Abstract

Abstract

En 中文
• Developed DLIF, a novel deep learning framework for fully non-invasive estimation of arterial input functions in dynamic PET imaging. • Employs Vision Transformer and learned basis functions for continuous, close-form, subject-specific AIF estimation. • Demonstrated superior accuracy over traditional image-derived and decomposition-based methods, achieving state-of-the-art kinetic modeling performance. • Introduced a novel evaluation metric designed specifically for quantifying the accuracy of estimated AIFs relevant for downstream kinetic modeling analyses, such as Logan graphical analysis. • DLIF offers potential for broad clinical and research applications, significantly advancing dynamic PET neuroimaging workflows.
