3T chemical shift-encoded MRI: Detection of altered proximal femur marrow adipose tissue composition in glucocorticoid users and validation with magnetic resonance spectroscopy.
Osteoporosis (OP) results in weak bone and can ultimately lead to fracture. Drugs such as glucocorticoids can also induce OP (glucocorticoid-induced osteoporosis [GIO]). Bone marrow adipose tissue composition and quantity may play a role in OP pathophysiology, but has not been thoroughly studied in GIO compared to primary OP. ⋯ 2 Technical Efficacy: Stage 2 J. Magn. Reson. Imaging 2019;50:490-496.

Diurnal variability of cerebral metabolites in healthy human brain with 2D localized correlation spectroscopy (2D L-COSY).
Two-dimensional localized correlation spectroscopy (2D L-COSY) is a research tool that has been applied to evaluate in vivo metabolic activity in many neurological and oncological disorders. Circadian mediators such as brain temperature, hydration, and osmotic regulation have been claimed to change metabolic profiles. ⋯ 1 Technical Efficacy Stage: 1 J. Magn. Reson. Imaging 2019;50:592-601.

Assessing the performance of benign and malignant breast lesion classification with bilateral TIC differentiation and other effective features in DCE-MRI.
Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) is increasingly being used to detect and diagnose breast cancer. However, the effective methods based on quantitative feature analysis need to be explored. ⋯ 1 Technical Efficacy: Stage 2 J. Magn. Reson. Imaging 2019;50:465-473.

Probing structure of normal and malignant prostate tissue before and after radiation therapy with luminal water fraction and diffusion-weighted MRI.
Interpretation of diffusion in conjunction with T2 -weighted MRI is essential for assessing prostate cancer; however, the combination of apparent diffusion coefficient (ADC) with quantitative T2 mapping remains unexplored. ⋯ 2 Technical Efficacy: Stage 2 J. Magn. Reson. Imaging 2019;50:619-627.
