Overview
There are no MRI findings associated with the spontaneous coronary artery dissection. Magnetic resonance angiography may be useful in the detection of aneurysms. However, MRA is associated with long scanning time and it may also have false negative or positive results.
MRI
- Cardiac magnetic resonance (CMR) is a valuable tool for diagnosis of spontaneose coronary artery dissection (SCAD) in patients as follows:
- Pregnant women for avoiding radiation of coronary angiography
- Unclear evidence of acute coronary syndrome during coronary angiography
- Differentiating of SCAD from myocarditis, tukotsobo cardiomyopathy
- Evidence of myocardial infarction with subendocardial LGE
- Microvascular obstruction
- Myocardial edema
MRA
- Magnetic resonance angiography may be useful in the detection of aneurysms. However, MRA is associated with long scanning time and it may also have false negative or positive results.
