Late
Gadolinium Enhancement (LGE) is the noninvasive gold standard for
focal fibrosis, parametric mapping with and without contrast-media
enable detection of diffuse fibrosis. We developed a non-rigid
registration method to superimpose LGE images and T1-Maps allowing
for pixel-wise comparison of LGE extent and abnormal T1 times. We
observed significantly larger regions of ECV, T1 native and
post-contrast abnormalities than LGE positive areas. However, LGE was
not always completely covered by abnormalities of any of the
mentioned parameters.
