Bilgisayarlı tomografi koroner anjiyografinin klinik uygulamaları

Koroner arter hastalıkları Batı toplumlarında ölüme neden olan hastalıkların bir numaralı sebebidir. Koroner arter hastalıklarının değerlendirilmesinde altın standart konvansiyonel anjiyografidir. Ancak, yöntemin invaziv olması ve nadir olmakla birlikte ciddi komplikasyonlara neden olabilmesi, invaziv olmayan, etkin ve güvenilir alternatif bir tanısal yöntemin geliştirilmesini gerekli kılmaktadır. Çokkesitli bilgisayarlı tomografi (BT) sistemlerinin gelişmesi ile birlikte, koroner anjiyografi BT en yaygın uygulama alanlarından biri haline gelmiştir. Teknik gelişmelere rağmen henüz konvansiyonel anjiyografinin çözünürlüğüne ulaşılamamış olmasına karşın, koroner anjiyografi BT’de koroner arter hastalıklarının tanı ve değerlendirilmesinde çok kısa sürede önemli mesafeler kaydedilmiştir. Bu derlemede, son yıllarda hızla gelişen ve kullanımı yaygınlaşan BT koroner anjiyografinin klinik uygulama alanları gözden geçirildi.

Clinical applications of computed tomography coronary angiography

Coronary artery disease is the leading cause of death in western societies. The gold standard for the evaluation and diagnosis of coronary artery diseases is conventional angiography. However, its invasive nature and its potential risks for some rare but serious complications make it necessary to develop an alternative non-invasive diagnostic modality. Since the introduction of multidetector-row computed tomography (CT) systems, cardiac examinations have become one of the most popular applications of CT. Despite technical developments in CT, conventional angiography still remains superior with regard to improved temporal and spatial resolution; nonetheless, recent rapid achievements made in CT technology have considerably broadened diagnostic CT applications in coronary artery diseases. This article reviews the clinical applications of CT coronary angiography that have gained rapid and increasing utility in recent years.
