Hypometabolic characteristics have been extensively examined in prior studies, but the metabolic patterns associated with specific pathological types of drug\u2010resistant epilepsy remain to be fully defined. This study was developed to explore the relationship between metabolic patterns or characteristics and surgical outcomes in type I and II focal cortical dysplasia (FCD) patients based on results from a large cohort.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Data from individuals who underwent epilepsy surgery from 2014 to 2019 with a follow\u2010up duration of over 3\u2009years and a pathological classification of type I or II FCD in our hospital were retrospectively analyzed. Hypometabolic patterns were quantitatively identified via statistical parametric mapping (SPM) and qualitatively analyzed via visual examination of PET\u2010MRI co\u2010registration images. Univariate analyses were used to explore the relationship between metabolic patterns and surgical outcomes.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>In total, this study included data from 210 patients. Following SPM calculations, four hypometabolic patterns were defined including unilobar, multi\u2010lobar, and remote patterns as well as cases where no pattern was evident. In type II FCD patients, the unilobar pattern was associated with the best surgical outcomes (<jats:italic>p<\/jats:italic>\u2009=\u20090.014). In visual analysis, single gyrus (<jats:italic>p<\/jats:italic>\u2009=\u20090.032) and Clear\u2010cut hypometabolism edge (<jats:italic>p<\/jats:italic>\u2009=\u20090.040) patterns exhibited better surgery outcomes in the type II FCD group.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>PET metabolic patterns are well\u2010correlated with the prognosis of type II FCD patients.
