To evaluate the portal and arterial blood supplies to dysplastic nodules in the cirrhotic liver with computed tomography (CT) during arterial portography (CTAP) and CT hepatic arteriography (CTHA).
Nineteen histopathologically proved low-grade dysplastic nodules and 13 high-grade dysplastic nodules in 17 patients with liver cirrhosis were evaluated with CTAP and CTHA for the presence of portal and arterial blood supplies to the nodules. The nodules ranged from 0.4 to 4.5 cm in diameter (mean, 1.6 cm).
The portal supply was present in 14 of the 19 (74%) low-grade dysplastic nodules and in seven of the 13 (54%) high-grade dysplastic nodules. The hepatic arterial supply was increased in four of the 19 (21%) low-grade dysplastic nodules, present in nine (47%), and absent in six (32%). The arterial supply was increased in four of the 13 (31%) high-grade dysplastic nodules, present in four (31%), and absent in five (38%).
The portal and arterial supplies to the low- and high-grade dysplastic nodules were variable and inconsistent. Therefore, it is difficult to detect and characterize the dysplastic nodules on the radiologic images on the basis of the blood supply.
在动脉门静脉造影（CTAP）和CT肝动脉造影（CTHA）期间，用计算机断层扫描（CT）评估肝硬化肝脏发育异常结节的门静脉和动脉血供情况。
对17例肝硬化患者的19个经组织病理学证实的低级别发育异常结节和13个高级别发育异常结节进行CTAP和CTHA检查，以评估结节的门静脉和动脉血供情况。这些结节直径为0.4至4.5厘米（平均1.6厘米）。
19个低级别发育异常结节中有14个（74%）存在门静脉供血，13个高级别发育异常结节中有7个（54%）存在门静脉供血。19个低级别发育异常结节中有4个（21%）肝动脉供血增加，9个（47%）存在肝动脉供血，6个（32%）无肝动脉供血。13个高级别发育异常结节中有4个（31%）肝动脉供血增加，4个（31%）存在肝动脉供血，5个（38%）无肝动脉供血。
低级别和高级别发育异常结节的门静脉和动脉供血情况各不相同且不一致。因此，很难根据血供情况在放射影像上检测和鉴别发育异常结节。
