Randomized Controlled Trial Multicenter Study Comparative StudyMulticenter, intra-individual comparison of single dose gadobenate dimeglumine and double dose gadopentetate dimeglumine for MR angiography of the peripheral arteries (the Peripheral VALUE Study).
To prospectively compare single dose gadobenate dimeglumine with double dose gadopentetate dimeglumine for CE-MRA in patients with peripheral arterial occlusive disease (PAOD) using an intra-individual crossover study design in which all patients received both contrast agents in otherwise identical CE-MRA examinations. ⋯ Image quality and diagnostic performance on peripheral CE-MRA with 0.1 mmol/kg gadobenate dimeglumine is at least equivalent to that with 0.2 mmol/kg gadopentetate dimeglumine.

Characterization and limitations of diffusion tensor imaging metrics in the cervical spinal cord in neurologically intact subjects.
To characterize diffusion tensor imaging (DTI) metrics across all levels of the cervical spinal cord (CSC) and to study the impact of age and signal quality on these metrics. ⋯ This study provides DTI data for GM and WM funiculi throughout the CSC. While DTI metrics may be used to define cord pathology, variations in metrics due to age and signal quality need to be accounted for before making definitive conclusions.

To evaluate a new fat suppression technique using multiple fat suppression pulses intended for breast dynamic contrast-enhanced (DCE) imaging using segmented three-dimensional fast field echo (FFE). ⋯ DFS is a promising fat suppression technique for breast imaging even in regions with B1 (+) inhomogeneity.
