Measuring human placental blood flow with multidelay 3D GRASE pseudocontinuous arterial spin labeling at 3T.
Placenta influences the health of both a woman and her fetus during pregnancy. Maternal blood supply to placenta can be measured noninvasively using arterial spin labeling (ASL). ⋯ 1 Technical Efficacy: Stage 2 J. Magn. Reson. Imaging 2018;47:1667-1676.

Comparative StudyDetection of liver fibrosis using qualitative and quantitative MR elastography compared to liver surface nodularity measurement, gadoxetic acid uptake, and serum markers.
Multiparametric magnetic resonance imaging (mpMRI) combining different techniques such as MR elastography (MRE) has emerged as a noninvasive approach to diagnose and stage liver fibrosis with high accuracy allowing for anatomical and functional information. ⋯ 3 Technical Efficacy: Stage 2 J. Magn. Reson. Imaging 2018;47:1552-1561.

Differential brainstem atrophy patterns in multiple sclerosis and neuromyelitis optica spectrum disorders.
Multiple sclerosis (MS) and neuromyelitis optica spectrum disorders (NMOSD) are central nervous system (CNS) inflammatory demyelinating disorders. It is clinically important to distinguish MS from NMOSD, as treatment and prognosis differ. Brainstem involvement is common in both disorders. ⋯ 2 Technical Efficacy: Stage 3 J. Magn. Reson. Imaging 2018;47:1601-1609.

Breast lesion characterization using whole-lesion histogram analysis with stretched-exponential diffusion model.
Diffusion-weighted imaging (DWI) has been studied in breast imaging and can provide more information about diffusion, perfusion and other physiological interests than standard pulse sequences. The stretched-exponential model has previously been shown to be more reliable than conventional DWI techniques, but different diagnostic sensitivities were found from study to study. ⋯ 2 Technical Efficacy: Stage 2 J. Magn. Reson. Imaging 2018;47:1701-1710.

Diffusion-weighted MRI and intravoxel incoherent motion model for diagnosis of pediatric solid abdominal tumors.
Pediatric retroperitoneal tumors in the renal bed are often large and heterogeneous, and their diagnosis based on conventional imaging alone is not possible. More advanced imaging methods, such as diffusion-weighted (DW) MRI and the use of intravoxel incoherent motion (IVIM), have the potential to provide additional biomarkers that could facilitate their noninvasive diagnosis. ⋯ 4 Technical Efficacy: Stage 2 J. Magn. Reson. Imaging 2018;47:1475-1486.
