To describe the advantage and disadvantage of gadoxetic acid (Gd-EOB-DTPA, EOB) enhanced liver MRI compared to MR images with conventional Gadolinium based MR-contrast media (Gd).
To demonstrate the various techniques for optimization for EOB enhanced MRI.
1. Basic knowledge of EOB especially focused on the aspect of hepatocellular transporter function
2. Advantage and disadvantage of EOB enhanced MRI special reference to the differences with conventional Gd-enhanced MRI for hepatobiliary examination.
3. Technical aspect of optimization for EOB-enhanced MRI
(1) EOB administration technique
(2) Take measures for acute transient dyspnea after intravenous administration of EOB
(3) Optimal flip angle for better hepatobiliary phase image acquisition
(4) Consideration of super-delayed phase image acquisition to improve conspicuity of hepatic lesions
Summary
Although EOB might be strong tool for detection and characterization of hepatic lesion, optimization of imaging protocol for EOB enhanced MRI is essential to acquire better images and improve patients’ quality of life.
