近年来 ,肝脏的高分辨率CT和MR动态增强动脉期和门静脉期成像技术取得了快速发展。这种动态成像技术对肝脏病灶的检测和定性较一般的增强扫描更优越 ,尤其是对肝脏富血管性新生物。然而 ,对肝脏肿瘤的检测特别是HCC的检测仍然是具有挑战性的影像问题 ,尤其是在慢性肝病的时候[1
In recent years, high resolution CT and MR of the liver have been rapidly developed in arterial and portal venous imaging. This dynamic imaging of liver lesions detection and qualitative superior to the general enhanced scan is superior, especially for the liver of the new blood vessels. However, the detection of liver tumors, especially HCC, remains a challenging imaging problem, especially in chronic liver disease [1
