How to do CMR 1

Basic course

Non-Invasive Imaging


The first session of the basic course focused on CMR physics, cardiac function, cardiac deformation, flow imaging, valve imaging and angiography.
Dr Boubertakh opened the session reminding the principles of CMR physics, standard MRI components, MRI basics, and how different magnetic resonance signals can be acquired.
Dr Piechnik described the sequences used in clinical practice, interestingly comparing these sequences to building blocks. The design of CMR sequences is well established. Therefore, future improvement will mainly rely on advances in hardware, software, and reconstruction techniques.
Dr Greenwood commented on CMR imaging at 3 Tesla. Higher magnetic field strengths have the potential to improve image quality, resolution and acquisition times, and appear particularly useful for angiography and perfusion. The caveats of high field imaging were discussed, as well as potential solutions to overcome these limitations.
Dr Almeida reminded us on how to do biventricular function. CMR is considered the standard for evaluating ventricular volumes, ejection fraction and mass. Several approaches were discussed for optimal measurements.
Dr Kilner reviewed how to do myocardial deformation (tagging, encoding and feature tracking approaches). Several interesting examples were presented, but routine application of these advanced techniques is still to be seen.
Dr Alpendurada looked at the principles of flow and valve imaging. CMR is established in the evaluation and quantification of shunts and valve disease. Several parameters were discussed in order to optimize image acquisition and analysis.
Dr Gutberlet talked on how to do angiography and coronary imaging, giving useful tips for optimal image results. Whilst the evaluation of the aorta and other great vessels is well documented, the assessment of coronary arteries, particular coronary stenosis, is still limited.
