Figure 2

Example of ex-vivo cardiac T2* scans.

Representative images of two hearts are shown at increasing echo times (TE) from 3ms to 17.4ms. Heart 1 has normal iron levels and remains bright whereas heart 2 (which has severe iron loading) shows progressive darkening with increasing echo time. The graph shows signal intensity (arbitrary units) plotted against echo time (ms) for the hearts in upper panel. Heart 1 has a shallow decay curve with T2* value of >20ms. Heart 2 has a much more rapid decay with T2* <10ms.
