Experiments on rabbits with implanted liver tumours have shown that iso-dense tumours, which are not visible on CT, may be demonstrated by dynamic CT following intravenous contrast injection. They may appear as hypodense areas during a period of maximal organ perfusion, if the tumours have not taken up the contrast. The ability to recognise tumours depends largely on intravascular and, only to a smaller extent, on interstitial contrast enhancement.
对植入肝肿瘤的兔子进行的实验表明，CT上不可见的等密度肿瘤在静脉注射造影剂后通过动态CT可能显示出来。如果肿瘤未摄取造影剂，在器官灌注最大的时期它们可能表现为低密度区域。识别肿瘤的能力很大程度上取决于血管内造影剂增强，仅在较小程度上取决于间质造影剂增强。
