Researchers have developed TRACE, a concept bottleneck model designed for interpretable longitudinal glioblastoma response assessment using 3D MRI scans. Unlike traditional deep learning methods that directly predict labels, TRACE utilizes clinically meaningful tumor measurements as root concepts and derives downstream concepts through deterministic rules, aligning with RANO 2.0 criteria. The model processes paired baseline and follow-up scans, incorporating scan intervals and new lesion information. In cross-validation on the LUMIERE dataset, TRACE achieved a 4-class macro F1 of 0.4769 and a binary F1 of 0.7085, demonstrating performance comparable to non-interpretable deep learning approaches and improving upon a concept bottleneck baseline.
