Multidetector Computed Tomography
Centro Médico Teknon uses state-of-the-art technology to render three-dimensional reconstruction of the organ under examination. Computed Tomography uses a rotational movement to send successive X-ray emissions to one or more detectors. This data is integrated into a single system which exports it in a ‘volume’ of images representing the scanned region. This provides detailed images with a density resolution far superior to that of conventional radiology.

Multidetector computed tomography (MDCT) entails high-speed imaging that is beneficial in assessing coronary arteries with high anatomical precision, particularly in evaluating narrowing or stenosis, calcifications, anatomical variants, etc., as its speed prevents the artefact caused by the constant movement of the heart (1,000 images can be obtained in less than 10 seconds). The information obtained requires processing at workstations equipped with specialised software capable of reconstructing the coronary arteries, thereby enabling an assessment to be made of the number, location and characteristics of the lesions. All this information is obtained non-invasively, involving a simple puncture of a peripheral vein (in the arm). To ensure the heart rate stays below 75 bpm, some patients will need preliminary treatment with beta blockers.
