Computer-aided detection firm Medipattern is touting a study that compared color-flow Doppler ultrasound to standard 2D grayscale ultrasound using the company's Visualize:Vascular software, which is designed for 3D visualization of the carotid arteries.
Researchers from Montefiore Medical Center and cardiovascular imaging services provider Navix Diagnostix found that 3D reconstruction technology using Visualize:Vascular produced a statistically significant correlation between the two techniques used to calculate the reduction of the lumen.
The study compared luminal reduction as calculated by Visualize:Vascular with stenosis as inferred from velocity measurements. There was 99% correlation between velocity estimates and 3D visualization for estimating diameter reduction, Medipattern said.
Correlation for cases with less than 50% diameter reduction was 100%, while correlation for cases with 50% or greater diameter reduction was 92%.
