High-Resolution MR Venography at 3.0 Tesla
Journal of computer assisted tomography
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 mm 3 , and sequence parameters were varied to obtain good vessel delineation.
