“…For depicting the heterogeneous infarct zone with branches in the middle of the septum indicated by the arrow heads, the result from CP‐LASER matches the best with the corresponding features on the fully sampled 3D MCLE images in Figure a and the histopathology image in Figure d; the 2D LGE image with a slice thickness of 5 mm in Figure c underestimates this region due to partial volume effects. In the signal intensity profiles in Figure a and b, CP‐LASER yields fine features in the infarct‐myocardium border zones closer to those from the fully sampled data than either CS‐LASER or L1‐ESPIRiT with LLR, as indicated by the black arrows. To further explain the artifacts presented by CS‐LASER in tissue border areas, http://binarystore.wiley.com/store/10.1002/mrm.26970/asset/supinfo/mrm26970-sup-0001-suppinfo01.pdf?v=1&s=39a00524ebadab059840e6d1779a3bd0dd89eaa4 shows 3D MCLE images associated with individual coils reconstructed from CS‐LASER at the inversion time of 75 ms for the same slice.…”

“…There is growing evidence that characteristics of the peri‐infarct border zone (or gray zone), delineated by cardiac magnetic resonance (CMR), have the potential to inform the management of ventricular tachycardia (VT) in patients with prior myocardial infarction (MI) . The critical isthmuses of VTs have been located in the peri‐infarct border zone identified using CMR on patients with prior MI .…”

Isotropic three-dimensional (3D) acquisition is a challenging task in magnetic resonance imaging (MRI). Particularly in cardiac MRI, due to hardware and time limitations, current 3D acquisitions are limited by low-resolution, especially in the through-plane direction, leading to poor image quality in that dimension. To overcome this problem, super-resolution (SR) techniques have been proposed to reconstruct a single isotropic 3D volume from multiple anisotropic acquisitions. Previously, local regularization techniques such as total variation have been applied to limit noise amplification while preserving sharp edges and small features in the images. In this paper, inspired by the recent progress in patch-based reconstruction, we propose a novel isotropic 3D reconstruction scheme that integrates non-local and self-similarity information from 3D patch neighborhoods. By grouping 3D patches with similar structures, we enforce the natural sparsity of MR images, which can be expressed by a low-rank structure, leading to robust image reconstruction with high signal-to-noise ratio efficiency. An Augmented Lagrangian formulation of the problem is proposed to efficiently decompose the optimization into a low-rank volume denoising and a SR reconstruction. Experimental results in simulations, brain imaging and clinical cardiac MRI, demonstrate that the proposed joint SR and self-similarity learning framework outperforms current state-of-the-art methods. The proposed reconstruction of isotropic 3D volumes may be particularly useful for cardiac applications, such as myocardial infarction scar assessment by late gadolinium enhancement MRI.
