Toshiba introduces MRA sequence
Toshiba America Medical Systems has introduced Variable True Rate Angiography with Combined Encodings (V-TRACE), an MR angiography (MRA) sequence available on Vantage Titan systems and Vantage Atlas MR systems.
According to the company, V-TRACE assists 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. The sequence combines the advantages of both techniques to produce MRA images that depict blood vessels with both high and low velocity. The sequence design reduces the specific absorption rate, which is a measurement of heat generated to the body during a MRI. Additionally, the TOF data can be used to evaluate the brain parenchyma.
