CAD-RADS: A Standardized Reporting System for Coronary CT Angiography

Area of Science:

• Cardiovascular Imaging
• Radiology
• Medical Informatics

Background:

• Coronary CT angiography (CTA) is a validated noninvasive method for diagnosing coronary artery disease (CAD).
• Standardization in reporting CTA findings is crucial for consistent interpretation and clinical application.
• Existing reporting methods lack uniformity, potentially leading to varied clinical decisions.

Purpose of the Study:

• To introduce and explain the Coronary Artery Disease Reporting and Data System (CAD-RADS).
• To outline the structure and application of the CAD-RADS classification for coronary CTA.
• To highlight the benefits of CAD-RADS in standardizing interpretation and guiding clinical management.

Main Methods:

• Development of a standardized reporting system (CAD-RADS) for coronary CTA.
• Categorization of findings based on lesion severity, from CAD-RADS 0 to CAD-RADS 5.
• Integration of clinical management recommendations with each CAD-RADS category.

Main Results:

• The CAD-RADS system provides a structured approach to interpreting coronary CTA.
• It classifies coronary artery lesions based on the most severe finding, aiding in risk stratification.
• The system offers clear management guidelines linked to specific classifications.

Conclusions:

• CAD-RADS enhances the standardization of coronary CTA interpretation and reporting.
• It improves communication between radiologists and clinicians, leading to consistent decision-making.
• The system promotes appropriate use of invasive procedures by increasing diagnostic accuracy.
