Fig. 8From: Native contrast visualization and tissue characterization of myocardial radiofrequency ablation and acetic acid chemoablation lesions at 0.55 TRegressions between lesion volumes measured on Day 0 in vivo and reference volumes from ex vivo measurements under ideal conditions determine whether the T1w enhancement visualized in vivo is predictive of lesion size. a Correlation of enhancing lesion volumes from in vivo T1w imaging with matching ex vivo enhancing volume indicates how well in vivo CMR can visualize lesion enhancement. b Correlation of enhancing lesion volume from in vivo T1w imaging with matching ex vivo total lesion volume demonstrates whether in vivo T1w imaging is indicative of lesion extent. c Pictorial description of thresholds used to calculate the lesion volumes from ex vivo native contrast T1w CMR. Overall, chemoablation lesions demonstrate significantly better correlationsBack to article page
