Multidetector Computed Tomography

Provides a three-dimensional reconstruction of images of the organ under examination

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.

- Coronary CT angiography or Coronary CT
  Angio-TC Cardíaco o TC Cardíaco
  
  The Coronary CT angiography or non-invasive Coronarography is a diagnostic test to examine arteries of the heart, or coronary arteries, using state-of-the-art MDCT equipment and an iodinated contrast agent to obtain two- and three-dimensional images. 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.

Preparation for the test consists of following a low-fibre diet for three days before the test (to cleanse the colon and rectum) and ingesting an iodinated oral contrast agent the day before the test (to mark the stool so that it can be correctly distinguished from any colonic lesions). Unlike fibrocolonoscopy, no sedation or bowel preparation is required. The test is performed in the CT room, where air is blown through a small flexible tube to distend the colon.

- Gold seeding for radiotherapy
  Marcaje semillas oro para radioterapia
  
  An invasive procedure that uses specific needles and equipment to insert a gold marker (measuring just a few millimetres) next to tumour lesions located in internal organs. These particles will subsequently facilitate the application of radiotherapy to the lesions, making it more effective and less harmful to healthy tissue. The procedure is guided by CT fluoroscopy. Local anaesthesia is applied and sedation is occasionally used. The duration of the procedure varies based on the technical difficulty.
