Indications
- congenital heart disease
- aortic disease
- myocardial viabilty
- myocardial disease
- pericardial disease[1]
- quantitation of LV mass & LV function
- assessment of chronic mitral regurgitation[1]
- evaluation of coronary artery disease[5]
* late gadolinium enhancement on cardiac magnetic resonance imaging is associated with poor prognosis in myocarditis[4]
* combined assessment of inducible myocardial ischemia & late gadolinium enhancement by stress cardiac magnetic resonance imaging is useful for diagnosis & risk stratification in patients with suspected or known coronary artery disease[5]
Advantages
- high-resolution tomographic imaging & blood flow data
- quantitative right ventricular volumes & ejection fraction
- no ionizing radiation or contrast agents
- enables 3-D reconstruction of aortic & coronary artery anatomy
- gadolinium-enhanced images accurately identify viable & infarcted myocardium
- identifies anomalous coronary arteries
- outperforms myocardial perfusion & viability scintigraphy[2]
Disadvantages
- limited availability & expertise
- some patients experience claustrophobia
- may not be appropriate for patients with pacemaker, ICD, or other implanted devices
- gadolinium is contraindicated in patients with renal failure
- sinus rhythm & slower heart rate needed for image quality[1]
