Portal hypertension (PHTN) creates complex flow
dynamics. Treatments aim to reduce the morbidity by
reducing the portosystemic gradient and/or treating
varices. Treatments have variable success depending on
flow dynamics in the portal venous system. We
successfully imaged normal patients, patients with PHTN
and patients after placement of TIPS with volumetric
phase contrast free breathing technique. The results
were compared with invasive wedge and free hepatic vein
pressures and Doppler ultrasound. In the future,
volumetric phase contrast MRI may provide reproducible
user-independent velocity and flow quantification
information in a patients with PHTN assisting in both
pre-procedure planning and post-procedure follow-up.
