...Conceptually, without a mandate for breath holding or even sinus rhythm, free-breathing CMR scanning may be (1) less taxing to the patient and technologist who otherwise must coordinate their efforts; (2) more efficient, given the absence of delays between breath holds or repeated acquisitions, which are pronounced with frail patients; (3) more robust diagnostically, yielding high image quality with higher signal-to-noise ratios (SNRs; averaging) and freedom from ghosting artifacts (common in breath-held [bh] acquisitions);(1) and (4) more consistent and generalizable, extending these capabilities to more vulnerable patients with dyspnea, arrhythmia, and other comorbidity who can be challenging to image....

...We examined separate blinded image analyses to compare mocoLGE and bh-LGE on the basis of (1) pixelwise infarct size measures, (2) acquisition time, (3) image quality scores, (4) image confidence scores, and (5) ability to stratify risk of subsequent outcomes in the full cohort of consecutive patients....

...In particular, several solutions have been introduced in the case of dynamic contrast enhanced (DCE) data with non-rigid deformations and with specific considerations made for the changes in intensity (Melbourne et al 2011, Filipovic et al 2011, Wollny et al 2012)....
