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

Figure 3

Contrast agent distribution in DSA images of the 80% stenosis (a- f) and without stenosis (g- l) converted in a color profile. Six identical moments evenly distributed over the passage of the contrast agent bolus are chosen to demonstrate the signal behavior for the 80% stenosis (a-f) and without stenosis (h-l).
