“…Therefore, one BH CSC protocol with a lower view per segment would be a more feasible approach. A previous study (9) indicated that sensitivityencoding sequences produced lower-quality diagnostic images and moderate artifact and noise than that produced by the gold standard 2D BH balanced steady-state free precession cine (8). CS could remove the artifacts in the image and improve the image quality as much as possible.…”

“…Reduced BHs and scan time would improve patients' compliance, and accelerated SA cine acquisition can be an acceptable approach. Accelerated CMR cine techniques [such as k-t blast, parallel imaging, and compressed sensing (CS)] have been used in the quantitative assessment of ventricular volume and function (8)(9)(10). Both scan time and BHs were reduced drastically when parallel imaging or CS techniques were used.…”

ObjectiveTo investigate the feasibility of 3D left ventricular global and regional strain by using one breath-hold (BH) compressed sensing cine (CSC) protocol and determine the agreement between CSC and conventional cine (CC) protocols.MethodsA total of 30 volunteers were enrolled in this study. Cardiovascular magnetic resonance (CMR) images were acquired using a 1.436 T magnetic resonance imaging (MRI) system. The CSC protocols included one BH CSC and the shortest BH CSC protocols with different parameters and were only performed in short-axis (SA) view following CC protocols. Left ventricular (LV) end-diastole volume (EDV), end-systole volume (ESV), stroke volume (SV), and ejection fraction (EF) global and regional strain were calculated by CC, one BH CSC, and shortest BH CSC protocols. The intraclass correlation coefficient (ICC) and coefficient of variance (CV) of these parameters were used to determine the agreement between different acquisitions.ResultsThe agreement of all volumetric variables and EF between the CC protocol and one BH CSC protocol was excellent (ICC > 0.9). EDV, ESV, and SV between CC and shortest BH CSC protocols also had a remarkable coherence (ICC > 0.9). The agreement of 3D LV global strain assessment between CC protocol and one BH CSC protocol was good (ICC > 0.8). Most CVs of variables were also good (CV < 15%). ICCs of all variables were lower than 0.8. CVs of all parameters were higher than 15% except global longitudinal strain (GLS) between CC and shortest BH CSC protocols. The agreement of regional strain between CC and BH CSC protocols was heterogeneous (-0.2 < ICC < 0.7). Many variables of CVs were poor.ConclusionNotably, one BH CSC protocol can be used for 3D global strain analysis, along with a good correlation with the CC protocol. The regional strain should continue to be computed by the CC protocol due to poor agreement and a remarkable variation between the protocols. The shortest BH CSC protocol was insufficient to replace the CC protocol for 3D global and regional strain.

“…Free-breathing bSSFP can be partially overcome using multiple signal averaging or respiratory gating, but usually at the expense of degraded image quality or increased scan time [5,6]. Moreover, several studies have reported signi cant differences, especially in right ventricular (RV) volumetry results obtained from the respiratory-triggered bSSFP image [7,8].…”

This study aimed to assess the image quality and accuracy of respiratory-gated real-time two-dimensional (2D) cine incorporating deep learning reconstruction (DLR) for the quanti cation of biventricular volumes and function compared with those of the standard reference, that is, breath-hold 2D balanced steady-state free precession (bSSFP) cine, in an adult population. Twenty-four patients (15 men, mean age 50.7 ± 16.5 years) underwent cardiac magnetic resonance for clinical indications, and 2D DLR and bSSFP cine were acquired on the short-axis view. The image quality scores were based on three main criteria: blood-to-myocardial contrast, endocardial edge delineation, and presence of motion artifacts throughout the cardiac cycle. Biventricular end-diastolic volume (EDV), end-systolic volume (ESV), stroke volume (SV), ejection fraction (EF), and left ventricular mass (LVM) were analyzed. The 2D DLR cine had signi cantly shorter scan time than bSSFP (41.0 ± 11.3 s vs. 327.6 ± 65.8 s; p < 0.0001). Despite an analysis of endocardial edge de nition and motion artifacts showed signi cant impairment using DLR cine compared with bSSFP (p < 0.01), the two sequences demonstrated no signi cant difference in terms of biventricular EDV, ESV, SV, and EF (p > 0.05). Moreover, the linear regression yielded good agreement between the two techniques (r ≥ 0.76). However, the LVM was underestimated for DLR cine (109.8 ± 34.6 g) compared with that for bSSFP (116.2 ± 40.2 g; p = 0.0291). Respiratory-gated 2D DLR cine is a reliable technique that could be used in the evaluation of biventricular volumes and function in an adult population.

“…Retrospectively cardiac‐gated cine balanced steady state free precession (bSSFP) images acquired during breath‐hold in short‐axis (SAx) orientation can establish high accuracy and reproducibility for functional assessment 7–10 . However, cine bSSFP imaging remains challenging for patients with limited breath‐holding capacity, as it requires multiple consecutive short breath‐holds (eg, 12 to 16 breath‐holds of 5–6 seconds each) or fewer relatively longer breath‐holds (eg, 6–8 breath‐holds of 10 to 12 seconds) 11,12 . In the case of pediatric patients with heart disease and other comorbidities, the challenges associated with breath‐holds are more pronounced due to diminished breath‐holding capacity, limited ability to cooperate, and anxiety of the closed bore environment of the MRI scanner 13 .…”

BackgroundBreath‐holding (BH) for cine balanced steady state free precession (bSSFP) imaging is challenging for patients with impaired BH capacity. Deep learning‐based reconstruction (DLR) of undersampled k‐space promises to shorten BHs while preserving image quality and accuracy of ventricular assessment.PurposeTo perform a systematic evaluation of DLR of cine bSSFP images from undersampled k‐space over a range of acceleration factors.Study TypeRetrospective.SubjectsFifteen pectus excavatum patients (mean age 16.8 ± 5.4 years, 20% female) with normal cardiac anatomy and function and 12‐second BH capability.Field Strength/Sequence1.5‐T, cine bSSFP.AssessmentRetrospective DLR was conducted by applying compressed sensitivity encoding (C‐SENSE) acceleration to systematically undersample fully sampled k‐space cine bSSFP acquisition data over an acceleration/undersampling factor (R) considering a range of 2 to 8. Quality imperceptibility (QI) measures, including structural similarity index measure, were calculated using images reconstructed from fully sampled k‐space as a reference. Image quality, including contrast and edge definition, was evaluated for diagnostic adequacy by three readers with varying levels of experience in cardiac MRI (>4 years, >18 years, and 1 year). Automated DL‐based biventricular segmentation was performed commercially available software by cardiac radiologists with more than 4 years of experience.Statistical TestsTukey box plots, linear mixed effects model, analysis of variance (ANOVA), weighted kappa, Kruskal–Wallis test, and Wilcoxon signed‐rank test were employed as appropriate. A P‐value <0.05 was considered statistically significant.ResultsThere was a significant decrease in the QI values and edge definition scores as R increased. Diagnostically adequate image quality was observed up to R = 5. The effect of R on all biventricular volumetric indices was non‐significant (P = 0.447).Data ConclusionThe biventricular volumetric indices obtained from the reconstruction of fully sampled cine bSSFP acquisitions and DLR of the same k‐space data undersampled by C‐SENSE up to R = 5 may be comparable.Evidence Level3Technical EfficacyStage 1
