Calcium Scoring (CAC)
CT Coronary Angiography
Cardiac CT (Structure)
Coronary Artery Calcium Scoring (CAC) is a fast, non-contrast CT scan that detects and quantifies calcified plaque in the coronary arteries — the same arteries that cause heart attacks. The CAC Score (Agatston Score) is one of the most powerful predictors of future cardiovascular events, independent of traditional risk factors. Recommended annually or every 2 years for high-risk individuals aged 40–75 as a preventive cardiac screening test.
- ✅No contrast injection: Completely non-invasive — no needle, no dye, no fasting. Walk in and scan in 15 minutes.
- ✅Agatston Score: Standardised score correlating directly with coronary plaque burden and 10-year cardiovascular risk
- ✅Reclassifies risk: Frequently upgrades or downgrades cardiovascular risk beyond the Framingham score — changes statin decisions
- ✅Annual screening: Tracks plaque progression year-over-year — motivates lifestyle and medication adherence
- ✅Fast & affordable: 15-minute scan, lowest-cost cardiac CT — ideal first step in preventive cardiac workup
CT Coronary Angiography (CTCA) is the non-invasive gold standard for imaging the coronary arteries — providing detailed 3D visualisation of the left main, left anterior descending (LAD), left circumflex (LCx), and right coronary artery (RCA). It detects and characterises coronary plaque (calcified, mixed, soft), stenosis severity, and vessel anatomy — answering "Do I have coronary artery disease?" without catheterisation. For patients with intermediate or uncertain cardiac symptoms, CTCA is now the first-line investigation.
- ✅All four coronary arteries: LM, LAD (and diagonals), LCx (and obtuse marginals), RCA (and PDA, PLV) — complete anatomy
- ✅Plaque characterisation: Calcified vs soft (vulnerable) plaque — soft plaque has higher rupture risk despite lesser stenosis
- ✅Stenosis grading: 0% (none) to 100% (total occlusion) — determines need for stress test, catheterisation, or surgery
- ✅Non-invasive vs conventional angiography: No catheter, no arterial puncture, no hospitalisation — outpatient procedure in 30–45 minutes
- ✅High negative predictive value: Normal CTCA reliably rules out significant coronary artery disease — avoids unnecessary invasive angiograms
Structural Cardiac CT uses contrast-enhanced CT to evaluate the cardiac chambers, valves, pericardium, great vessels, and cardiac masses — without ECG gating limitations. It is the primary investigation for pre-TAVR/TAVI planning, evaluation of cardiac masses and thrombi, pericardial disease, congenital heart disease anatomy, and pulmonary vein mapping before catheter ablation for atrial fibrillation.
- ✅Pre-TAVR planning: Aortic annulus sizing, valve anatomy, access route planning — essential before transcatheter valve replacement
- ✅Left atrial appendage (LAA) imaging: Thrombus detection before cardioversion or ablation — safer than transesophageal echo in many cases
- ✅Pericardial disease: Pericardial thickness, calcification, effusion characterisation — for constrictive pericarditis diagnosis
- ✅Cardiac masses: Myxoma, lipoma, thrombus, metastasis — CT characterises tissue and origin
- ✅Congenital heart disease: Complex anatomy, shunts, vascular connections for pre-surgical planning in adults and children

What is a CT Cardiac Scan?
A fast, non-invasive CT investigation of the heart and coronary arteries — no catheter, no hospitalisation, same-day results.
What CT Cardiac Examines
CT Cardiac studies visualise the coronary arteries (LM, LAD, LCx, RCA and all major branches), coronary calcification burden, cardiac chambers and function (ejection fraction on gated studies), cardiac valves, pericardium, aortic root, pulmonary arteries, and left atrial appendage. Calcium scoring specifically quantifies calcified plaque in each artery. CTCA additionally provides contrast-enhanced lumenography showing all stenoses and plaque types.
How ECG-Gated CT Works
The heart beats 60–90 times per minute — standard CT imaging would be motion-blurred. ECG-gating synchronises CT acquisition to the cardiac cycle, capturing images during the rest phase (usually 70–80% of the R-R interval) when the heart moves least. Our 160-Slice CT acquires the entire heart in a single heartbeat — under 5 seconds. This temporal resolution is critical for coronary artery sharpness at high heart rates.
CT Cardiac vs Invasive Angiography
Conventional cardiac catheterisation involves inserting a catheter into a coronary artery via the groin or wrist — carries 0.5–1% complication risk, requires hospitalisation, and costs significantly more. CTCA provides equivalent diagnostic information for stenosis detection non-invasively, with >95% negative predictive value. Current ACC/AHA guidelines recommend CTCA as first-line for stable chest pain evaluation, replacing invasive angiography for diagnostic purposes in most patients.
Heart Rate & Beta-Blockers
Image quality for CTCA is optimal at heart rates below 65 bpm. For patients with higher heart rates, a beta-blocker (metoprolol) is given orally 1–2 hours before the scan to slow the heart. This is a standard, safe, and effective protocol. Patients on existing beta-blockers should continue taking them. Sublingual nitroglycerin is also given just before scanning to dilate the coronary arteries and improve visualisation.
The Cardiac Structures CT Scans
Comprehensive imaging of every cardiac structure — from coronary arteries to pericardium.
Left Coronary System
The left coronary artery supplies 70% of the heart muscle — critical for anterior and lateral wall perfusion.
- Left Main (LM) stenosis — the most dangerous lesion
- LAD (Left Anterior Descending) — all segments D1 to D3
- LCx (Left Circumflex) — OM1, OM2 branches
- Soft plaque at bifurcation points
- Myocardial bridging of LAD
- Coronary anomalies and variants
Right Coronary System
The right coronary artery supplies the inferior heart wall, SA node, and AV node.
- RCA proximal, mid, and distal segments
- PDA (Posterior Descending Artery)
- PLV (Posterior Left Ventricular) branches
- Dominance assessment (right vs left dominant)
- RCA total occlusion detection
- Stent patency and in-stent restenosis
Cardiac Chambers & Function
Gated CT provides functional cardiac information beyond just coronary anatomy.
- Left ventricular (LV) ejection fraction
- LV wall motion assessment
- LV and RV volumes (end-systolic, end-diastolic)
- Left atrial size and appendage thrombus
- Cardiac mass detection (myxoma, thrombus)
- Interventricular septal defect
Aortic Root & Valves
The aortic root and cardiac valves — critical for pre-TAVR planning and valvular disease assessment.
- Aortic root dimensions (annulus, sinus, STJ)
- Aortic valve morphology (bicuspid vs tricuspid)
- Aortic valve calcification scoring
- Pre-TAVR annulus sizing and access
- Mitral valve annulus dimensions
- Pulmonary valve assessment
Pericardium
The heart sac — evaluated for thickening, calcification, effusion, and constriction.
- Pericardial thickening (>4mm — constriction)
- Pericardial calcification
- Pericardial effusion characterisation
- Constrictive pericarditis assessment
- Pericardial cysts and tumours
- Post-surgical pericardial changes
Pulmonary Veins & Great Vessels
The thoracic vessels around the heart — essential for ablation planning and vascular disease.
- Pulmonary vein mapping (4 veins) pre-AF ablation
- Pulmonary vein stenosis post-ablation
- Aortic aneurysm and dissection
- Pulmonary artery assessment
- LIMA/RIMA graft patency (post-CABG)
- Coronary bypass graft evaluation
Types of CT Cardiac Scans Available
We offer the complete range of cardiac CT protocols — from simple calcium scoring to complex pre-surgical TAVR planning.
Calcium Scoring (CAC)
Non-contrast ECG-gated CT quantifying calcified coronary plaque — Agatston Score for 10-year cardiovascular risk assessment. No fasting, no injection, 15 minutes. Ideal for preventive cardiac screening aged 40–75.
CT Coronary Angiography (CTCA)
Contrast-enhanced ECG-gated CT of all coronary arteries — vessel-by-vessel stenosis grading, plaque type, and coronary anatomy. Replaces diagnostic invasive angiography in most stable chest pain patients.
Cardiac CT (Structure)
Contrast CT of cardiac chambers, valves, and great vessels — for pre-TAVR annulus sizing, LAA thrombus, pericardial disease, cardiac masses, and congenital heart disease anatomical evaluation.
CTCA + Calcium Scoring Combined
The most comprehensive cardiac CT — calcium scoring followed immediately by CTCA in a single session. Provides both plaque burden (Agatston Score) and coronary anatomy (stenosis mapping) — the complete coronary picture.
CT Bypass Graft Assessment
Post-CABG CTCA evaluating internal mammary artery (LIMA/RIMA) and saphenous vein graft patency — determining graft occlusion or stenosis causing recurrent symptoms after bypass surgery. Non-invasive and definitive.
Pulmonary Vein CT (Pre-Ablation)
Pre-catheter ablation CT mapping of pulmonary vein anatomy and left atrial dimensions — essential for electrophysiologists planning pulmonary vein isolation for atrial fibrillation. Also detects LAA thrombus prior to ablation.

Benefits of CT Cardiac Scan
Why CT Cardiac is transforming coronary artery disease diagnosis — non-invasive, fast, and definitive.
Non-Invasive — No Catheter
CT Cardiac completely replaces diagnostic invasive catheterisation for most patients — no arterial puncture, no hospitalisation, no catheter-related complications. An outpatient procedure home the same day.
Detect Disease Before Symptoms
CAC Scoring detects silent coronary plaque years before symptoms or a heart attack — enabling preventive treatment (statins, aspirin, lifestyle) at the optimum time to prevent irreversible cardiac damage.
Plaque Type Matters
CTCA distinguishes soft (vulnerable) plaque from calcified (stable) plaque — soft plaque with less stenosis can still rupture and cause heart attacks. This tissue characterisation is not possible with catheter angiography alone.
Avoids Unnecessary Invasive Tests
A normal CTCA has >98% negative predictive value — ruling out significant coronary artery disease definitively. This prevents thousands of patients from undergoing unnecessary invasive cardiac catheterisation every year.
How to Prepare for CT Cardiac Scan
Preparation depends on your protocol — CAC needs almost nothing, while CTCA needs fasting and heart rate control. Follow these guidelines carefully.
Do's – Before Your CT Cardiac Scan
- ✓Arrive 30 minutes early — CTCA needs IV placement and heart rate assessment before scanning
- ✓Bring your cardiologist's prescription, ECG reports, and any previous cardiac workup
- ✓Continue your heart medications as prescribed — especially beta-blockers (lowers heart rate for better CT quality)
- ✓For CTCA: fast for 4–6 hours (no food or milk; clear water allowed)
- ✓Inform staff about allergy to contrast dye, kidney disease, or previous contrast reactions
- ✓Tell us about pacemakers, defibrillators, or any cardiac implants — CT is safe with all hardware
- ✓Practise deep breathing and breath-holding — you will be asked to hold for 8–10 seconds during the scan
- ✓Wear loose, comfortable clothing — no metal zippers or buttons on the chest
Don'ts – What to Avoid
- ✗Do NOT stop beta-blockers before CTCA — maintaining low heart rate is critical for image quality
- ✗Avoid caffeine (coffee, tea, energy drinks) for 12 hours before CTCA — caffeine raises heart rate
- ✗Do not eat 4–6 hours before CTCA or Structural Cardiac CT — not required for CAC Scoring
- ✗Do NOT take Metformin 48 hours before and after contrast CT (consult your doctor)
- ✗Avoid strenuous exercise on the day of CTCA — can raise heart rate and affect image quality
- ✗Do not hide contrast allergy or kidney disease — serious allergic reactions can occur with contrast
- ✗Avoid breastfeeding 24–48 hours after contrast injection (pump and discard)
- ✗Do NOT drive immediately after if sedation or beta-blocker has been given — wait at centre for 30 minutes
What Happens During
Your CT Cardiac Scan?
A well-structured 30–45 minute process for CTCA — from heart rate optimisation to coronary artery visualisation.
Registration & Cardiac Safety Check
Present your prescription. Staff measures your resting heart rate. If >65 bpm for CTCA, oral metoprolol is given 1–2 hours before scanning. IV cannula is placed for contrast and nitroglycerin administration.
ECG Lead Placement
Six ECG leads are attached to your chest — these monitor your heart rhythm in real-time and trigger the CT scanner to acquire images at the optimal phase of the cardiac cycle. No X-ray or electrical current is passed through you.
Pre-Scan Nitroglycerin (For CTCA)
Sublingual nitroglycerin spray is given 1–2 minutes before CTCA scanning — it temporarily dilates the coronary arteries, improving contrast filling and visual clarity. You may feel a brief headache; this is normal and harmless.
The Scan (5–15 Seconds Breath-Hold)
Contrast is injected via IV (for CTCA). You hold your breath for 8–10 seconds while the scanner rotates — the entire heart is captured in a single heartbeat. You feel warmth spreading through your body during contrast injection — completely normal.
Same-Day Cardiologist Report
Our cardiologist-radiologist generates 3D coronary reconstructions, grades each coronary segment for stenosis and plaque, calculates Agatston Score, and prepares a structured report — delivered same day via WhatsApp and email.
Heart Rate Control Is Everything for CTCA
The single most important factor determining CTCA image quality is your heart rate. At rates above 70 bpm, motion blur degrades coronary artery sharpness — especially the right coronary artery which moves fastest. Oral metoprolol (25–50mg) is given 1–2 hours before your scan to bring your heart rate below 65 bpm. This is safe for most patients. If you are on existing beta-blockers, take your usual dose on the morning of the scan. Inform our staff about asthma or bradycardia when booking.
When CTCA Is Not Recommended
CTCA may not be suitable for: (1) Patients with very high heart rates that cannot be controlled; (2) Patients with known severe contrast allergy (pre-medication required); (3) Significant kidney impairment (eGFR <30); (4) Extensive prior coronary stenting (stent artefact limits assessment); (5) Active chest pain or haemodynamic instability (invasive angiography is preferred). Consult your cardiologist if any of these apply — our team will advise the most appropriate cardiac imaging for your situation.
