Multicenter StudyPhase 3 efficacy and safety trial of gadobutrol, a 1.0 molar macrocyclic MR imaging contrast agent, in patients referred for contrast-enhanced MR imaging of the central nervous system.
Gadobutrol is a 1.0 M macrocyclic magnetic resonance imaging (MRI) contrast agent. A study was performed to evaluate the efficacy and safety of gadobutrol-enhanced versus unenhanced imaging for central nervous system (CNS) lesion visualization and detection. ⋯ Gadobutrol 1.0M is an effective and well-tolerated contrast agent for CNS MRI.

Usefulness of thin-section single-shot turbo spin echo with half-Fourier acquisition in evaluation of local invasion of lung cancer.
To evaluate the usefulness of thin-section single-shot turbo spin echo with half-Fourier acquisition (SS-TSE-HF) alone for evaluation of local invasion of lung cancer. ⋯ Thin-section SS-TSE-HF sequence alone without any contrast agent demonstrated a relatively high diagnostic performance in evaluation of local invasion of lung cancer.

Motion-compensated real-time MR thermometry augmented by tracking coils.
To develop and evaluate a real-time proton resonant frequency (PRF) based MR thermometry method with a novel motion compensation technique, using linear phase model and active tracking coils. ⋯ The new MR thermometry method using catheter-based tracking coils and linear phase model for motion compensation and phase correction is promising and may offer reliable MR thermometry for real-time MRI-guided thermal therapies.

Comparative StudyMRI of the carotid artery at 7 Tesla: quantitative comparison with 3 Tesla.
To evaluate the 7 Tesla (T) MRI of the carotid arteries, as quantitatively compared with 3T. ⋯ Evaluation between 3T and 7T carotid MRI with optimized setups at both field strengths showed improved SNR at 7T, an increase in vessel wall T1 and a decrease in vessel wall T2.
