Difficulties measuring liver blood flow have restricted our understanding of the vascular pathophysiology of liver disease and the development of therapeutic strategies to address these changes. Using phase-contrast (PC) MRI to measure portal venous flow at 9.4T, rat models of chronic liver disease have been studied using terlipressin, a clinically licensed agent for the reduction of splanchnic blood flow. Our study proceeds to demonstrate profound haemodynamic differences between animals with and without disease.
