New MR Systems Allow for Safer MRA Exams

Patients with renal insufficiency or who are concerned about the use of contrast during MRA exams now can visit Texas Health Huguley Hospital Fort Worth South for safer, more effective exams. Texas Health Huguley has acquired the Vantage Titan 1.5T from Toshiba America Medical Systems, Inc. that limits use of contrast during an MRA exam.  Contrast-free imaging is particularly important because gadolinium, the common contrast agent used for magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) exams, recently has been directly linked to nephrogenic systemic fibrosis also known as nephrogenic fibrosing dermopathy (NSF/NFD), a sometimes fatal disease that occurs in patients with renal insufficiency.  According to a study by Yale University, 95 percent of the study’s NSF/NFD patient pool had received gadolinium within three months of the disease’s onset.

“With Toshiba’s contrast-free imaging techniques, we now can perform MRA procedures and capture images superior to those acquired through techniques that require contrast agents,” said Diane Hanson, Imaging Services Director of Texas Health Huguley.“We are proud to be able to offer this latest technology to our community.”

The Vantage Titan 1.5T utilizes four proprietary contrast-free imaging techniques that make it possible to image the arteries and veins at the same time, but displays them separately, which allows physicians to more accurately diagnose diseases that may have both arterial and venous components.
