Baik SH, et al. - The intention of the authors was to figure out the enhancement patterns of three-dimensional (3D) black blood (BB) contrast-enhanced magnetic resonance (MR) imaging in acute stroke patients with negative susceptibility vessel sign (SVS). Findings illustrated enhancement patterns of linear or eccentric morphology and shorter, more focal lesions by three-dimensional BB contrast-enhanced MR imaging in acute stroke patients with stenotic lesions and negative SVS.
