160-Slice CT Coronary Angiography
In simple words
A conventional angiogram means threading a catheter through an artery to the heart. A CT coronary angiogram gets much of the same information from an injection in your arm and a scan lasting a few seconds. The scanner freezes the heart between beats and builds a three-dimensional picture of every coronary artery, showing both narrowing and the soft plaque in the vessel wall that has not yet narrowed anything.
Questions this scan answers
- Are the arteries supplying my heart narrowed or blocked?
- Is my chest pain coming from my heart at all?
- Do I actually need an invasive angiogram?
The Prismaa difference
A 0.3-second rotation is what makes this study reliable — it freezes cardiac motion cleanly, and ultra-low-dose reconstruction keeps the radiation well below what these scans traditionally required.
Usually recommended for
- Chest pain where the cause is uncertain
- Intermediate risk of coronary artery disease
- An inconclusive or equivocal treadmill test
- Follow-up after bypass grafts or stents
- Pre-operative cardiac assessment
How to prepare
- Fast for 4 hours. Plain water is allowed.
- Avoid caffeine — tea, coffee, cola, energy drinks — for 12 hours beforehand.
- Bring a recent serum creatinine report; contrast is used.
- Continue your regular heart medication. You may be given a tablet to slow your heart rate before the scan.
- Tell us about asthma, kidney disease, or any previous reaction to contrast dye.
