JCMR 2021; 23:57. Clinical comparison of sub-mm high-resolution non-contrast coronary CMR angiography against coronary CT angiography in patients with low-intermediate risk of coronary artery disease: a single center trial (CME)


The anatomical assessment of coronary artery disease is clinically performed with either invasive X-ray coronary angiography or coronary computed coronary angiography (CCTA). However, limitations include invasive complications, iodine based contrast agents and ionising radiation. Coronary magnetic resonance angiography (CMRA) is a potential safe alternative which could be performed with or without gadolinium contrast agents. Despite this, conventional CMRA is limited by low scan efficiency, long and unpredictable acquisition times, low spatial resolution and image quality degradation due to cardiac, respiratory and patient motion artefacts. This activity describes and clinically validates a novel CMRA framework, which has a sub-1mm spatial resolution, 100% respiratory scan efficiency, and incorporates highly advanced 3D rigid and non-rigid motion estimation frameworks which can be obtained in a predictable acquisition time of approximately 10 minutes.


This CME activity is designed to enhance the learner understanding of a recently developed, high spatial resolution coronary magnetic resonance angiography sequence, which has been validated in a cohort of patients with low-intermediate risk of coronary artery disease.


Learning Objective

To close the gap outlined above:

1. Learners need to know about: Coronary magnetic resonance angiography, coronary artery disease, respiratory motion correction techniques, highly under sampled acquisition and reconstruction techniques.

2. Learners need to know how to apply: Coronary artery assessment, coronary magnetic resonance angiography described in this topic.

3. Learners need to perform: Further reading around the topic of advanced coronary magnetic resonance angiography.
