Comparison of Digital Flat-Panel Detector and Conventional Angiography Machines: Evaluation of Stent Detection Rates, Visibility Scores, and Dose-Area Products

Abstract

The objective correct stent detection rates were similar for both machines with differences in detection for the respective stents. The subjective radiopacity scores were almost always better for the Fluorospot TOP machine. Also, the Axiom Artis machine generated approximately 90% higher radiation doses in fluoroscopy. For both machines, using a higher fluoroscopy pulsing frequency had no positive effect on objective correct stent detection rates or subjective radiopacity scores.
