Exploring the Value of Using Color-Coded Quantitative DSA Evaluation on Bilateral Common Carotid Arteries in Predicting the Reliability of Intra-Ascending Aorta Flat Detector CT–CBV Maps

Abstract

This preliminary study showed good correlation between relative area under the curve from color-coded quantitative DSA and relative CBV from CBV maps. Color-coded quantitative DSA potentially helped sort out patients whose vascular anatomy could support reliable CBV acquisitions of flat detector CT by injecting contrast medium into the ascending aorta.

Reliability and Accuracy of Peri-Interventional Stenosis Grading in Peripheral Artery Disease Using Color-Coded Quantitative Fluoroscopy: A Phantom Study Comparing a Clinical and Scientific Postprocessing Software

“…Blood has a higher viscosity and less tendencies to turbulent flow. Nevertheless under physiological conditions high-grade stenosis (80% stenosis) is known to demonstrate turbulent flows and simplification by neglecting some features of complex fluid dynamics is not uncommon in these kinds of studies [ 18 , 19 , 28 , 29 ]. Second, the material properties of the used stenosis and the flow through the stenosis do not conform to the properties and conditions of human blood vessels.…”

Effect of low-intensity pulsed ultrasound after intraoral vertical ramus osteotomy

“…Quantitative color mapping of CT extends a wide range of applications in the medical and dental fields. Recently, it has been used to for the evaluation of the arterial enhancement fraction of the liver, 18,19 diagnosis of coronary artery disease, 20 prediction of intra-ascending aorta 21 and the analysis of bone properties in hip osteoarthritis. 22 Meyer et al 23 provided evidence that assessing the degree and location of osseointegration of dental implants are valid using quantitative color mapping of the CT.…”

X-ray angiography perfusion imaging with an intra-arterial injection: comparative study with15O-gas/water positron emission tomography

“…This discrepancy may have occurred because the AUC shows the total distribution of the amount of contrast present in the hemisphere, with the volume data being imprecise in XAP as they are based on two-dimensional angiography. Additionally, the quantity of contrast reaching the hemisphere through the pigtail catheter placed in the ascending aorta may be influenced by the anatomical environment 18. These factors can influence the values of rWiR.…”
