Imaging was anonymized for blinded analysis of (1) LGE images, and (2) a 3D fusion image with LGE projected onto a segmented LA surface. Scans were categorized using both assessment techniques separately as pre\u2010 or postablation, and if postablation, whether lesions were in an ostial or WACA distribution.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>\n                      <jats:italic>Results:<\/jats:italic>\n                    <\/jats:bold>\n                    LGE imaging was performed in 50 patients (aged 60 \u00b1 10 years, 68% male, 24 underwent WACA and 26 had cryoablation). Sensitivity and specificity for detection of ablation lesions was 60% and 96% on LGE imaging. Sensitivity was higher using 3D fusion imaging (88%; P = 0.003). The proportion in whom lesions were both detected and the distribution correctly assessed as WACA or ostial was higher with 3D fusion imaging compared to LGE imaging (54% vs 28%; P = 0.014). There was no difference in the detection of radiofrequency ablation lesions compared to cryoablation lesions (58% vs 62%; P = 1.000).\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>\n                      <jats:italic>Conclusion:<\/jats:italic>\n                    <\/jats:bold>\n                    LGE imaging of atrial scar is not yet sufficiently accurate to reliably identify ablation lesions or to determine lesion distribution.\n                    <jats:italic>(J Cardiovasc Electrophysiol, Vol. 24, pp. 396\u2010403, April 2013)<\/jats:italic>\n                  <\/jats:p>","DOI":"10.1111\/jce.12063","type":"journal-article","created":{"date-parts":[[2012,11,28]],"date-time":"2012-11-28T19:25:45Z","timestamp":1354130745000},"page":"396-403","source":"Crossref","is-referenced-by-count":58,"title":["Diagnostic Accuracy of Cardiac Magnetic Resonance Imaging in the Detection and Characterization of Left Atrial Catheter Ablation Lesions: A Multicenter Experience"],"prefix":"10.1111","volume":"24","author":[{"given":"ROSS J.","family":"HUNTER","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"DANIEL A.","family":"JONES","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"REDHA","family":"BOUBERTAKH","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"LOUISA C.","family":"MALCOLME\u2010LAWES","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"PRAPA","family":"KANAGARATNAM","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"CHRISTOPH F.","family":"JULI","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D.
