Motivation: Liver donor evaluation requires high-quality imaging to evaluate vascular and biliary anatomy, and is traditionally performed using multiple modalities,which can be challenging for both patients and physicians.
Goal(s): Explore the use of dual-contrast agent MRCP to better define donor anatomy as an alternative to the combined use of CTA and single-contrast MRCP.
Approach: Dual-contrast MRCP was performed using gadobenate dimeglumine for dynamic arterial-phase imaging, followed by gadoxetate disodium for biliary imaging.
Results: From November 2022 to October 2024, 52 potential donors were scanned, 7 underwent partial hepatectomy, only one of which required additional CTA to verify complex arterial anatomy. None had postoperative complications.
Impact: Dual-contrast agent MRI and MRCP can be used as a one-stop shop for high-quality arterial and biliary imaging of living liver donors, reducing radiation exposure, cost and time constraints.
