Saturday Parallel 1 Live Q&A |
Saturday, 8 August 2020, 15:30 - 16:00 UTC |
Moderators:
Liver MRI Acquisition: Michael Ohliger
Liver MRI Interpretation: Hanyu Jiang |
Skill Level: Basic to Advanced
Session Number: WE-03
Overview
Liver imaging is the most commonly used application in body MRI. High-quality liver MRI requires well-developed acquisition protocols and honed interpretive skills. This course will seek to address many of the important challenges and solutions in liver MRI acquisition and will further review basic and advanced interpretation of liver MRI.
Target Audience
Radiologists, technologists, physicists, computer scientists & trainees.
Educational Objectives
As a result of attending this course, participants should be able to:
- Summarize key features of a liver MRI examination as well as contrast agent selection;
- Describe current and emerging techniques for performing diffusion-weighted imaging in the liver, as well as methods to combat technical challenges including respiratory motion; and
- Review the interpretation of common findings in the cirrhotic and non-cirrhotic liver, as well as challenging interpretive scenarios in liver MRI.

Breathing Artifacts in Liver MRI: Emerging Solutions
Daiki Tamada
Watch the Video
Many studies have attempted to reduce motion artifacts in the liver over the years. However, it is still challenging to develop robust and practical methods to address this problem because of the complicated nature of motion artifacts. Recently, the deep learning approach has been used to achieve excellent image processing results. This talk provides an overview of deep learning-based methods to address breathing artifacts in the liver.

Liver MRI: Which Contrast Agent?
Chang-Hee Lee
Watch the Video
Extracellular agents are distributed within the extracellular interstitial space. Gadolinium chelates, which are formed by the chelation of gadolinium to organic ligands such as diethylenetriaminepentaacetic acid, constitute a class of extra-cellular agents. Although several formulations are available with different ligands, their pharmacologic characteristics and imaging considerations are essentially identical. There are multiple indications for the use of extracellular contrast agents in MR imaging of the liver. These include lesion detection, lesion characterization, and liver vasculature assessment. In this lecture, I will talk about “representative pearls and pitfalls” of the GD-EOB-DTPA Liver MRI, comparing ECA enhanced liver MRI.

Liver MRI Acquisition: Remaining Challenges
Daniel Moses Watch the Video
This educational session looks at some of the remaining challenges in respect to the technical acquisition for liver MRI. It approaches this through examining current quantitative MRI techniques (including T1/T1ρ/T2/T2* mapping, elastography, diffusion weighted imaging, perfusion weighted imaging, and proton density fat fraction) including explaining their basic principles, their clinical applicability to liver disease, and challenges in implementing these techniques.
