Researchers have developed a novel method for adapting AI models to new medical imaging modalities without extensive retraining. The study found that while simple fine-tuning methods like linear probes and fully-connected LoRA are insufficient for unseen modalities, a convolutional LoRA approach can effectively adapt models by learning transferable low-rank convolutional bases. This technique allows new modalities to be onboarded using a minimal fraction of parameters while preserving performance on existing modalities, unlike full fine-tuning which can degrade source-modality accuracy.
