Yes, a CT scan, specifically a CT angiography, can be used to detect clogged arteries, including those in the heart. CT angiography is a non-invasive imaging test that uses X-rays and a contrast dye to visualize the arteries. According to the information provided, CT scans have been effective in detecting blocked arteries with a high degree of accuracy. They detected blocked arteries 85% of the time, and 90% of the arteries that the CT scans identified as blocked actually had blockages. However, it's important to note that there was a 13% misclassification rate, which means that in some cases, the CT scans either falsely identified an artery as blocked or missed a blockage.

As it turned out, 56% of the patients did indeed have angiogram-demonstrated coronary artery disease. And the CT scans worked pretty well. They detected blocked arteries 85% of the time, and 90% of the arteries they said were blocked actually had blockages. On the other hand, the CT scans misclassified 13% of patients.
