Figure 3 Overlay Images of LA Wall Injury

Panels 1A to 1D are 4 example LA slices from the 3D DE-CMRI from Patient #1 (Fig. 1) that show close correlation of LA injury as determined by automated methods using a 3-SD cutoff value (blue transparency) overlaying MRI. Right panels show 3D overlay of full data set (3D PA and RL). LA injury mask (blue) determined by automated methods should match and overlay hyperenhanced areas (white) of true injury on DE-CMRI. Although the left pulmonary veins are white on MRI, this enhancement is attributable to navigator interference, not injured tissue, as we position the navigator over the right hemidiaphragm. The PVs are shown here only to help with anatomical orientation and are excluded from raw data used to produce injury mask by automated methods. Abbreviations as in Figures 1 and 2.
