【摘要】 目的 探讨腹腔动脉造影CT对肝脏占位性病变的诊断价值。方法 对35例疑为肝脏恶性肿瘤的占位性病变进行腹腔动脉造影CT检查,并比较动、门脉期显示病灶的数目及影像学特征。结果 在44个原发性肝癌灶中,经腹腔动脉造影CT动脉期发现31个,门脉期发现39个,动脉期结合门脉期发现40个。4个门脉期异常灌注灶动脉期及手术均未发现异常。5例肝硬变伴瘤样增生动脉期均可显示,其中4例门脉期未见异常灌注。结论 经腹腔动脉造影门脉期较动脉期发现更多的癌灶,但特异性较低,二者结合可提高癌灶的检出率。肝硬化伴瘤样增生可通过结合动脉期及门脉期的表现作出诊断。更多还原

【Abstract】 Purpose To explore the diagnostic value of CT angiography by coeliac axis. Methods Angiographic CT enhancement were performed in 35 hepatic space - occupying lesions. Results In 44 primary hepatic carcinoma lesions, 31 were shown in arterial phase, 39 were shown in portal venous phase, and 40 were shown in arterial & portal venous phase. 5 adenomatous hyperplasias lesions in cirrhotic liver were shown in arterial phase, only 1 of them was shown in portal venous phase. Conclusion Combination of arterial and portal venous CT enhancement by coeliac axis is valuable for diagnosis of hepatic space - occupying lesions.更多还原
