Summary

This study tests advanced CT scans to find dangerous blockages in heart arteries without needing to insert a tube into the heart. About 142 adults with moderate blockages will get two types of CT scans, and results will be compared to the standard invasive test. The goal is to see if these new scans can accurately identify which blockages need treatment, reducing unnecessary procedures.
