The purpose of this study was to evaluate longitudinal liver regeneration and hemodynamic changes of living donor liver transplant (LDLT) donors in response to surgical liver resection. Five living related liver donors were studied. Subjects were imaged using 4D Flow MRI before and at several times following partial hepatectomy. The ability to longitudinally evaluate liver regeneration and portal hemodynamic changes non-invasively demonstrates that 4D flow MRI is a suitable tool for both surgical planning of LDLT, and for improved understanding of the liver regeneration and hemodynamic changes that occur in the remnant liver of the donor.
