DINOv2 framework unifies cardiac assessment tasks, improves LVEF estimation

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a unified framework using the DINOv2 foundation model to address three distinct cardiac assessment tasks: Left Ventricular Ejection Fraction (LVEF) estimation, global longitudinal strain (GLS)-based dysfunction classification, and early cardiotoxicity prediction. The framework employs parameter-efficient Low-Rank Adaptation (LoRA) and temporal aggregation, operating without the need for cardiac cycle segmentation or explicit End-Diastolic/End-Systolic annotations. A specialized ED/ES-guided model further enhanced LVEF estimation performance, achieving a mean absolute error of 4.64%. AI

IMPACT This research demonstrates the application of foundation models in specialized medical imaging tasks, potentially improving diagnostic accuracy and enabling earlier intervention for cardiotoxicity.
