Retrogated compressed sensing cine in one minute

Abstract Funding Acknowledgements Type of funding sources: None. PURPOSE Real-time compressed sensing cine (CSrt) provides reliable quantifications for both ventricles but impairs image quality . This aim this study was to assess the accuracy left (LV) and right ventricular (RV) volumes, ejection fraction mass based on a retrogated segmented sensing-fashioned accelerated 2D sequence (CSrg). Image also evaluated. METHOD AND MATERIALS Thirty patients were enrolled. Each patient underwent reference steady-state free precession (SSFPref), first generation real-time CSrt prototype CSrg providing same numbers positions slices. Functional parameters quantification performed SSFPref images sets. assessed three sequences by using edge sharpness which is an estimate spread function. RESULTS Mean scan times = 512 ± 15 s, 24 5 s 58 s. provided LV RV functional (end-systolic, end-diastolic, mass) not significantly different from one with (p > 0.05). Edge better (0.083 0.013 pixel-1) than (0.070 0.011 pixel-1; p 0.0004) techniques (0.075 0.016 0.0516). Inter intrarater variabilities demonstrated intraclass correlation coefficients over 0.96. CONCLUSION in minute accurate without compromising myocardial boarders impaired first-generation sequence. Figure. volumes assessment
