Myocardial extracellular space volume (ECV) measurement using T1 mapping in sarcoid patients. The upper row images (A-E) from a patient without cardiac involvement demonstrated a normal ECV of 25.3% and the lower row images (F-J) from a patient with cardiac involvement showed an increased ECV of 35.0%. A&F: one T1 raw image pre-contrast, B&G: one T1 raw image post-contrast, C&H: post-contrst T1 fitting curve (red line indicating blood pool and green line indicating myocardium), D&I: pre-contraset T1 map, E&J: post-contrast T1 map.
