Private CT Coronary Angiogram Assessment in London
CT coronary angiography can provide detailed images of the heart arteries when the clinical question is possible coronary disease. The right test depends on your symptoms, risk and previous results.
What CT coronary angiography can answer.
A CT coronary angiogram uses ECG-gated X-ray imaging and contrast injected into a vein to show the coronary arteries. It can help identify coronary plaque and narrowing, or provide reassurance when significant coronary disease is not found.
It is most useful when selected to answer a defined clinical question. Dr Bhuva reviews the symptom pattern, cardiovascular risk, ECG, kidney function, medication, previous tests and the likelihood that the result will change treatment.
When it may be considered
- Stable or recurring chest discomfort where coronary disease is possible
- Breathlessness or reduced exercise tolerance requiring coronary assessment
- An inconclusive or discordant previous cardiac test
- Clarifying coronary anatomy before selected procedures
- Assessing plaque when the result would alter prevention or treatment
From assessment to a useful result.
Before the scan
The indication, previous imaging, renal function, allergies and medication are reviewed. You receive preparation instructions from the imaging provider.
During the scan
ECG leads are attached and intravenous contrast is given. Medication may sometimes be used to optimise heart rate or coronary visibility.
After the scan
The findings are explained in the context of symptoms and risk, with proportionate prevention, medication or further investigation where required.
CT coronary angiogram questions.
What does a CT coronary angiogram show?
A CT coronary angiogram uses X-rays and intravenous contrast to create detailed images of the coronary arteries. It can identify or help exclude coronary plaque and narrowing. The result must be interpreted alongside symptoms, risk factors and previous tests.
Is a CT coronary angiogram suitable for everyone?
No. Suitability depends on the clinical question, heart rhythm, kidney function, contrast allergy, pregnancy and previous test results. A consultation helps determine whether CT coronary angiography or another investigation is more appropriate.
Evidence and review.
The assessment pathway is informed by the NICE guideline on recent-onset chest pain of suspected cardiac origin.
