Question 1

How does CT Coronary Angiography compare to conventional angiography?

Accepted Answer

CT Angiography offers a non-invasive alternative to conventional angiography, reducing the risk of complications, avoiding catheter insertion, and providing rapid, high-resolution images of blood vessels while retaining diagnostic accuracy. 

Question 2

What are the limitations of CT Coronary Angiography?

Accepted Answer

CT Angiography exposes patients to radiation and contrast dye risks and may not adequately visualise very small vessels or assess functional blood flow compared to other advanced imaging modalities. 

Question 3

How do I manage post-test care following CT coronary Angiography?

Accepted Answer

After CT Angiography, patients should maintain hydration to expedite contrast clearance, monitor for any allergic reactions, and follow their doctor’s instructions regarding medication resumption and activity restrictions. 

Question 4

When is CT Angiography preferred over other tests for vascular assessment?

Accepted Answer

CT Angiography is preferred when a rapid, detailed evaluation of vascular anatomy is required, particularly in emergency cases or when non-invasive imaging is needed to assess complex vascular structures.
