Overview
Cardiac magnetic resonance imaging (CMRI) is a non-invasive test that is useful in the evaluation of overall coronary anatomy and function, and also holds a potential for plaque characterization .
Indications for CMR based on Consensus Panel report [1]
| “ |
Class I1. Assessment of global ventricular (left and right) function and mass 2. Detection of coronary artery disease
3. Acute and chronic myocardial infarction
Class II1. Detection of coronary artery disease
2. Acute and chronic myocardial infarction
Class III1. Detection of coronary artery disease
2. Acute and chronic myocardial infarction
Class Inv1. Detection of coronary artery disease
2. Acute and chronic myocardial infarction |

Note:
- Class I: provides clinically relevant information and is usually appropriate; may be used as first line imaging technique; usually supported by substantial literature.
- Class II: provides clinically relevant information and is frequently useful; other techniques may provide similar information; supported by limited literature.
- Class III: provides clinically relevant information but is infrequently used because information from other imaging techniques is usually adequate.
- Class Inv: potentially useful, but still investigational.
Detection of CAD
- Early detection of atherosclerosis and endothelial dysfunction using CMRI is possible with arterial wall imaging and assessing the reactivity of brachial artery.
- Alternative approaches include:
- Visualization of the effects of induced ischemia (wall motion, perfusion)
- Myocardial perfusion: In patients with CAD, CMR showed improvement in myocardial perfusion after coronary angioplasty [4] and in patients with cadiac syndrome X impaired sub-endocardial perfusion was observed [5].
- Direct visualization of coronary arteries (coronary angiography and flow)
