Monitoring volumes of acute T₁-derived lesions post-ablation. a Anterior wall RF lesion visualized using IR-SSFP with lesion delineated (red lines; scale bars = 1 cm). b Cumulative volume of the T₁-derived lesions normalized to baseline (the earliest imaging time) with time after ablation. Interpolated data across 9 lesions were used to calculate mean and SE curves. All acquired data were used; the mean curve is shown only out to 184 min due to insufficient data beyond this point to create error bars
