High‐SNR multiple T₂(*)‐contrast magnetic resonance imaging using a robust denoising method based on tissue characteristics

Abstract

This study demonstrates that high-SNR multiple T (*)-contrast MR images can be obtained using our denoising method based on tissue characteristics without noticeable artifacts. Evidence level: 2 J. MAGN. RESON. IMAGING 2017;45:1835-1845.

Quality evaluation of no‐reference MR images using multidirectional filters and image statistics

“…Some of these fast‐acquisition techniques and high‐quality image‐production methods include non‐Cartesian acquisition , parallel imaging , compressed sensing , synthetic MRI , MR fingerprinting , motion artifact correction , and denoising techniques . Despite these advances, MR‐image quality may still depend on the type of acquisition hardware , the method of acquisition (1–4), the condition of the patient , the scanning time , the reconstruction algorithm , and the postprocessing technique . As many factors affect MR‐image production, an evaluation of overall MR image quality is not simple .…”
