Overview
Currently, cardiac MRI(CMR) is the technique of choice in diagnosis of subclinical or clinical cardiac sarcoidosis. It is fast, accurate, and noninvasive.
MRI
Currently, cardiac MRI and/or PET scanning is proposed to be most specific for diagnosis of cardiac sarcoidosis[1]. T1-weighted MR shows :
- wall motion abnormalities
- Hypertrophy due to infiltration
- Wall thinning
- Heart failure
- Late gadolinium enhancement (delayed enhancement) evaluates scar/fibrosis and can differentiate chronic versus active disease. Some studies also suggest that monitoring gadolinium enhancement may be helpful in the assessment of response to treatment with steroids[2][3][4].
