Purpose The aim of this study was to investigate the visualization of small venous vessels in the normal human brain at a field strength of 3 Tesla. Methods T2*-weighted, three-dimensional gradient-echo images were acquired by exploiting the magnetic susceptibility difference between oxygenated and deoxygenated hemoglobin in the vasculature and microvasculature. The spatial resolution was 0.5 × 0.5 × 1 mm3, and sequence parameters were varied to obtain good vessel delineation. Improved… 
MR venography of the human brain using susceptibility weighted imaging at very high field strength
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.

High-resolution MR venography using 3D-PRESTO technique can clearly depict small veins and microbleeds in the human brain.
High-Resolution Three-Dimensional Contrast-Enhanced Blood Oxygenation Level-Dependent Magnetic Resonance Venography of Brain Tumors at 3 Tesla: First Clinical Experience and Comparison with 1.5 Tesla
Acquisition of CE-MRV data at 3 T enables spatial resolution to be increased within the same measurement time and with the same volume coverage compared with 1.5 T, thus providing more detailed information.
High‐resolution BOLD venographic imaging: a window into brain function
Using this method it is possible to visualize draining veins in lesions better than conventional magnetic resonance imaging methods, which often require application of a contrast medium or even conventional catheter angiography, and it may even offer the possibility of differentiating benign from malignant tumors non‐invasively.
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
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.

Improved processing of susceptibility-weighted MR phase images offers a new means of contrast for neuroimaging applications.
MR Contrast Agent at High-Field MRI (3 Tesla)
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.

MR high-resolution blood oxygenation level-dependent venography of occult (low-flow) vascular lesions.
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.

Role of high resolution in magnetic resonance (MR) imaging: Applications to MR angiography, intracranial T1‐weighted imaging, and image interpolation
The role of high‐resolution imaging has generally been limited because of the associated loss of signal‐to‐noise ratio (SNR) as voxel size decreases and imaging time increases. Despite these truths,
