Fig. 1

Representative examples of T1 mapping with corresponding LGE images. The color bars of all T1 maps are exhibited on the lower left quarter of the top row of figures. Changes in color from the bottom to the top of the color bar correspond to value increases. Top row: An ESRD patient suffering from HF had a longer native T1 value (1412.72 ms) (a) and a shorter post-contrast T1 value (411.92 ms) (b) with increasing ECV (33.61%) and a redder ECV map (c) and diffuse LGE (d). Middle row: An ESRD patient without HF showing a lower native T1 value, post T1 value (f) and ECV exhibited a patchy LGE (h) and a corresponding patchy native T1 (e) and ECV (g) enlargement area (patchy deep red area in the ECV map) in T1 mapping (white arrow). Bottom row: Native T1, post-contrast T1 and ECV mapping were homogeneous in a normal control subject (1189 ms, 518.33 ms, 24.33%) (i-l) without LGE enhancement. LGE, late gadolinium enhancement; ESRD, end-stage renal disease; HF, heart failure; ECV, extracellular volume
