CONTRAST 2

This study delves into the efficacy of different contrast injection methods for coronary CT angiography (CCTA), aiming for consistent enhancement levels crucial in analyzing coronary artery plaque quantitatively. The comparison among standard test bolus, optimized test bolus, and body weight-based protocols reveals compelling results. The optimized test bolus protocol stands out, showcasing superior consistency and enhanced levels compared to others. Notably, it significantly reduces variation in coronary enhancement and achieves a higher percentage of scans within the desired attenuation range. Its precision in coronary attenuation and contrast timing suggests a potential paradigm shift in CCTA precision, potentially reshaping clinical approaches toward more reliable quantitative assessment of coronary artery plaque.
