Perfusion CT (PCT) is a method used for the assessment of microvascularisation. In liver it enables to evaluate not only total perfusion, but also to distinguish between it's arterial and portal component. Thanks to this possibility is this method able to evaluate neoangiogenesis in tumorous tissue and it's reaction to the therapy. It is also contributing in the diagnostics of chronic heepatopathies. Substantial qualitative shift arose after introduction of multidector computed tomography with high number of detector rows, that allows to examine the whole volume of the liver and so perfusion CT can be utilized not only for more detailed evaluation of known tumors but also for their detection.
