Improved cerebrospinal fluid suppression for intracranial vessel wall MRI.
To develop and assess a three-dimensional (3D) high resolution black blood MRI (BBMRI) method for evaluation of intracranial vessels with improved cerebrospinal fluid (CSF) suppression. ⋯ The 3D ADE-BBMRI provides excellent blood and CSF suppression, and accurate measurements of intracranial vessels at 0.5 mm isotropic resolution in 5 min. Its clinical application may provide insight into stroke risk. J. Magn. Reson. Imaging 2016;44:665-672.

In vivo imaging of the spectral line broadening of the human lung in a single breathhold.
To present a technique, which allows for the in vivo quantification of the spectral line broadening of the human lung in a single breathhold. The line broadening is an interesting parameter of the lung because it can provide information about important lung properties, namely: inflation and oxygen uptake. The proposed technique integrates the asymmetric spin-echo (ASE) approach, which is commonly used to quantify the line broadening, with a single shot turbo spin-echo pulse sequence with half-Fourier acquisition (HASTE), to reduce the acquisition times. ⋯ The presented technique offers a robust way to quantify the spectral line broadening of the human lung in vivo. Image acquisition can be accomplished in a single breathhold, which could be suitable for clinical applications on patients with lung diseases. J. Magn. Reson. Imaging 2016;44:745-757.

Value of preoperative 3T multiparametric MRI for surgical margin status in patients with prostate cancer.
To examine the value of preoperative multiparametric magnetic resonance imaging (MRI) as a predictor of surgical margin (SM) status in patients with prostate cancer (PC). ⋯ PC with positive SM was characterized by tumor extension in the apical and proximal regions, lower tumor ADC, and tumors with positive MRI findings of ECE, compared to tumors with negative SM.

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.
