Launch of CT Coronary Angiography at Euromedica Dytiki Thessaloniki
The Diagnostic Center Euromedica Dytiki Thessalonikiis one of the most well-known diagnostic centers of the Euromedica Group. As part of the continuous upgrade of its cardiology services, it has introduced the new service of CT Coronary Angiography (CTCA), an advanced, non-invasive imaging examination that enables detailed evaluation of the coronary arteries. The addition of this examination enhances the center’s range of cardiological diagnostic capabilities, offering high accuracy, speed, and safety.
What is CT Coronary Angiography?
CT Coronary Angiography (CTCA) is a specialized computed tomography scan that visualizes the coronary arteries—the vessels that supply blood to the heart. Using modern multi-slice CT scanners and a special contrast agent, the method allows for:
Assessment of the presence and extent of atherosclerotic plaque
Detection of coronary artery stenosis
Evaluation of cardiovascular risk
Detailed visualization of arterial anatomy with high-resolution imaging
It is a highly accurate diagnostic technique that significantly contributes to the early detection of coronary artery disease and comprehensive cardiovascular assessment.
How the Examination is Performed
Patient Preparation: The patient enters the examination room after being informed about the procedure. Vital signs are measured and, if necessary, medication may be administered to stabilize the heart rate.
Contrast Administration: An iodine-based contrast agent is administered through an intravenous line to enhance visualization of the coronary vessels.
Imaging Procedure: The patient lies on the CT scanner table, and high-resolution images synchronized with the heartbeat are acquired using a specialized protocol.
Image Processing: The images are reconstructed into three-dimensional representations, allowing detailed evaluation of the coronary arteries.
The examination is characterized by a high level of safety, is painless and non-invasive, and does not require recovery time.

When is it Recommended?
CT Coronary Angiography is scientifically indicated in the following cases:
Patients with chest pain or symptoms suggestive of coronary artery disease
Individuals with intermediate cardiovascular risk (neither low nor high)
Preventive screening in individuals with a family history of heart disease
Investigation of inconclusive findings from other tests (e.g., stress test, myocardial perfusion scan)
Preoperative assessment before certain non-cardiac surgeries
Follow-up of patients with known coronary artery disease without the need for invasive coronary angiography
The method is an ideal choice when safe and reliable evaluation is required without hospitalization.
Each cardiovascular scan performed on the CT scanner lasts only a few seconds. The entire process—including preparation, examination, and patient briefing—typically takes between 30 and 60 minutes, depending on the case.
Patient Preparation Before the Examination
Proper preparation is an important factor for optimal image quality and safe performance of CT Coronary Angiography. Patients should follow these instructions:
Avoid caffeine for 12–24 hours before the examination: Caffeine affects heart rate and may reduce the effectiveness of medications administered for heart rate control.
Avoid smoking for at least 4 hours before the examination: Smoking increases heart rate.
Light meal or fasting for 3–4 hours: Heavy meals may cause discomfort during the examination.
Hydration: Drinking water is recommended unless otherwise instructed by the physician.
Inform the medical team about allergies or previous reactions to contrast agents: This is essential for taking preventive measures.
Continue prescribed cardiac or other medications unless otherwise advised: Patients should not modify their medication without medical guidance.
Remove metallic objects: Jewelry and metal items should be removed to avoid imaging artifacts.
The introduction of CT Coronary Angiography at Euromedica Dytiki Thessaloniki provides a significant diagnostic tool for the prevention and early management of coronary artery disease. The implementation of this examination reflects the center’s commitment to strict scientific standards, certified procedures, and continuous technological advancement.
Equipped with a state-of-the-art CT scanner ideal for cardiac imaging and staffed by specialized medical and paramedical personnel experienced in coronary imaging, the center serves as a reference point for comprehensive and safe cardiological assessment.
