Patient infarct quantification. Agreement between 2D-PSIR and 3D-IR in absolute infarct volume in patients. (A) 2D-PSIR versus 3D-IR (r = 0.97) and the line of identity (B) The limits of agreement between the two LGE-techniques. The difference between the two methods was 0.47 ± 2.1 ml scar. Solid line = mean difference; dashed lines = ± 2 SD.
