Coronary Artery Calcium Scoring: Current Status and Future Directions. July-August 2022-Print-Version of the Post-Test

Pdf Summary

The Radiographics Online SA-CME Study Guide for Test 21-0122 focuses on coronary artery calcium (CAC) scoring, discussing its current status and future directions. A key point is that the Agatston score (option c) is the most validated and widely used method for CAC scoring. The CAC score is primarily used to guide statin therapy in patients over 40 years old who are considered at borderline to intermediate risk (5%-20%) of atherosclerotic cardiovascular disease (ASCVD) over a 10-year period.<br /><br />For managing pulmonary nodules found incidentally during CAC scoring CT in patients with a low risk of cardiovascular disease, the 2017 Fleischner Society recommendations suggest that no further workup is needed for a 5-mm nodule.<br /><br />To accurately measure the true short-axis diameter of the thoracic aorta on CAC scoring scans, double-oblique reformatted CT image reconstruction is recommended. This approach ensures precise measurements, avoiding potential inaccuracies from standard reconstructions.<br /><br />For better differentiation of coronary artery stents from calcified plaque on routine CAC scoring CT scans, the continuous linear structure of stents, with an abrupt beginning and end (option d), helps distinguish them from calcified plaque.<br /><br />The guide clarifies that while this document aids in studying for the actual test, SA-CME credit will not be awarded through its submission. To obtain the credit, participants need to take the corresponding online test at the specified resource.<br /><br />This comprehensive guide helps healthcare professionals understand the nuances of CAC scoring, particularly in guiding treatment and decision-making, which is increasingly relevant in managing cardiovascular health.
