The presence of peripheral periportal fibrosis, heterogeneity of hepatic parenchyma, and splenic siderotic nodules, and the splenic index and caudate lobe-right lobe ratio are useful features for differentiating alcoholic or virus-induced cirrhosis from chronic schistosomiasis using MRI.

Events can be summarized as: the hypertensive action of BK on sinusoidal cells of the periportal region is followed by its hydrolysis by ACE which is primarily present in the perivenous region; there is no functional B1R in the normal liver; BK induces HAHR via eicosanoid release and PHR by a distinct pathway on the B2R. Our data suggest that BK may participate in the modulation of sinusoidal microvasculature tonus both in the portal and the arterial routes.
