AbstractBackground: Coronary computed tomographic angiography (CCTA) is increasingly used to examine coronary artery disease (CAD) due to its non-invasiveness, significant negative predictive value in ruling out major CAD, and recent technological advances. The purpose of this research was to compare CAD-RAD standardized vocabulary for CT coronary angiography ratings across institutions.
Methods: In this prospective research, 146 individuals of both sexes who were referred for examination by CT coronary angiography had either a clinical suspicion of or had surgery for CAD. Complete clinical history collection, physical examination, laboratory testing, coronary CT angiography, and clinical management follow-up were all standard procedures for all research participants.
Results: There was a significant relation between CAD RAD categories and age, hypertension, diabetes mellitus, hyperlipidemia, smoking, right coronary dominant (p<0.05). There was an insignificant relation between CAD RAD categories and sex, body mass index, left coronary dominant and co-dominant.There was a significant association between CAD RAD categories and coronary artery calcium score (P=0.001). There was a significant agreement between CAD- RAD correlation and follow up of patients (p<0.001).
Conclusions: The CAD-RADS score methodology was developed by professional cardiac imaging organizations that strongly advise using it as the standard reporting method for CCTA. It seems that the CAD-RADS scoring and reporting system is a good option for giving our patients a thorough and clinically useful reporting system, which might have a good effect on their treatment and diagnosis.
