AB  - OBJECTIVE: To qualitatively and quantitatively compare different late gadolinium 
      enhancement (LGE) sequences acquired at 3T with a parallel RF transmission 
      technique. METHODS: One hundred and sixty participants prospectively enrolled 
      underwent a 3T cardiac MRI with 3 different LGE sequences: 3D Phase-Sensitive 
      Inversion-Recovery (3D-PSIR) acquired 5 minutes after injection, 3D 
      Inversion-Recovery (3D-IR) at 9 minutes and 3D-PSIR at 13 minutes. All 
      LGE-positive patients were qualitatively evaluated both independently and blindly 
      by two radiologists using a 4-level scale, and quantitatively assessed with 
      measurement of contrast-to-noise ratio and LGE maximal surface. Statistical 
      analyses were calculated under a Bayesian paradigm using MCMC methods. RESULTS: 
      Fifty patients (70 % men, 56yo +/- 19) exhibited LGE (62 % were post-ischemic, 30 % 
      related to cardiomyopathy and 8 % post-myocarditis). Early and late 3D-PSIR were 
      superior to 3D-IR sequences (global quality, estimated coefficient 
      IR > early-PSIR : -2.37 CI = [-3.46 ; -1.38], prob(coef > 0) = 0 % and 
      late-PSIR > IR : 3.12 CI = [0.62 ; 4.41], prob(coef > 0) = 100 %), LGE surface 
      estimated coefficient IR > early-PSIR: -0.09 CI = [-1.11; -0.74], 
      prob(coef > 0) = 0 % and late-PSIR > IR : 0.96 CI = [0.77; 1.15], 
      prob(coef > 0) = 100 %). Probabilities for late PSIR being superior to early PSIR 
      concerning global quality and CNR were over 90 %, regardless of the aetiological 
      subgroup. CONCLUSIONS: In 3T cardiac MRI acquired with parallel RF transmission 
      technique, 3D-PSIR is qualitatively and quantitatively superior to 3D-IR. KEY 
      POINTS: * Late gadolinium enhancement is an essential part of a cardiac MRI 
      examination * PSIR and IR sequences are the two possible options for LGE imaging 
      * At 3T with parallel RF transmission, PSIR sequences are significantly better * 
      One LGE sequence is sufficient, allowing an optimization of the acquisition time.
