CT Angiography

Contrast-enhanced CT angiography of vascular territories (aorta, carotid, cerebral, peripheral, pulmonary) on Siemens Dual Source 2×128-slice CT. Pozitron Medical's cardiac-grade scanner delivers precise vascular imaging with sub-millimetre resolution.

CT angiography (CTA) at Pozitron Medical Budapest uses the Siemens Somatom Drive Dual Source CT to produce high-resolution, contrast-enhanced maps of the vascular system. The Dual Source configuration — two independent tube-detector pairs rotating at high speed — delivers the sub-second gantry rotation times needed for sharp arterial opacification windows, particularly important for cardiac and aortic studies where motion would otherwise degrade image quality. CTA is performed across all major vascular territories: the thoracic aorta and its branches, the abdominal aorta, iliac vessels and lower extremity arteries, carotid arteries from the aortic arch to the circle of Willis, pulmonary arteries (CTPA for suspected embolism), and the coronary arteries (covered under the dedicated Cardio-CT service at 170,000 HUF). The technique involves a bolus injection of iodinated contrast timed to reach peak arterial opacification during the CT acquisition, producing bright lumenal signals against the surrounding structures. Aortic CTA is used for surveillance and characterisation of abdominal and thoracic aortic aneurysm — monitoring known aneurysms for expansion that would trigger intervention threshold, or for acute presentation with suspected dissection where CT is the definitive emergency investigation. Carotid CTA quantifies stenosis at the carotid bifurcation and internal carotid origin, the most common site of cerebrovascular embolic risk in atherosclerosis. Findings directly guide the surgical and endovascular intervention threshold for carotid endarterectomy or stenting. Cerebral CTA covers the intracranial arterial circulation for aneurysm, arteriovenous malformation, or vasospasm assessment. Pulmonary CT angiography (CTPA) is the definitive investigation for acute pulmonary embolism. The protocol uses a contrast injection protocol specifically timed to opacify the pulmonary arteries, allowing detection of clot from the main pulmonary trunk down to segmental vessel level. Diagnosis of pulmonary embolism on CTPA triggers immediate anticoagulation and determines risk stratification for potential thrombolysis. The examination requires renal function screening (serum creatinine) for patients with known kidney disease, contrast allergy assessment, and IV cannulation. Total appointment duration varies by territory: pulmonary CTA is approximately 30 minutes; aortic or peripheral studies are 45–60 minutes. Reports are issued by specialist radiologists within 3–5 working days. Booking at medicall.cc or +36 1 505-8888. No referral required for self-pay.
