Differences in Different Reconstruction Algorithms for Coronary CTA Demonstrating Pericoronary Adipose Tissue Attenuation

This study evaluated the differences in Fat Attenuation Index (FAI), a sensitive biomarker for coronary inflammation, using three reconstruction algorithms: DLIR-H, ASIR-V, and FBP. The population was divided into groups based on plaque presence, and attenuation values, image noise, and FAI were measured. DLIR-H demonstrated the highest FAI and the strongest ability to reduce image noise, while FBP yielded the lowest FAI. These findings highlight the importance of standardized reconstruction protocols in multicentre and longitudinal studies to ensure accurate and comparable FAI results, crucial for advancing cardiac assessments.
