Convolutional neural network‐aided tuber segmentation in tuberous sclerosis complex patients correlates with electroencephalogram

Abstract: Objective: One of the clinical hallmarks of tuberous sclerosis complex (TSC) is radiologically identified cortical tubers, which are present in most patients.Intractable epilepsy may require surgery, often involving invasive diagnostic procedures such as intracranial electroencephalography (EEG). Identifying the location of the dominant tuber responsible for generating epileptic activities is a critical issue. However, the link between cortical tubers and epileptogenesis is poorly understood. Given this, we hy… Show more

“…The study participants were epilepsy patients seeking treatment at the Epilepsy Center, Beijing Fengtai Hospital and Beijing Tiantan Hospital between January 2015 and December 2020. Subjects included in the study met the diagnostic criteria of TSC according to the International TSC Consensus Group in 2012 (Supplemental Material Content S1) [14]. Four classic central nervous system findings are associated with TSC: cortical and subcortical tubers, cerebral white matter heterotopia, subependymal nodules (SENs), and subependymal giant cell astrocytoma (SEGAs) [15].…”

“…The epileptogenic tubers were unambiguously defined only if the patient received surgery and remained seizure-free in the last follow-up [14]. Unfortunately, surgical resection and resultant data on seizure freedom were unavailable for some of our patients.…”

“…Previously, deep learning models and multi-contrast MRIs have been successfully used for automatically detecting strokes [15] and classifying brain tissues [16]. Until now, convolutional neural networks (CNNs) have been applied to assist in tuber segmentation in TSC patients [17]. Sanchez et al [18] used two types of contrast MRI, T2W and FLAIR, for the detection task of TSC tubers and achieved the receiver operating characteristic curve that can have an area under the curve (AUC) of 0.99.…”
