The QVA (Quantitative Vascular Analysis) workflow offers fast and intuitive peripheral vessel analysis, including the abdominal aorta and the carotid, renal, iliac and femoral arteries. The QVA workflow features single vessel analysis including calibration, contour detection and quantification of severity of stenosis to diagnose and select the right treatment for your patient.

Key Product Features

  • Quantification of lesion length
  • Quantification of percentage stenosis

QVA for research

The QVA workflow can be extended with research functionality. The QVA for Research workflow has additional functionality for use in research studies. Drug Eluting Stent (DES) analysis enables you to evaluate restenosis and edge effects in pre-, post- and follow-up studies. User Defined Subsegment (UDS) analysis offers the user the option to divide the vessel under study into multiple subsegments. QVA for Research facilitates accurate and reproducible analyses in (multi center) research studies in a fast and user-friendly way.

Extra key product features in QVA for research

  • Evaluation of restenosis and edge effects on Drug Eluting Stents
  • Evaluation of overlap for Drug Eluting Balloons
  • Independent evaluation of multiple segments within one vessel part.

Key Results

  • Minimum Luminal Diameter
  • Reference Diameter
  • % Diameter Stenosis
  • Length stenotic segment
  • Area at MLD

Extra key results in QVA for research

  • Dedicated segment models
  • Single vessel results can be displayed in the Drug Eluting Stent model.
