEMRA为60 0 ,经配对t检验 ,两者之间的差别无显著意义 (t=1 5 61,P >0 0 5 )。CTP和 3DDCEMRA与常规门静脉直接造影对照显示门静脉开放性的总符合率分别为 95 6% (10 9/114)和 96 5 % (110 /114) ,经 χ2检验 ,两者之间的差异无显著意义 (χ2 =0 814,P >0 0 5 )。除 1例冠状静脉曲张未显示外 ,其余侧支血管在CTP上均清楚显影 ,符合率为 97 1% (3 3 /3 4) ,而 3DDCEMRA漏诊 1例为脐静脉重新开放 ,其余均显示 ,符合率也为 97 1% (3 3 /3 4)。螺旋CT门静脉成像和
Objective To evaluate the clinical value of spiral CT portography (CTP) and 3D dynamic contrast enhanced MR angiography (3D DCEMRA) correlating with conventional portography (CP) Methods Thirty eight patients underwent CTP, 3D DCEMRA, and CP with interval of 0-3 days The clinical value of CTP and 3D DCEMRA was analyzed and compared with the golden standard of CP, including: (1) the imaging quality of portal vein; (2) the patency of the portal vein; (3) the distribution and extent of collaterals; (4) the average charge of both exams Results The total score of imaging quality of the portal vein shown by CTP was 617 correspondent with that of 3D DCEMRA (602) ( t =1 561, P >0 05) The percentage of agreement in the demonstration of the patency of the portal vein between CTP and CP and between 3D DCEMRA and CP was 95 6%(109/114)and 96 5%(110/114), respectively (χ 2=0 814, P >0 05) The percentage of agreement in each method in dimensioning the collaterals reached 97 1%(33/34)comparing with CP The average charge of both exams was $991 and $1 341, respectively Conclusion Both methods of CTP and 3D DCEMRA can well determine the portal venous patency and the existence of varices, and well correlate with the conventional portography CP would be replaced in a great extent by non invasive technology in the future
