Coronary CT Angiography

Non-invasive contrast-enhanced CT of the coronary arteries using a dual-source Siemens Somatom Flash scanner with ECG gating and SAPHIRE low-dose reconstruction. Detects stenosis, plaque, and coronary anomalies without catheterisation. Estimated price: €380–450.

Coronary CT angiography (CCTA) at Na Homolce Hospital uses the hospital's dual-source Siemens Somatom Flash scanner — one of the most capable platforms available for cardiac imaging — to produce high-resolution, three-dimensional images of the coronary arteries. The dual-source configuration and SAPHIRE reconstruction system allow significant radiation dose reduction compared to earlier-generation CT equipment while maintaining diagnostic image quality. The examination targets the left main coronary artery, left anterior descending artery (LAD), left circumflex artery (LCx), and right coronary artery (RCA), producing a detailed map of plaque burden, lumen narrowing, and coronary anomalies. ECG gating synchronises image acquisition with the cardiac cycle to eliminate motion blur of the rapidly moving coronary vessels. Intravenous iodinated contrast is injected at a precisely timed rate to opacify the coronary lumen during acquisition. Na Homolce Hospital's radiology department has explicitly documented performing "a significant number of CT scans of the heart, including CT coronarographies," and the hospital's Cardiology Clinic — a joint department with Charles University since 2025 — performs 3,500 catheterisation procedures annually. This depth of cardiovascular expertise directly informs the multidisciplinary review and interpretation of cardiac CT findings. Coronary CT angiography has a very high negative predictive value. A normal or near-normal CCTA result effectively excludes significant obstructive coronary artery disease in patients with stable chest pain, atypical cardiac symptoms, or intermediate pre-test probability. European Society of Cardiology guidelines recommend CCTA as a first-line investigation for stable chest pain in patients with low-to-intermediate likelihood of coronary artery disease, reducing the number of patients who require invasive catheter angiography to confirm normal coronary anatomy. The Foreign Patients department ([email protected], +420 257 273 289) coordinates international self-pay appointments, including pre-examination preparation guidance, contrast allergy screening, and, where clinically indicated, beta-blocker preparation to optimise heart rate for imaging. Reports are prepared by specialist radiologists with cardiovascular imaging expertise and delivered in written form with per-segment stenosis grading. Na Homolce Hospital holds JCI (Joint Commission International) accreditation — the gold standard for hospital quality assurance — and carries a Comprehensive Cardiovascular Centre designation from Czech health authorities. These certifications mean cardiac imaging takes place within a clinical governance framework validated by independent international auditors.
