Randomized Controlled Trial Multicenter Study Comparative StudyEnhancement of liver parenchyma after injection of hepatocyte-specific MRI contrast media: a comparison of gadoxetic acid and gadobenate dimeglumine.
To compare enhancement of liver parenchyma in MR imaging after injection of hepatocyte-specific contrast media. ⋯ In the delayed, hepatocyte-specific phase, liver enhancement after injection of gadoxetic acid was superior to that obtained with gadobenate dimeglumine.

Randomized Controlled Trial Multicenter Study Comparative StudyComparison of gadodiamide-enhanced MR angiography to intraarterial digital subtraction angiography for evaluation of renal artery stenosis: results of a phase III multicenter trial.
To evaluate the efficacy and safety of 0.1 mmol/kg gadodiamide administration for contrast-enhanced magnetic resonance angiography (MRA) in detecting hemodynamically relevant renal artery stenosis (RAS) when compared with intraarterial digital subtraction angiography (IA-DSA) as the gold standard. ⋯ Gadodiamide administration at the labeled dose of 0.1 mmol/kg for contrast-enhanced MRA achieved equivalent results compared to IA-DSA in evaluation of RAS and was well tolerated.

Improved blood suppression in three-dimensional (3D) fast spin-echo (FSE) vessel wall imaging using a combination of double inversion-recovery (DIR) and diffusion sensitizing gradient (DSG) preparations.
To provide improved blood suppression in three-dimensional inner-volume fast spin-echo (3D IV-FSE) carotid vessel wall imaging by using a hybrid preparation consisting of double inversion-recovery (DIR) and diffusion sensitizing gradients (DSG). ⋯ A combination of DIR and DSG preparations can provide improved blood suppression and lumen-wall CNR(eff) for 3D IV-FSE vessel wall imaging.

T1-weighted-SPACE dark blood whole body magnetic resonance angiography (DB-WBMRA): initial experience.
To evaluate the feasibility of the dark blood fast spin echo (FSE) T1-weighted-Sampling Perfection with Application of optimized Contrasts using different flip angle Evolution (T1w-SPACE) sequence in assessing whole body arterial wall information from the extracranial carotids to the popliteal artery. ⋯ DB-WBMRA using T1w-SPACE is feasible and can be performed with a high degree of reliability.

Topography mapping of whole body adipose tissue using A fully automated and standardized procedure.
To obtain quantitative measures of human body fat compartments from whole body MR datasets for the risk estimation in subjects prone to metabolic diseases without the need of any user interaction or expert knowledge. ⋯ The proposed algorithm enables the reliable and completely automatic creation of adipose tissue distribution profiles of the whole body from multislice MR datasets, reducing whole examination and analysis time to less than half an hour.
