Artefacts in Cardiovascular MR - ISMRM 24th Annual Meeting & Exhibition

ISMRM 24th Annual Meeting & Exhibition • 07-13 May 2016 • Singapore

Sunrise Educational Session: Artefacts in Cardiovascular MR

Skill Level: Intermediate to Advanced

Organizers: Thomas K. F. Foo, Ph.D. & Harald Kramer, M.D.

Thursday 12 May 2016

Overview
This session will appraise the audience of some of the specific artifacts that are encountered in clinical cardiovascular imaging. The speakers will describe the appearance of the artefacts, explain their physical origin and, where possible, recommend methods to mitigate their appearance.

Target Audience
Scientists, engineers and clinicians who wish to recognise and explain the various artifacts that can be encountered in clinical cardiovascular imaging.

Educational Objectives
Upon completion of this course, participants should be able to:

Recognise typical artifacts encountered in clinical cardiovascular MRI;
Explain the underlying physical principles that cause the artifact; and
Describe methods that can be used to avoid or diminish artifacts.

PROGRAM

Moderators: Thomas Foo, Michael Ingrisch

07:00	Artifacts in CMR Pedro Ferreira¹ ¹Cardiovascular BRU, Royal Brompton Hospital, London, United Kingdom Cardiovascular imaging is complicated primarily by the complex nature of the cardiac motion. Many of the cardiac imaging artifacts are directly related to motion or indirectly introduced by the requirement to shorten the acquisition time to remove motion. The complex cardiac structure with mixtures of fat and water based tissues containing complex and varying blood flows, and the large chest region with many organs and tissue-air interfaces also open the door to additional artifacts and measurement errors. Common cardiovascular MR artifacts are presented with a short description of the mechanisms behind them, and possible solutions and trade-offs.
07:25	Artifacts in MRA Stanislas Rapacchi¹ ¹Aix-Marseille Université This course targets scientists and clinicians interested in MR Angiography (MRA). We will seek to offer a comprehensive overview of the limitations of MRA and the technical solutions implemented throughout little "guess-the-artifact" games. We will go thought the identification of spurious artifacts in MRA so that the audience can understand the underlying sources of artifacts and the consequent proposals to mitigate their manifestations. There is no requirement for this course, but a minimum knowledge in MRA basic principles is preferable. At the end of this presentation, participants should appreciate how MR-Angiography stands nowadays as a robust and precise mean for the assessment of cardiovascular pathologies and should be able to discuss the pros and cons of CE and NCE MRA in terms of artifacts.
