High Resolution Magnetic Resonance Venography at 3 Tesla: Optimized Acquisition, Reconstruction, and Post-processing

Magnetic resonance venography (MRV) based on susceptibility weighted imaging can be used for detailed study of intracranial venous vasculature. The main problems with the existing MRV techniques are long scan time (20 minutes and longer) and poor visibility of small veins due to relatively large voxel volume (0.25 mm3 or larger). The composite method for intracranial MRV including optimized data acquisition, image reconstruction, and post-processing has been developed and successfully applied to more than 20 studies. The method allows acquisition of high quality venograms with improved small vessel visibility in acceptable scan time (less than 10 minutes).
