A probabilistic deep learning approach to choroid plexus segmentation in autism spectrum disorder
The choroid plexus, a key brain barrier, can show morphological changes in autism spectrum disorder (ASD). This study introduces ASCHOPLEX, a deep learning tool for automated choroid plexus segmentation from MRI. It evaluates a probabilistic version of ASCHOPLEX, finetuned on local ASD and control datasets, and tested on the ABIDE dataset (children and adults). The tool generalized well to adults but accuracy declined in children, highlighting the need for age-specific finetuning. The probabilistic approach strengthens reliability by providing confidence metrics. Overall, ASCHOPLEX can accurately segment choroid plexus in unseen data.

Deep Learning
Deep Learning models, especially convolutional neural networks, are at the core of advanced image segmentation. ASCHOPLEX utilizes an ensemble of these models, finetuned for specific anatomical structures like the choroid plexus. The probabilistic extension, through Monte Carlo Dropout, adds a critical layer of confidence assessment, quantifying model uncertainty in its predictions, which is vital for clinical and research applications with variable data quality.

Clinical Adoption in Neuroimaging Labs
A major neuroimaging center aimed to integrate an automated choroid plexus segmentation tool into their workflow for large-scale ASD research.
Challenge: Existing methods were manual, time-consuming, subjective, and lacked generalizability across diverse patient populations, especially children.
Solution: Adopted ASCHOPLEX, finetuned it on a small local adult dataset, and leveraged its probabilistic output to assess segmentation confidence in previously unseen data, including ABIDE.
Outcome: Successfully automated segmentation with high accuracy in adult cohorts, and identified regions of higher uncertainty in pediatric data, guiding targeted manual review and highlighting the need for age-specific training data. This accelerated research throughput and improved data quality.

Your AI Implementation Roadmap
A phased approach to integrate these insights into your enterprise strategy.
Phase 01: Data Assessment & Initial Setup
Evaluate existing MRI datasets for choroid plexus visibility and quality. Set up the ASCHOPLEX environment and integrate initial training data.
Duration: 2-4 weeks
Phase 02: Finetuning & Probabilistic Model Adaptation
Conduct finetuning on a small, representative local dataset (e.g., 12 subjects) for the deterministic and probabilistic ASCHOPLEX versions. Validate finetuning performance.
Duration: 4-6 weeks
Phase 03: Large-Scale Application & Uncertainty Analysis
Apply the finetuned probabilistic model to larger unseen datasets (e.g., ABIDE). Analyze uncertainty metrics (e.g., total entropy, epistemic uncertainty) to identify areas requiring further attention or age-specific finetuning.
Duration: 6-8 weeks
Phase 04: Integration & Workflow Optimization
Integrate ASCHOPLEX into the existing neuroimaging workflow. Develop protocols for using uncertainty metrics to guide quality control and improve overall reliability.
Duration: 3-5 weeks
