ISMRM 24th Annual Meeting & Exhibition • 07-13 May 2016 • Singapore |
Sunrise Educational Session: Cardiovascular Image Processing
Skill Level: Intermediate to Advanced
Organizers: Daniel Ennis, Ph.D. & Martin J. Graves, Ph.D.
Wednesday 11 May 2016 |
Overview
This session will describe the various image processing methods used to extract quantitative information from cardiac MRI images. The speakers will explain the approaches used for the analysis and display of global and regional ventricular function, the requirements for quantitative analysis of myocardial perfusion images and the methods used to extract quantitative data from phase contrast techniques.
Target Audience
Scientists, engineers and clinicians with a good understanding of cardiovascular MRI who wish to understand the image processing algorithms and methods used for the quantitative analysis of functional cardiac images, myocardial perfusion studies and 2D and 4D phase contrast data.
Educational Objectives
Upon completion of this course, participants should be able to:
- Describe the methods used for the quantitative analysis of ventricular function;
- Assess the algorithms used for the quantification of myocardial perfusion; and
- Discuss the techniques used for quantification of flow from 2D and 4D phase contrast methods.

Functional Analysis
Daniel Ennis1 and

Netherlands
Assessment of LV dimensions and global systolic function
is a key element of every CMR examination. Accurate and
reproducible quantification is highly important and
requires an appropriate MR acquisition protocol as well
as careful use of image analysis methods.

Perfusion Quantification
Michael Jerosch-Herold1

Boston, MA, United States
This presentation focuses on the quantification of
myocardial perfusion using rapid dynamic imaging during
the first pass of contrast bolus through the heart. The
approaches which can be used for quantifying myocardial
blood flow from the observed contrast enhancement can be
broadly divided into two categories, which we label here
as model-based and model-independent. For model-based
approaches one specifies the functional spaces in
myocardial tissue, how tracer moves through these
spaces, and how it traverses permeable barriers between
the spaces. Model-independent analysis means that one
foregoes specifying a model of the tissue structure.
Model-independent analysis is based on the central
volume principle.

2D/4D Flow Quantification
Alejandro Roldan-Alzate
This presentation will review the data acquisition, post
processing, and blood flow quantification using standard
2D PC and 4D Flow MRI. Sources of error for the blood
flow measurements will also be analyzed.
