How accurate is a CT angiogram of the heart?

What is the difference between CT angiogram and CT angiography?

Benefits and limitations A CT angiogram is a less invasive test than a standard angiogram. A standard angiogram involves threading a thin tube called a catheter through an artery in your arm or leg up to the area being studied. But with a CT angiogram, no tubes are put in your body.

Which is better, Uhr-CT or conventional angiography?
