Plaque View: Plaque Characterization Analysis
We have developed MRI and Ultrasound plaque characterization software tools for users to efficiently interpret the atherosclerosis studies.
MRI-PlaqueViewTM has been FDA cleared for clinical management of carotid atherosclerosis, while also being used in research of atherosclerosis in aorta, peripheral, and other arteries. The software uses patented algorithms to characterize and measure plaque morphology, plaque burden, plaque composition and components.
MRI-PlaqueView guides the user through a sequence of intuitive and optimized characterization steps. Within minutes, all vessel walls are identified, multiple contrast weightings are aligned, internal plaque composition / components, such as soft or calcified plaques and intraplaque hemorrhage , are characterized, and measurements of plaque morphology, including thickness, area, distance, and stenosis are recorded.
3D visualizations portray the plaque morphology and composition not seen with MRI angiography, and the plaque visualizations are displayed in context with traditional MIP views of MRA data.
A report captures the key findings of plaque characterization in a concise format to be readily used by vascular surgeons, neurosurgeons, neurologists, interventionalists, or cardiologists for vascular disease management and research.
Order Information: MRI-PlaqueViewTM is available with four packages, ranging from Plaque Burden Analysis, Intraplaque Hemorrhage Analysis, Plaque Analysis, to Auto Plaque Analysis. It can be purchased on a per-use basis which requires less up-front payments, or with a product license without usage restrictions. For further information, please download MRI Plaque View brochure and Contact Us to arrange free consultation, demo and evaluation.
Atherosclerosis imaging and characterization using MRI-Plaque View can be readily conducted on the following vendors’ MRI scanners:
- GE MR : HDxt , Discovery MR750 – Application Technical Details;
- Philips MR : Achieva – Application Technical Details ;
MRI-PlaqueView has been reviewed in Technical Brief: Vulnerable Atherosclerotic Plaque issued by AHRQ of U.S. Department of Health and Human Services (HHS).
VPDiagnostics is also leading an NIH-sponsored 14-center carotid atherosclerosis prospective trial to evaluate MRI-PlaqueView in stratifying the future risk of stroke. This trial has been reviewed in Arteriosclerosis Global Clinical Trials Review, Q4, 2010 by MarketResearch.com.
