Key result
Gd2O3-EPL-IVUS demonstrated higher accuracy and sensitivity compared with IVUS alone in diagnosing atherosclerosis and measuring vessel size, plaque burden, and minimal lumen area.
Why the study?
Gd2O3-doped nanoparticle contrast agents have shown utility in disease diagnosis, prompting evaluation of eplerenone doped with Gd2O3 nanoparticles combined with IVUS for diagnosing patients suspected of atherosclerosis.
Does intravascular ultrasound combined with Gd2O3-eplerenone contrast agent improve diagnostic accuracy and sensitivity compared to IVUS alone in patients with suspected atherosclerosis?
Population
188 patients with suspected atherosclerosis

Does intravascular ultrasound combined with Gd2O3-eplerenone contrast agent improve diagnostic accuracy and sensitivity compared to IVUS alone in patients with suspected atherosclerosis?
The use of a novel Gd2O3-eplerenone contrast agent with intravascular ultrasound improves the diagnostic accuracy and visualization of coronary atherosclerotic plaques compared to standard IVUS.
Zhu et al. (2020) conducted a cross-sectional in Suspected atherosclerosis (n=188). Gd2O3-EPL-IVUS vs. IVUS alone was evaluated on Diagnostic accuracy and sensitivity. Gd2O3-EPL-IVUS demonstrated higher accuracy and sensitivity compared with IVUS alone in diagnosing atherosclerosis and measuring vessel size, plaque burden, and minimal lumen area.
