CT Angiography (CT Angio) is an advanced, non-invasive imaging technique used to visualise blood vessels throughout the body with high precision. It combines computed tomography (CT) scanning with intravenous contrast injection to produce detailed images of arteries and veins. CT Angio plays a crucial role in the diagnosis, evaluation, and management of a wide range of vascular and cardiovascular conditions.

CT Angio is commonly used to assess the coronary arteries, cerebral vessels, carotid arteries, pulmonary arteries, aorta, renal arteries, and peripheral blood vessels. It is instrumental in detecting conditions such as arterial blockages, aneurysms, dissections, vascular malformations, pulmonary embolism, and peripheral arterial disease. The high-resolution images allow clinicians to accurately evaluate vessel anatomy, blood flow, and the extent of disease.

Modern multi-slice CT scanners, including 64 and 128-slice systems, enable rapid image acquisition, reducing scan time and motion artefacts. This is particularly important in cardiac and emergency imaging, where speed and accuracy are critical. Advanced post-processing techniques such as 3D reconstruction, maximum intensity projection, and volume rendering provide comprehensive visualisation for precise diagnosis and treatment planning.

The CT Angio procedure is minimally invasive and typically completed within a short duration. Contrast material is administered intravenously under careful monitoring to enhance vascular visualisation. Patient preparation includes screening for kidney function and contrast allergies to ensure safety. Radiation exposure is minimised through optimised scanning protocols and dose-reduction technologies.

CT Angio services support multiple specialities, including cardiology, neurology, vascular surgery, and emergency medicine. By providing fast, accurate, and detailed vascular assessment, CT Angiography helps guide clinical decisions, plan interventions, and improve patient outcomes in both acute and chronic vascular conditions.
