QISS

A disruptive leap in non-contrast MR Angiography

Imaging Diabetics with MR

About 347 million people worldwide have diabetes.1 In many cases this leads to perihperal artery disease.

"The high prevalance of chronic renal impairment in diabetic patients with PAD and the need for high doses of gadolinium based contrast agents place them at risk for nephrogenic system fibrosis."2

QISS3 provides an accurate non-contrast alternative to CE-MRA for demonstrating clinically significant arterial disease in patients where contrast agents are contraindicated.2,4 Enhance clinical capabilities with access to latest clinical standards of care and improve patient safety with the reduced need for CE-MRA.

"QISS MRA should become the non-contrast MRA technique of choice in patients with renal dysfunction."5
