Toward AI-Assisted Sickle Cell Screening: A Controlled Comparison of CNN, Transformer, and Hybrid Architectures Using Public Blood-Smear Images
This study benchmarks deep learning models (CNNs, Transformers, and hybrids) for AI-assisted sickle cell disease (SCD) screening using blood smear images. It emphasizes robust evaluation under data-constrained conditions, identifying MaxViT-Tiny and DenseNet121 as top performers. The findings support the use of CNN and hybrid architectures as reliable decision-support tools, with XAI suggesting CNNs focus on local morphology and hybrids integrate local and contextual cues. The research aligns with Saudi Arabia's Vision 2030 for digital health innovation.

This category focuses on the application of artificial intelligence, particularly deep learning, to medical image analysis. It encompasses tasks like disease detection, diagnosis, and prognosis using various imaging modalities such as blood smears, radiography, MRI, and CT scans. Key challenges include robust performance under data limitations, interpretability, and clinical validation.
MaxViT-Tiny and DenseNet121 Lead in Robustness
93.5%Mean Accuracy (±SD) Across Repeated Splits
The hybrid MaxViT-Tiny model achieved the highest mean test accuracy of 93.5% (±0.026), closely followed by DenseNet121 at 93.3% (±0.021). These models demonstrated superior stability and performance under data-constrained conditions, highlighting the importance of convolutional inductive bias for morphology-driven tasks.
Controlled Evaluation Methodology
Our rigorous evaluation protocol ensured fair comparison by controlling for data leakage, augmentation, and training conditions. This allowed for an isolated assessment of architectural inductive biases.

Addressing False Positives in SCD Screening
Error analysis revealed a dominance of false-positive predictions across all top models. This reflects a conservative classification tendency, prioritizing sensitivity over specificity—a desirable trait in initial screening where missing a true positive is more critical. Factors contributing to false positives include overlapping cells, staining artifacts, and borderline morphological variations that resemble sickling. MaxViT-Tiny, with its hybrid design, effectively integrates local and global cues, demonstrating robust performance even in ambiguous cases by leveraging its combined feature extraction capabilities.
XAI Reveals Distinct Model Focus
Local vs. GlobalFeature Attention Patterns
Explainable AI (XAI) visualizations show that CNNs (e.g., DenseNet121) focus on localized red blood cell morphology, while hybrid models (MaxViT-Tiny) integrate both local cellular features and broader contextual information. This suggests that CNNs excel at morphology-driven tasks due to their inductive bias, while hybrids benefit from a broader understanding of the image context.
