Article Snippet: With conventional ECG gating and array coils at 1.5 T (Magnetom Aera and Magnetom Avanto fit Siemens Healthineers), the conventional SSFP SAX cine stack was acquired as for standard clinical CMR as widely described in the literature and using GRAPPA with 46 reference lines acquired during each BH [ , ].

Figure Lengend Snippet: The ECG, LV volume, and cine slice positions plotted against time, showing the difference between previous real-time CS cine stack methods and the new single-cycle stack-advance method. Please note that this figure does not depict the gold-standard conventional cine applied in this work. Blue bars show cine data acquisition, and orange bars show prior SSFP stabilization of the slice. Data acquisition is inevitably slightly delayed by half the frame time after R-wave detection. ( a ) In the previous method for real-time CS for single breath-hold cine stack acquisition to capture an entire cardiac cycle, most of the following cycle is typically spent stabilizing and waiting for the next R-wave. This method was not run in this work. ( b ) The faster method evaluated in this work against conventional BH “segmented k-space” cine imaging. This modification omits late-diastolic acquisition, enabling single-cycle stack-advance (SCSA) to acquire the same number of SAX slices in half the breath-hold time. SCSA has shortened SSFP stabilization time of each slice compared to the previous real-time cine SSFP method All cines in this work were 8 mm thick with 2-mm gaps. CS, compressed sense; SCSA, single-cycle stack-advance; SSFP, steady-state free precession

Figure Lengend Snippet: Effect of motion correction on CRC and CNR. The top plot shows the changes in contrast recovery when motion compensation is fully performed ( DUAL , as in dual-gated studies), or only ECG gating is performed ( ECG , one cardiac gate blurred by the respiratory motion) or if ECG gating is performed starting from a dataset where the respiratory motion has been compensated ( ECG+R , one cardiac gate, less noisy)

Article Snippet: If the respiratory motion correction is neglected and only ECG gating is performed on the original list-mode dataset ( ECG bars in the Figure), the lesions are hardly distinguishable due to the motion blur.
