Phase-correcting non-local means filtering for diffusion-weighted imaging of the spinal cord

Kafalı, Sevgi Gökçe; Çukur, Tolga; Sarıtaş, Emine Ülkü (John Wiley, 2018)

Purpose: DWI suffers from low SNR when compared to anatomical MRI. To maintain reasonable SNR at relatively high spatial resolution, multiple acquisitions must be averaged. However, subject motion or involuntary physiological ...
Simultaneous phase-correction and denoising for diffusion-weighted MRI

Kafalı, Sevgi Gökçe; Çukur, Tolga; Sarıtaş, Emine Ülkü (IEEE, 2016)

Diffusion-weighted imaging (DWI) suffers from low SNR when compared to regular MRI images. To attain reasonable SNR levels with high spatial resolution, multiple acquisitions of each slice have to be acquired. These ...
