Feasibility and Diagnostic Performance of Voxelwise Computed Diffusion-Weighted Imaging in Breast Cancer.
Conventional diffusion-weighted imaging (DWI) with high b-values may improve lesion conspicuity, but with a low signal intensity and thus a low signal-to-noise ratio (SNR). The voxelwise computed DWI (vcDWI) may generate high-quality images with a strong lesion signal and low background. ⋯ 4 Technical Efficacy: Stage 2 J. Magn. Reson. Imaging 2018.

Multicenter StudyIntra- and interreader reproducibility of PI-RADSv2: A multireader study.
The Prostate Imaging Reporting and Data System version 2 (PI-RADSv2) has been in use since 2015; while interreader reproducibility has been studied, there has been a paucity of studies investigating the intrareader reproducibility of PI-RADSv2. ⋯ 2 Technical Efficacy: Stage 2.

Long-term reactions to pulsatile tinnitus are marked by weakened short-range functional connectivity within a brain network in the right temporal lobe.
There have been recent efforts to characterize brain functional activity features in patients with pulsatile tinnitus (PT). These efforts have revealed evidence of aberrant functional connectivity (FC) of the right middle temporal gyrus (MTG) in PT patients with prolonged disease duration. ⋯ 4 Technical Efficacy: Stage 2 J.

Meta Analysis Comparative StudyCervical spine findings on MRI in people with neck pain compared with pain-free controls: A systematic review and meta-analysis.
There is uncertainty regarding the clinical significance of findings on MRI in patients with whiplash associated disorder (WAD) or nonspecific neck pain (NSNP). ⋯ 3 Technical Efficacy: Stage 3 J. Magn. Reson. Imaging 2018.
