Theory and Methods: A spatio-temporal regularized, groupwise, non-rigid registration method based on a B-splines deformation model and a least squares metric is used to estimate and to compensate the movement of the heart in breath-hold cine acquisitions and to obtain a quasi-static sequence with highly sparse representation in temporally transformed domains.Results: Short axis in vivo datasets are used for validation, both original multi-coil as well as DICOM data. Fully sampled data were retrospectively undersampled with various acceleration factors and reconstructions were compared with the two well-known methods k-t FOCUSS and MASTeR. The proposed method achieves higher signal to error ratio and structure similarity index for medium to high acceleration factors. Conclusions:Reconstruction methods based on groupwise registration show higher quality reconstructions for cardiac cine images than the pairwise counterparts tested.

MRI is one of the most dynamic and safe imaging techniques available in the clinic today. However, MRI acquisitions tend to be slow, limiting patient throughput and limiting potential indications for use while driving up costs. Compressed sensing (CS) is a method for accelerating MRI acquisition by acquiring less data through undersampling of k-space. This has the potential to mitigate the time-intensiveness of MRI. The limited body of research evaluating the effects of CS on MR images has been mostly positive with regards to its potential as a clinical tool. Studies have successfully accelerated MRI with this technology, with varying degrees of success. However, more must be performed before its diagnostic efficacy and benefits are clear. Studies involving a greater number radiologists and images must be completed, rating CS based on its diagnostic efficacy. Also, standardized methods for determining optimal imaging parameters must be developed.

“…7-10 Prospective ECG-triggered CS cine MRI, however, might be unable to capture the first and last phases of the cardiac cycle, because the acquisition window is set to a fixed length at the beginning of the scan. [8][9][10] This often leads to underestimation of end-dia-a prototype sequence with sparse incoherent sampling of k-space and non-linear iterative SENSE-type image reconstruction. Details regarding data acquisition and reconstruction of CS real-time cine MRI have been given in a previous report.…”

stolic volume (EDV) and, consequently, variations in stroke volume (SV) and ejection fraction (EF) relative to ECG-gated retrospective standard cine MRI. 10 To overcome this limitation, imaging data have been acquired over 2 heart beats, thus capturing the complete end-diastole between the first and second heart beats. 10 Given that CS cine MRI has the advantage of being inherently insensitive to respiratory motion because of single-shot acquisition, 11,12 it is suitable for free-breathing (FB) imaging. The purpose of this study was therefore to compare the accuracy of FB full cardiac cycle CS and BH standard cine MRI at 3.0 T for LV volume assessment in patients with cardiac conditions. Methods SubjectsThis prospective study was approved by the ethics review board of Saiseikai Matsuyama Hospital. All participants gave written consent for participation in the study. Seventy-one consecutive patients who were scheduled to R etrospective electrocardiogram (ECG)-gated cine magnetic resonance imaging (MRI) with breath hold (BH) is generally considered the standard method for assessment of left ventricular (LV) function. 1,2 This imaging sequence, however, requires multiple BH scans to cover the entire LV, thus prolonging the duration of cardiovascular MRI (CMR). In addition, many patients who undergo CMR have dyspnea, and difficulty tolerating BH. Poor BH technique can lead to poor image quality and low accuracy of LV functional assessment. Several acceleration techniques have been developed to reduce the BH duration in cine MRI. 3-5 Recently, compressed sensing (CS) with sparse sampling and iterative reconstruction was proven to reduce MRI acquisition time drastically. 6 Clinical studies have reported the utility of this technique in cine MRI for assessment of LV function with 1.5-T and 3.0-T MRI scanners. 7-10 Prospective ECG-triggered CS cine MRI, however, might be unable to capture the first and last phases of the cardiac cycle, because the acquisition window is set to a fixed length at the beginning of the scan.
