CT coronary angiography (CCTA)
Detects: Narrowing and soft plaque in the coronary arteries
What it is
A contrast-enhanced CT that produces detailed images of the coronary arteries themselves — showing narrowing and non-calcified (soft) plaque a calcium score can't.
Where & when it’s offered
At advanced imaging centers and cardiology/hospital radiology departments.
Why it’s offered
It's increasingly used to evaluate chest pain and to characterize plaque when more detail is needed than a calcium score provides.
When it’s routine
Typically used for evaluation of symptoms or specific risk questions rather than routine screening. Your provider determines when it's appropriate.
