2D RF pulse design for optimized reduced field-of-view imaging at 1.5T and 3T

Eren, Orhun Caner; Barlas, Bahadır Alp; Sarıtaş, Emine Ülkü (Elsevier Inc., 2021-10-22)

Two-dimensional spatially selective radiofrequency (2DRF) excitation pulses are widely used for reduced field-of-view (FOV) targeted high-resolution diffusion weighted imaging (DWI), especially for anatomically small regions ...
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 ...
