Quantitative Coronary Analysis (QCA)/Quantitative Vessel Analysis (QVA)
Independent analysis of angiograms has always been and continues to remain the gold standard for the clinical research end point assessment of coronary / peripheral artery disease. At Vibgyor, the Angiography Core laboratory provides established analysis techniques to deliver objective and reproducible measurements of coronary/peripheral artery dimensions. Our QCA/QVA Core Lab offers support by providing an unbiased interpretation of the results of pharmaceutical or mechanical intervention in artery disease, as recorded cineangiographically.
The advantages offered by the QCA/QVA core lab for Quality control involve review, skilled protocol specific analysis, and post review of images; approval of each analysis by highly experienced cardiologists; and interim-final database generation and export to sponsor.
The CoreLab employs an industry-leading software platform for the analysis of coronary/peripheral vessels in angiograms that provides support to researchers with a solid basis for the assessment of new therapies. The technology platform is a flexible modular structure which makes it possible to add combinations of functionality to the basic modules for coronary vessel analysis.
The key features are as follows :
- Automatic analysis of straight, ostial and bifurcated segments
- Fast, two-click and three-click automatic pathline detection and superb automatic contour detection
- Analysis of straight vessel segments treated with (drug eluting) stents or vascular brachy therapy
- Subsegment and edge segment analyses
- Analysis of standard digital, subtracted and inverted images
- Three wall-motion reference models: Centerline, Stanford, and Slager
- Audit-trailing to safeguard standard working procedures
- DataConvert for conversion of XML or DICOM analysis results to various formats, including HTML and Microsoft Excel XML
