Comparing Ultra High-Resolution CT to Conventional CT for Heart Disease

Ultra-High Resolution Computed Tomography (CT) vs. Conventional CT for Detecting Obstructive Coronary Artery Disease (CAD) The CORE-COMPARE Pilot Study

NA · Johns Hopkins University · NCT06170541

This study is testing whether a new type of heart scan called Ultra High-Resolution CT can find heart disease better than the regular CT scan in people who are at lower risk.

What this trial studies

This study evaluates the effectiveness of Ultra High-Resolution Computed Tomography (UHR-CT) compared to conventional CT in identifying obstructive coronary heart disease (CHD) in a lower-risk population. Participants will undergo a single scan using UHR-CT, which allows for the reconstruction of conventional resolution images from the same data, minimizing radiation exposure and scan time. The primary goal is to gather preliminary data to support the hypothesis that UHR-CT is superior in detecting CHD. This approach aims to justify the broader implementation of UHR-CT technology in clinical practice.

Who should consider this trial

Good fit: Ideal candidates are adults aged 21-85 with a clinical history suggestive of coronary heart disease referred for further evaluation via CT angiography.

Not a fit: Patients with known allergies to iodinated contrast media or severe heart conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved noninvasive detection of coronary heart disease, enhancing patient outcomes.

How similar studies have performed: While the specific use of UHR-CT in this context is novel, similar studies have shown promise in improving imaging techniques for cardiovascular conditions.
