Diffusion MRI denoising put to the test: Researchers assess image sharpness effects on glaucoma detection

For decades, MRI (magnetic resonance imaging) has been a powerful way to see inside the human brain. A specialized form, diffusion-weighted MRI (dMRI), can measure tissue properties of fiber pathways ...

Does a sharper image lead to better results? Diffusion MRI denoising put to the test

Left: Study design. We analyzed dMRI data acquired from 17 patients with glaucoma and 30 healthy controls, and then compared the data with and without denoising. Right: Comparison between data with ...

Transformer-guided denoising diffusion probabilistic model (DDPM) for flow field super-resolution (IMAGE)

A novel FlowViT-Diff framework that integrates a Vision Transformer (ViT) with an enhanced denoising diffusion probabilistic model (DDPM) for super-resolution reconstruction of high-resolution flow ...
