TY - JOUR T1 - Determination of blood flow direction using velocity-phase image display with 3-D phase-contrast MR angiography. JF - American Journal of Neuroradiology JO - Am. J. Neuroradiol. SP - 1435 LP - 1438 VL - 13 IS - 5 AU - J R Pernicone AU - J E Siebert AU - T A Laird AU - T L Rosenbaum AU - E J Potchen Y1 - 1992/09/01 UR - http://www.ajnr.org/content/13/5/1435.abstract N2 - The authors describe their use of phase-contrast MRA to depict vascular anatomy and to define the direction of blood flow. Documentation of flow reversal can provide information regarding prognosis and can facilitate surgical planning. The technique requires no additional scan-time. ER -
