Paper doi abstract bibtex Objectives To evaluate diagnostic image quality of 3D late gadolinium enhancement (LGE) with high isotropic spatial resolution (~1.4mm3) images reconstructed from randomly under-sampled k-space using LOw-dimensional-structure Self-learning and Thresholding (LOST). Materials and Methods We prospectively enrolled 270 patients (181 men; 55±14 years) referred for myocardial viability assessment. 3D LGE with isotropic spatial resolution of 1.4±0.1 mm3 was acquired at 1.5T using LOST acceleration rate of 3 to 5. In subset of 121 patients, 3D LGE or phase-sensitive LGE were acquired with parallel imaging with acceleration rate of 2 for comparison. Two readers evaluated image quality using a scale of 1 (poor) to 4 (excellent) and assessed for scar presence. McNemar test statistic was used to compare proportion of detected scar between the two sequences. We assessed association between image quality and characteristics (age, gender, torso dimension, weight, heart rate), using generalized linear models. Overall LGE detection proportions for 3D LGE with LOST were similar between readers 1 and 2 (16.30% versus 18.15%). For image quality, readers gave 85.9% and 80.0% respectively for images categorized as good or excellent. Overall proportion of scar presence was not statistically different from conventional 3D LGE (28% vs. 33% (P= 0.17) for reader 1 and 26% vs. 31% (P= 0.37) for reader 2). Increasing subject heart rate was associated with lower image quality (estimated slope of =-0.009 (P= 0.001)). Conclusions High-resolution 3D LGE with LOST yields good to excellent image quality in \textgreater80% of patients and identifies patients with LV scar at the same rate as conventional 3D LGE.

Materials and Methods
We prospectively enrolled 270 patients (181 men; 55±14 years) referred for myocardial viability assessment. 3D LGE with isotropic spatial resolution of 1.4±0.1 mm3 was acquired at 1.5T using LOST acceleration rate of 3 to 5.

Two readers evaluated image quality using a scale of 1 (poor) to 4 (excellent) and assessed for scar presence. McNemar test statistic was used to compare proportion of detected scar between the two sequences. We assessed association between image quality and characteristics (age, gender, torso dimension, weight, heart rate), using generalized linear models. Overall LGE detection proportions for 3D LGE with LOST were similar between readers 1 and 2 (16.30\% versus 18.15\%). For image quality, readers gave 85.9\% and 80.0\% respectively for images categorized as good or excellent. Overall proportion of scar presence was not statistically different from conventional 3D LGE (28\% vs. 33\% (P= 0.17) for reader 1 and 26\% vs. 31\% (P= 0.37) for reader 2). Increasing subject heart rate was associated with lower image quality (estimated slope of =-0.009 (P= 0.001)).
Conclusions
High-resolution 3D LGE with LOST yields good to excellent image quality in {\textgreater}80\% of patients and identifies patients with LV scar at the same rate as conventional 3D LGE.},
