Quantitative Susceptibility Mapping for Characterization of Intraplaque Hemorrhage and Calcification in Carotid Atherosclerotic Disease.
Carotid artery intraplaque hemorrhage (IPH), an unstable component of atherosclerosis, is associated with an increased risk of stroke. ⋯ QSM is a novel imaging tool for the identification of IPH in patients with carotid atherosclerosis and enables differentiation of IPH and calcification. EVIDENCE LEVEL: 1 TECHNICAL EFFICACY: Stage 1 J. Magn. Reson. Imaging 2020;52:534-541.

Diagnosis and Grading of Prostate Cancer by Relaxation Maps From Synthetic MRI.
The interpretation system for prostate MRI is largely based on qualitative image contrast of different tissue types. Therefore, a fast, standardized, and robust quantitative technique is necessary. Synthetic MRI is capable of quantifying multiple relaxation parameters, which might have potential applications in prostate cancer (PCa). ⋯ 2 Technical Efficacy Stage: 2 J. Magn. Reson. Imaging 2020;52:552-564.

Improved quantification of myelin water fraction using joint sparsity of T2 * distribution.
Myelin water fraction (MWF) can be quantified with analysis of the T2 * distribution, whereas deducing the T2 * spectrum from several echoes is an underdetermined and ill-posed problem. ⋯ 2 Technical Efficacy: Stage 1 J. Magn. Reson. Imaging 2020;52:146-158.

Multiparametric MRI Evaluation of Liposomal Prostaglandins E1 Intervention on Hepatic Warm Ischemia-Reperfusion Injury in Rabbits.
Liposomal prostaglandin E1 (Lipo-PGE1) treatment should protect against hepatic warm ischemia-reperfusion injury (WIRI). Improved methods are needed for the noninvasive evaluation of hepatic responses to prophylactic Lipo-PGE1 pretreatment approaches. ⋯ 1 Technical Efficacy Stage: 2 J. Magn. Reson. Imaging 2020;52:217-228.
