QISSA disruptive leap in non-contrast MR Angiography

More than 200 million people worldwide suffer from peripheral arterial disease (PAD).1,2

Contraindication of contrast media makes it challenging to diagnose a large number of these patients.

Overcome these current limitations and enhance your clinical capabilities with QISS, a completely new non-contrast MR Angiography technique.

QISS aids in improving patient safety and compliance for higher accuracy3 and better disease management, while maintaining the diagnostic certainty you need in peripheral MRA exams.

Eigenschaften & Vorteile

Planning and execution of CE-MRA requires a high degree of expertise to prevent venous inflow and other artifacts, caused by suboptimal timing of contrast media injection, for example.

With Set-n-go implementation, "QISS provides an easy-to-handle approach for imaging peripheral arteries with little requirements for further adjustments".1 Additionally, QISS2 offers the potential to save operational costs of up to $180 / patient by omitting disposables, contrast agent and lab tests (GFR).3

Set'n'Go workflow

The software package for non-contrast enhanced peripheral MR Angiography is based on quiescent interval single-shot imaging.

  • ECG triggered
  • Robust, 2D non-subtractive technology
  • Set-n-go implementation (Dot software add-in) for easy application
  • Export all images in one series (Combined View, CT-like)

Klinische Anwendung

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.
