Comparative StudyUse of intravoxel incoherent motion MRI to assess renal fibrosis in a rat model of unilateral ureteral obstruction.
To investigate the potential of intravoxel incoherent motion (IVIM) magnetic resonance imaging (MRI) in assessment of renal fibrosis using a rat model of unilateral ureteral obstruction (UUO). ⋯ IVIM MRI shows great potential in noninvasive assessment of renal fibrosis induced by UUO.

Diffusion-weighted multiparametric MRI for monitoring longitudinal changes of parameters in rabbit VX2 liver tumors.
To investigate the value of different quantitative models of diffusion-weighted multiparametric imaging (DW-MPI) including traditional as well as several advanced models for monitoring the longitudinal parameter changes in rabbit liver VX2 carcinoma and for correlating the perfusion-related imaging parameters to vascularity of tumor tissue. ⋯ ADC, f, and KDKI were identified as the most promising parameters for monitoring changes in rabbit liver VX2 carcinoma and f and ADC showed highest correlation with MVD.

Initial experience of generalized intravoxel incoherent motion imaging and diffusion tensor imaging (GIVIM-DTI) in healthy subjects.
To evaluate the feasibility of combined generalized intravoxel incoherent imaging and diffusion tensor imaging (GIVIM-DTI) to access the renal microstructure and microcirculation with respiratory triggering. ⋯ GIVIM-DTI shows promise for advancing the characterization of the renal microstructure and microcirculation.

Hybrid imaging with integrated positron emission tomography (PET) and magnetic resonance imaging (MRI) combines the advantages of the high-resolution anatomic data from MRI and functional imaging data from PET, and has the potential to improve the diagnostic evaluation of various types of cancers. The clinical oncologic applications of this newest hybrid imaging technology are evolving and substantial efforts are underway to define the role of PET/MRI in routine clinical use. The current published literature suggests that PET/MRI may play an important role in the evaluation of patients with certain types of malignancies, involving anatomic locations such as the pelvis and the liver. ⋯ Magn. Reson. Imaging 2016;44:265-276.

Does hydration status affect MRI measures of brain volume or water content?
To determine whether differences in hydration state, which could arise from routine clinical procedures such as overnight fasting, affect brain total water content (TWC) and brain volume measured with magnetic resonance imaging (MRI). ⋯ We demonstrate that within a range of physiologic conditions commonly encountered in routine clinical scans (no pretreatment with hydration, well hydrated before MRI, and overnight fasting), brain TWC and brain volumes are not substantially affected in a healthy control cohort.
