DWI SNR Q&A: Key Concepts for Optimizing Diffusion-Weighted Imaging

MRI Questions' new educational post clarifies diffusion-weighted imaging signal-to-noise ratio (SNR) fundamentals, including factors that degrade SNR and sequence adjustments that can improve image quality.

• Covers DWI physics, SNR determinants (b-value, TE, voxel size), and common artifacts.
• Aimed at radiology residents, technologists, and practicing radiologists for board review and protocol optimization.
