A new technique for detecting vascular malformations, high-resolution BOLD venography (HRBV), is described. This technique relies on the BOLD principle for detecting deoxygenated blood in low-flow malformations. HRBV images are acquired using a modified 3D gradient-echo with voxel volumes of 0.5 x 0.5 x 2 mm3. The magnitude data are masked with the phase images to enhance visibility of the venous structures and are displayed using the minimum intensity projection. Preliminary results for 10…

High-Resolution MR Venography at 3.0 Tesla
Investigating the visualization of small venous vessels in the normal human brain at a field strength of 3 Tesla offers the possibility of improved resolution and the delineation of smaller vessels compared with lower field strengths.
Nonnvasive assessment of vascular architecture and function during modulated blood oxygenation using susceptibility weighted magnetic resonance imaging
The method is capable of producing high‐resolution functional maps of BOLD response to carbogen and oxygen breathing as well as high-resolution images of venous vasculature, and its sensitivity to changes in blood oxygenation was demonstrated by in vivo visualization of the BOLD effect via phase imaging.

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.
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.
Susceptibility-weighted imaging provides additional diagnostic and prognostic data in the evaluation of a wide variety of neurologic disorders including various hemorrhagic lesions seen in traumatic brain injury, coagulopathic or other hemorrhagic disorders, occult vascular malformations, stroke, hypoxicanoxic injury, neoplasms, and neurodegenerative disorders.

The MRI appearance of cavernous malformations (angiomas).
The angiographic, computerized tomography, and magnetic resonance imaging findings were compared in 10 patients with a total of 16 pathologically verified cavernous angiomas and the combination of a reticulated core of mixed signal intensity (SI) with a surrounding rim of decreased SI strongly suggests the diagnosis of a cavernous malformation.
