Already among the leading developers of contrast-free magnetic resonance angiography (MRA) techniques, Toshiba America Medical Systems, Inc., has introduced a fourth generation contrast-free imaging technique, Time and Space Angiography (TSA).

Adding to the robust offering of contrast-free techniques from Toshiba, TSA creates images that show dynamic blood flow without using contrast agents. .
TSA will have a variety of clinical benefits to improve both diagnostic confidence and patient care and safety. TSA builds upon the pioneering Time-Spatial Labeling Inversion Pulse (Time-SLIP) technique and is especially desirable for patients with compromised circulations and renal flow problems. It features an extremely high temporal resolution and a continually changing inversion pulse time, creating dynamic images showing blood flow in motion.


In patients with symptoms of stroke, TSA is able to show blood flow into the brain and clearly display the area being impeded, which aids physicians in faster, more accurate diagnosis. For neurologists, the use of TSA will enable the diagnosis of cerebral spinal fluid diseases non-invasively.

"We have been at the forefront of contrast-free imaging, offering our customers safe, contrast-free techniques that capture images equal to, and in many cases superior to, images captured using contrast," said Bob Giegerich, director, MR Business Unit, Toshiba. "We are fully committed to patient safety and continue to create new contrast-free MRA techniques that are advancing the industry."
