Rationale and ObjectivesTo evaluate the clinical potential of high-resolution 3D contrast-enhanced blood oxygenation level-dependent MR-Venography (CE-MRV) for primary brain tumors and metastases at 3 Tesla (T) in comparison to 1.5 T. MethodsEighteen patients with brain tumors were examined using CE-MRV after application of a standard dose of MRI contrast agent (0.1 mmol/kg gadodiamide). CE-MRV is based on a high-resolution 3D flow-compensated gradient-echo sequence with long echo times that…

Contrast-Enhanced, High-Resolution, Susceptibility-Weighted Magnetic Resonance Imaging of the Brain: Dose-Dependent Optimization At 3 Tesla and 1.5 Tesla In Healthy Volunteers
TLDR
Only a standard dose (0.1 mmol/kg) of gadobenate dimeglumine is required to achieve the optimum susceptibility effect and image quality at 3 T, together with a reduced scan time.
MR Contrast Agent at High-Field MRI (3 Tesla)
TLDR
Administration of gadolinium-based contrast agent produces higher contrast between tumor and normal brain at 3 T than at 1.5 T, helps to detect more cerebral metastases in patients with primary and secondary brain tumors, improves the evaluation of macroadenomas of the hypophysis, and makes MR venography at 3T clinically attractive with increase in spatial resolution within the same measurement time.
High-field, high-resolution, susceptibility-weighted magnetic resonance imaging: improved image quality by addition of contrast agent and higher field strength in patients with brain tumors
TLDR
The intravenous administration of MultiHance, an agent with high relaxivity, allowed a reduction of scan time from 9 min to 7 min while preserving excellent susceptibility effects and image quality in SW images obtained at 3 T.
High-Resolution Contrast-Enhanced, Susceptibility-Weighted MR Imaging at 3T in Patients with Brain Tumors: Correlation with Positron-Emission Tomography and Histopathologic Findings
TLDR
3T HR-CE-SW-MR imaging shows both intratumoral SusE not visible with standard MR imaging and contrast enhancement visible withstandard MR imaging, and this novel technique is a promising tool for noninvasive differentiation of low-grade from high-grade brain tumors and for determination of an optimal area of biopsy for accurate tumor grading.
Improved Preoperative Evaluation of Cerebral Cavernomas by High-Field, High-Resolution Susceptibility-Weighted Magnetic Resonance Imaging at 3 Tesla: Comparison With Standard (1.5 T) Magnetic Resonance Imaging and Correlation With Histopathological Findings—Preliminary Results
TLDR
Compared with standard (1.5 T) MRI, 3 T HR-SW-MRI allows superior detection and characterization of cerebral cavernomas and, despite increased susceptibility effects, signal loss at higher magnetic field strengths, the visualization of intralesional tubular structures is feasible.
The optimal use of contrast agents at high field MRI
TLDR
Whereas a double dose of conventional gadolinium-based contrast agents was optimal in SWI with respect to sensitivity and image quality, a standard dose of gadobenate dimeglumine, which has a two-fold higher T1-relaxivity in blood, produced the same effect.
Magnetic Resonance Imaging of the Pancreas at 3.0 Tesla: Qualitative and Quantitative Comparison With 1.5 Tesla
TLDR
The results suggest that 3.0 T may offer promise for improved body MRI, although further technical development to optimize SNR and improve signal homogeneity will be needed before its full potential can be achieved.
Combination of high-resolution susceptibility-weighted imaging and the apparent diffusion coefficient: added value to brain tumour imaging and clinical feasibility of non-contrast MRI at 3 T.
TLDR
The addition of both high-resolution susceptibility-weighted imaging and the apparent diffusion coefficient improved the diagnostic performance of the contrast MR protocol for brain tumour imaging and could be feasible in selected patients who cannot tolerate a contrast agent.
Magnetic susceptibility-weighted MR phase imaging of the human brain.
TLDR
Improved processing of susceptibility-weighted MR phase images offers a new means of contrast for neuroimaging applications.
MR venography of the human brain using susceptibility weighted imaging at very high field strength
TLDR
By applying optimised vessel filters (vesselness filter and vessel enhancing diffusion) whole brain MR venograms can be obtained at 7 T with a significantly reduced measurement time compared to 3 T.

Magnetic Resonance Imaging Contrast Enhancement of Brain Tumors at 3 Tesla Versus 1.5 Tesla
TLDR
Administration of a gadolinium contrast agent produces higher contrast between tumor and normal brain at 3 tesla than at 1.5 tesLA, and Signal enhancement of the lesions in T1-SE sequences was not significantly different between both field strengths.

TLDR
Preliminary results for 10 patients show that HRBV is more sensitive in detecting cavernomas than is T2-weighted imaging, and lesions that are presumed to be telangiectasias are detected only with this technique.
