Researchers have developed a task-aware evaluation strategy for uncertainty quantification (UQ) in AI systems designed for glioma diagnosis using MRI data. The study focused on a multi-task deep learning framework that performs tumor segmentation and predicts IDH mutation status, 1p/19q co-deletion status, and tumor grade. Methods like Monte Carlo Dropout (MCD), Deep Ensembles (DE), and Monte Carlo Deep Ensembles (MCDE) were assessed for their ability to detect errors, maintain calibration, and provide interpretable uncertainty estimates across different diagnostic tasks. The findings suggest that while uncertainty estimates can aid in error detection, the effectiveness of calibration is dependent on specific parameters, and no single method consistently outperformed others across all metrics and tasks.
