Toshiba America Medical Systems of Tustin, CA, has introduced variable true rate angiography with combined encodings (V-TRACE), an MR angiography (MRA) sequence available on all Vantage Titan and Vantage Atlas MRI systems.
V-TRACE is designed to streamline MRA brain imaging by acquiring four image contrasts in one sequence, providing an imaging application for visualizing slow- and fast-flow vessels separately and together, as well as the brain tissue surrounding the vessels.
V-TRACE MRA is a dual-echo 3D FE sequence in which the first echo is acquired using time-of-flight (TOF) and the second echo is acquired using flow-sensitive black blood (FSBB). The sequence combines both techniques to produce MRA images that depict blood vessels with both high and low velocity.
