FIG. 6.

Epicardial lesions administered during an open-chest experiment. (a, b) Lesion core is identifiable with beige color, surrounded by a heterogeneous transition band tissue with dark red color, and a band of lighter grayish color, likely made up of CBN and edema. (c) Long-axis image from the proposed non-contrast-enhanced T1w technique shows enhanced lesion core and surrounding hypoin-tense band (arrow). LV blood is suppressed, facilitating identification of ablated tissue. (d) Contrast-enhanced image acquired on same slice. Animal was given a second dose of contrast agent and sacrificed shortly afterward. (e) Corresponding image from high-resolution ex vivo scan. (f) Volume rendering of the 3D slices gives good depiction of lesion cores and surrounding hypointense regions in anatomical context. A rotating view of this rendering is provided in Supporting Video S2.
