Figure 4
Mean difference in Late Gadolinium Enhancement (LGE) volume (g) and % difference (%) between each semi-automated technique and expert segmentation by manual Signal Intensity (SI) threshold adjustment technique. The Signal Threshold versus Reference Mean (STRM) >3SD technique showed the greatest agreement with manual segmentation while STRM >6SD, >5SD, >4SD and full width at half maximum (FWHM) techniques systematically underestimated total enhanced volume.
