CT Coronary Angiography is an imaging method performed using a Computed Tomography (CT) scanner with contrast material injected into a vein—without using a catheter, unlike traditional catheter angiography.
Advantages:
- Non-invasive, as no catheter is used.
- Faster – typically takes only 10–15 minutes.
- Provides a three-dimensional image of the heart vessels.
- Often preferred as a first diagnostic method in low-risk patients.
However, CT Coronary Angiography is not suitable for everyone. In patients with irregular heart rhythms, obesity, or advanced vascular calcification, clear images may not be possible. In such cases, traditional angiography is preferred.
Differences Between Catheter Angiography and CT Coronary Angiography
Feature Catheter Angiography CT Coronary Angiography
| Invasive? | Yes | No
| Catheter Use | Yes | No
| Duration | 2–4 hours | 10–15 minutes
| Imaging Method | X-ray | CT (Computed Tomography)
| Stent/Balloon Application | Yes (if needed) | No
When Is Angiography Necessary?
- After a heart attack
- With a family history of early heart disease
- For those experiencing persistent chest pain
- When an exercise stress test shows suspicious results
- For post-bypass or post-stent check-ups
Your doctor will recommend this procedure based on the severity of your condition, your symptoms, and your previous test results. Thanks to CT Coronary Angiography, potential blockages can be detected early on the path to your heart.
Remember: Heart health should never be neglected.
Stay up to date with regular check-ups, take symptoms seriously, and take action in time.
