[Animal experimental studies on the application of dynamic computed tomography to liver tumors].
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.
