Deep learning-based enhancement of ultra-low-dose multi-tracer PET/MR: a technical feasibility study in Alzheimer’s disease
To develop a Dual-Branch Dense Wavelet Attention Network (DDWAN) for enhancing simulated ultra-low-dose multi-tracer (Aβ, tau and FDG) PET imaging acquired on a PET/MR system and to evaluate its technical feasibility in Alzheimer’s disease (AD), using full-dose images acquired under the same protocol as reference...
