Talk Summary:
Molecular imaging provides quantitative, biologically specific measurements that are central to preclinical and translational research, in vivo therapy monitoring, biomarker development, and therapeutic discovery. AI methodologies are revolutionizing many areas of medical image analysis; however, effective use of AI models requires understanding of both its promise and challenges in particular applications. In molecular imaging, challenges to AI methods include smaller datasets, limited labeled data, heterogeneous acquisition protocols, and substantial domain shift across scanners, tracers, and clinical settings. This educational lecture will review data-efficient and generalizable AI approaches that can be leveraged for molecular imaging, with emphasis on segmentation of PET images and batch effects in cellular imaging. Topics will include weak supervision, semi-supervised learning, self-supervised learning, foundation models, domain adaptation and validation strategies.
