OBJECTIVE
This study investigated the findings revealed by dynamic helical CT of proximal arterioportal shunting associated with hepatocellular carcinoma. We also evaluated the diagnostic capability of this imaging technique to reveal the mass in patients with hepatocellular carcinoma.
CONCLUSION
On dynamic helical CT, proximal arterioportal shunting altered liver perfusion and tumor enhancement. Heterogeneous enhancement of liver parenchyma and decreased enhancement of hepatomas diminished diagnostic capability on the arterial dominant phase image. However, with the addition of imaging in the arterial portal phase, lesion conspicuity improved.
目的
本研究调查了肝细胞癌相关的近端动门脉分流在动态螺旋CT上的表现。我们还评估了这种成像技术对肝细胞癌患者肿块的诊断能力。
结论
在动态螺旋CT上，近端动门脉分流改变了肝脏灌注和肿瘤强化。肝实质的不均匀强化和肝癌强化的降低削弱了动脉期图像的诊断能力。然而，增加动脉门静脉期成像后，病变的清晰度得到了改善。
