Conventional techniques require contour tracing and region of interest (ROI) placement, which may reduce reproducibility and increase analysis time. We developed a novel visual approach, the visual standardized quantification (VISTAQ) of LGE, that does not require myocardial contouring, arbitrary ROI positioning, or dedicated post-processing software.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods and results<\/jats:title>\n                    <jats:p>LGE images from 400 patients (100 prior myocardial infarction, 250 HCM, and 50 other non-ischaemic heart diseases) were analysed. Reproducibility was assessed using the intra-class correlation coefficients (ICC) and Bland\u2013Altman analysis. VISTAQ was compared with conventional methods [mean+2SD, +5SD, +6SD, full-width-at-half-maximum (FWHM), visual thresholding]. Prognostic performance was evaluated in 250 HCM patients. VISTAQ demonstrated excellent intra- and inter-observer reproducibility (ICC up to 0.98 and 0.97, respectively), consistent across disease subtypes. VISTAQ showed similar ICC to FWHM but significantly lower net and absolute inter-observer differences (median absolute difference: 1.3%). Mean+2SD markedly overestimated LGE, whereas mean+6SD slightly underestimated LGE compared with VISTAQ, mean+5SD, FWHM, and visual thresholding. Analysis time was shorter with VISTAQ (median 105 vs. 375\u2005s, P &amp;lt; 0.0001). During follow-up, 21 hard cardiac events occurred in HCM population. An LGE threshold &amp;gt;10% predicted events with higher accuracy using VISTAQ [area under the curve (AUC): 0.90; sensitivity: 85%; specificity: 94%) compared with mean+6SD (AUC: 0.75; sensitivity: 57%; specificity: 93%).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>VISTAQ provides highly reproducible, time-efficient LGE quantification without dedicated software and demonstrates non-inferior prognostic discrimination in HCM compared with conventional threshold-based techniques.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1093\/ehjimp\/qyag148","type":"journal-article","created":{"date-parts":[[2026,8,22]],"date-time":"2026-08-22T11:41:34Z","timestamp":1787398894000},"source":"Crossref","is-referenced-by-count":0,"title":["Visual standardized quantification of late gadolinium enhancement, a contour-less method for late gadolinium enhancement quantification"],"prefix":"10.1093","volume":"4","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0915-915X","authenticated-orcid":false,"given":"Giovanni Donato","family":"Aquaro","sequence":"first","affiliation":[{"name":"Department of Surgical, Medical and Molecular Pathology and of Critical Area, University of Pisa , Via Savi 10, 56126 Pisa ,","place":["Italy"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roberto","family":"Licordari","sequence":"additional","affiliation":[{"name":"Department of Clinical and Experimental Medicine, University of Messina , Messina ,","place":["Italy"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carmelo","family":"De Gori","sequence":"additional","affiliation":[{"name":"Fondazione Toscana G.
