Witryna6 maj 2024 · A computerized tomography (CT) coronary angiogram is an imaging test that looks at the arteries that supply blood to the heart. A CT coronary angiogram uses a powerful X-ray machine to produce images of the heart and its blood vessels. The test is used to diagnose a variety of heart conditions. The decision to perform a percutaneous coronary intervention (PCI) is usually based on angiographic results alone. Angiography can be used for the visual evaluation of the inner diameter of a vessel. In ischemic heart disease, deciding which narrowing is the culprit lesion is not always clear-cut. Fractional flow reserve can provide a functional evaluation by measuring the pressure decline caused by a vessel narrowing.
