What is Cardiac CT Angiography?
Cardiac CT Angiography (CCTA) is a non-invasive imaging technique that uses advanced computed tomography to visualize the coronary arteries and assess blood flow. It provides physicians with detailed information about potential blockages and coronary artery disease without requiring cardiac catheterization.
How Does CCTA Work?
During a CCTA scan, a contrast dye is injected into your bloodstream as the CT scanner captures rapid images of your heart and coronary arteries. Our 128-slice CT scanner can acquire these images in just a few seconds, creating detailed 3D reconstructions of your coronary anatomy.
Advantages of CCTA:
- ✓ Non-invasive: No catheterization required
- ✓ Fast and Efficient: Scan takes only seconds
- ✓ High Sensitivity: Can detect even small blockages
- ✓ 3D Visualization: Detailed coronary anatomy assessment
- ✓ Lower Risk: Minimal complications compared to invasive procedures
- ✓ Cost-Effective: Less expensive than cardiac catheterization
Clinical Applications
CCTA is particularly valuable for patients with chest pain, shortness of breath, or risk factors for coronary artery disease. It helps cardiologists determine whether cardiac catheterization is necessary and guides treatment decisions.
Preparation and Procedure
Patients may need to fast for a few hours before the scan and should avoid caffeine to ensure a steady heart rate. Beta-blockers or other heart rate-controlling medications may be administered to optimize image quality. The actual scanning process is painless and takes only minutes.
Understanding Your Results
Results are typically available within 24-48 hours and are interpreted by our experienced radiologists. A detailed report with findings and recommendations is provided to your referring physician and can help guide further cardiac care decisions.
