Impact of Synthetic Lesional MR Images in Automated Focal Cortical Dysplasia Detection in Low-Data Scenarios
arXiv:2606.07381v1 Announce Type: cross Abstract: Background and Purpose: Automated detection of focal cortical dysplasia (FCD) requires large volumes of voxelwise lesion-delineated MRI data, which are difficult to acquire. This study aims to generate synthetic MRI data exhibiting FCD, assess their realism, and evaluate their impact on automated FCD detection, particularly in reducing the need for manual annotations. Methods: T1-weighted (T1w) and T2-weighted Fluid-Attenuated Inversion Recovery (FLAIR) MRI scans from 131 FCD patients and 90 healthy controls from multiple (3) sites were retrosp
The rapid advancement in generative AI models, particularly for image synthesis, enables the creation of high-fidelity synthetic medical data, addressing persistent data scarcity in specialized fields.
This development significantly enhances the accessibility and accuracy of AI-driven medical diagnostics, especially for rare conditions where real-world data collection is challenging and expensive.
The reliance on vast, manually-annotated real-world medical datasets for training diagnostic AI models is reduced, accelerating the deployment and improving the performance of these systems.

- · Patients with rare diseases
- · Hospitals with limited data acquisition resources
- · Generative AI model providers
- · Traditional manual medical image annotation services
- · Diagnostic methods heavily reliant on human interpretation of complex imaging
- · Research institutions without access to advanced synthetic data generation tools
Automated FCD detection systems become more accurate and widely deployable, improving early diagnosis.
Reduced diagnostic delays for neurological conditions lead to earlier intervention and potentially better patient outcomes, while also lowering healthcare costs associated with late diagnosis.
The methodology for synthetic data generation becomes a standard practice in developing AI for various medical specialties, democratizing access to powerful diagnostic tools globally.
