Flow velocity quantitation using inversion tagging of multiple magnetization boli is a robust technique capable of providing velocity determinations in tortuous vessels.
Inversion tagging is a robust method for quantifying flow velocities, even in tortuous vessels.
May support velocity mapping in tortuous vessels; leaves open clinical validation before routine adoption.
A method for quantitating flow velocities is presented. The technique tags multiple boli of magnetization in transit across a thick selection slab using rf inversion pulses. Results in phantoms and in vivo demonstrate that the method is robust and can provide velocity determinations in tortuous vessels.
