- high diagnostic accuracy, often equivalent to the gold standard of ICA.
-
- requires thin detector collimation (detector width of 0.625 or less), thin slice reconstruction (image thickness ≤1.0 mm)
- cardiac gating (often requiring
- beta blockers for ideal heart rate).
- Coronary CTA provides unparalleled spatial resolution compared to other non-invasive modalities.
