【摘要】 目的探讨双源CT门静脉血管成像的临床应用价值。方法对21例正常者及43例门静脉病变者以小剂量预注射法行双源CT门静脉血管成像,观察分析门静脉分支情况和门静脉病变的影像学特征。结果正常组21例均可清楚观察到门静脉1-5级血管结构,病变组门静脉高压伴静脉曲张28例,门静脉海绵样变4例,门静脉栓子9例(其中1例伴肝动脉-门静脉瘘),肝移植术后门静脉狭窄2例。结论双源CT门静脉血管成像是门静脉无创性检查的可靠方法,具有一定的临床应用价值。更多还原

【Abstract】 Objective To evaluate the clinical value of portography with dual-source CT.Methods 21 normal people and 43 cases with portal vein diseases had were performed dual-source CT portography by Test Bolus respectively.The grades of normal portal vein and the feature of portal vein diseases were analyzed.Results The normal group 1-5 grade structure of portal vein could be clearly displayed,28 cases portal hypertension with varix,4 cases cavernous transformation of portal vein,9 cases portal vein embolism,(1 cases of them had hepatic artery-portal fistula),2 cases portal vein stenosis after liver transplantation.Conclusion The portography of dual-source CT is reliable and has no traumatic method examining portal vein.The method has certain clinical application values.更多还原
