Supplement: Multicenter validated detection of focal cortical dysplasia using deep learning
<p><span><b><span>Objective</span></b><span>. </span><span><span>To test the hypothesis that a multicenter-validated computer deep learning algorithm detects MRI-negative focal cortical dysplasia (FCD).</span></span></span></p> <p><span><b><span>Methods</span></b><span>. We used clinically acquired 3D T1-weighted and 3D FLAIR MRI of 148 patients (median age, 23 years [range, 2-55]; 47% female) with histologically verified FCD at nine centers to train a deep convolutional neural network (CNN) classifier. Images were initially deemed as MRI-negative in 51% of cases, in whom intracranial EEG determined the focus. For risk stratification, the CNN incorporated Bayesian uncertainty estimation as a measure of confidence. To evaluate performance, detection maps were compared to expert FCD manual labels. </span><span><span>We also tested sensitivity in an independent cohort of </span></span><span><span>23 FCD cases (13±10 years</span></span><span><span>).</span></span><span> Applying the algorithm to 38 healthy and 63 temporal lobe epilepsy disease controls tested specificity. </span></span></p> <p><span><b><span>Results.</span></b><span> Overall sensitivity was 93% (137/148 FCD detected) using a leave-one-site-out cross-validation, with an average of six false positives per patient. Sensitivity in MRI-negative FCD was 85%. In 73% of patients, the FCD was among the clusters with the highest confidence; in half it ranked the highest. </span><span><span>Sensitivity in the </span></span><span><span>independent cohort was </span></span><span><span>83% (19/23; average of five false positives per patient).</span></span><span> Specificity was 89% in healthy and disease controls.</span></span></p> <p><span><b><span>Conclusions</span></b><span>. This first multicenter-validated deep learning detection algorithm yields the highest sensitivity to date in MRI-negative FCD. By pairing predictions with risk stratification</span><span><span> this classifier may assist clinicians to adjust hypotheses relative to other tests, increasing </span></span><span>diagnostic confidence</span><span><span>.</span></span><span> Moreover, generalizability across age and MRI hardware </span><span><span>makes this approach ideal for pre-surgical evaluation of MRI-negative epilepsy. </span></span></span></p> <p><b><span>Classification of evidence</span></b><span>. This study provides Class III evidence that deep learning on multimodal MRI accurately identifies FCD in epilepsy patients initially diagnosed as MRI-negative.</span></p>
