From: Free-breathing 3D whole-heart coronary mra using respiratory motion-resolved sparse reconstruction

Coronary Segment 1D Respiratory Self-Navigation 4-Phase X-D GRASP (End-exp)
Left Main 1.8 ± 0.4 2.0 ± 0.0*
LAD Prox. 1.6 ± 0.5 2.0 ± 0.0*
LAD Mid 1.3 ± 0.6 1.4 ± 0.5
LAD Dist. 0.9 ± 0.5 1.3 ± 0.5
LCX Prox. 1.4 ± 0.7 1.4 ± 0.7
RCA Prox. 1.8 ± 0.4 2.0 ± 0.0
RCA Mid 1.3 ± 0.5 1.7 ± 0.5
RCA Dist. 1.4 ± 0.7 1.7 ± 0.5
Total Diagnostic Segments 41/88 (47%) 61/88 (70%)
  1. All values are expressed as mean ± one standard deviation
  2. * Indicates statistical significance compared to 1D Respiratory Self-Navigation.
  3. Diagnostic Grading: 0 = non-visible, 1 = visible but non diagnostic and 2 = visible and diagnostic
