Focal Myocardial Damage in Cardiac Sarcoidosis Characterized by Strain Analysis on Magnetic Resonance Tagged Imaging in Comparison with Fluorodeoxyglucose Positron Emission Tomography Accumulation and Magnetic Resonance Late Gadolinium Enhancement

Objective The aims of this study were to characterize focal myocardial damage of cardiac sarcoidosis by strain analysis and to compare it with late gadolinium enhancement (LGE) and fluorodeoxyglucose (FDG) positron emission tomography. Methods We reviewed 208 segments from 13 cardiac sarcoidosis patients and measured the circumferential strain (Ecc) and the strain change per second (Ecc rate). The mean Ecc and Ecc rate values were compared between the FDG(+) and FDG(−), and the LGE(+) and LGE(−) segments using Welch's t test. Results The peak and max Ecc rates were better in the LGE(−) segments than in the LGE(+) segments (−11.8 vs −8.9%, 40.5 vs 29.7%/s, both P
