CT Angiography

Contrast-enhanced CT angiography at SurGal Clinic Brno for vascular mapping of carotid arteries, cerebral vessels, aorta, pulmonary vasculature, or peripheral arteries. AIDR low-dose CT with specialist radiology reporting.

CT angiography (CTA) at SurGal Clinic Brno uses precisely timed intravenous contrast injection combined with the clinic's multi-slice CT scanner to produce detailed three-dimensional maps of the vascular anatomy within the target territory. The technique is established as the primary non-invasive investigation for most vascular pathologies, replacing catheter-based conventional angiography for diagnostic purposes in the majority of clinical scenarios. The SurGal radiology department — operating within a comprehensive hospital environment — offers CT angiography of all major vascular territories: carotid arteries (neck vasculature supplying the brain), intracranial cerebral vessels (circle of Willis and its branches), thoracic aorta, abdominal aorta, renal arteries, pulmonary vasculature (for suspected pulmonary embolism — CTPA), and peripheral arteries of the lower limbs. The specific protocol — including contrast timing, scan delay, and coverage — is tailored to the target territory by the radiology team. For pulmonary embolism CT angiography (CTPA), the protocol is optimised to opacify the pulmonary arterial tree from the main pulmonary arteries down to the segmental level, enabling direct visualisation of intraluminal thrombus. This is the primary investigation for suspected pulmonary embolism, a potentially life-threatening condition where rapid accurate diagnosis is critical. CT angiography of the carotid and cerebral vessels provides non-invasive assessment of stenosis, occlusion, aneurysm, arteriovenous malformation, and dissection — conditions that are clinically important in stroke prevention and acute stroke workup. Aortic CTA is the standard investigation for aortic aneurysm, dissection, and pre-operative planning before endovascular repair. The AIDR dose-reduction software at SurGal keeps radiation exposure substantially lower than conventional CT while maintaining the image quality required for accurate vascular diagnosis. Reports are prepared by specialist radiologists and include three-dimensional maximum intensity projection (MIP) reconstructions and multiplanar reformats that allow comprehensive vascular assessment.
