Multimodality Imaging in Coronary Artery Disease: Focus on Computed Tomography

Area of Science:

• Cardiovascular imaging
• Radiology
• Medical diagnostics

Background:

• Coronary artery disease (CAD) is a major global health concern, driving mortality worldwide.
• Traditional diagnostic methods for CAD exist, but advancements are crucial.
• Computed tomography (CT) technology has significantly improved cardiac imaging capabilities.

Purpose of the Study:

• To review the role of CT in assessing coronary artery disease (CAD).
• To explore various CT-based imaging modalities for CAD evaluation.
• To discuss the implications, benefits, limitations, and future of these CT techniques.

Main Methods:

• Review of current literature on cardiac CT imaging for CAD.
• Focus on specific CT modalities: coronary artery calcium screening, coronary CT angiography, myocardial CT perfusion, and fractional flow reserve CT.
• Analysis of clinical applications, advantages, and disadvantages of each method.

Main Results:

• Cardiac CT provides accurate and noninvasive evaluation of CAD.
• Specific CT techniques offer detailed insights into coronary artery calcification, anatomy, and myocardial blood flow.
• Fractional flow reserve CT (FFR-CT) shows promise in functional assessment.

Conclusions:

• CT-based imaging is a valuable tool for diagnosing and assessing the severity of CAD.
• Each modality offers unique benefits and has specific limitations.
• Continued technological advancements in CT will likely expand its role in cardiovascular care.
