Representative contrast agent first pass T₂^* imagings with a photomicrograph of TTC-stained tissue.

<p>The extent of T₂^* signal hypoenhancement caused by entry of Gd-DTPA and P792 in scarred myocardium were comparable to those in normal myocardium. There were no differences in T₂^* signal loss between scarred and normal myocardium at wash-in and peak T₂^* imaging. Upper panel: T₂^* imaging during the first pass of Gd-DTPA; Lower panel: T₂^* imaging during the first pass of P792; First vertical line: precontrast T₂^* imaging; Second vertical line: wash-in T₂^* imaging; Third vertical line: peak T₂^* imaging; Fourth vertical line: TTC stained section.
