Abstract
in English, Turkish

The purpose of this article is to provide an up to date review on the spectrum of applications of perfusion computed tomography (CT) in the abdomen. New imaging techniques have been developed with the objective of obtaining a structural and functional analysis of different organs. Recently, perfusion CT has aroused the interest of many researchers who are studying the applicability of imaging modalities in the evaluation of abdominal organs and diseases. Per-fusion CT enables fast, non-invasive imaging of the tumor vascular physiology. Moreover, it can act as an in vivo biomarker of tumor-related angiogenesis.

Bu çalışmanın amacı batında perfüzyon bilgisayarlı tomografi (BT) uygulama spektrumuna çağdaş bir yaklaşım sağlamaktır. Yeni görüntüleme teknikleri sadece organların yapısını değerlendirmek için değil aynı zamanda farklı organların fonksiyonel analizlerini yapmak için de geliştirildi. Son zamanlarda, geliştirilen bu cihazlar arasında perfüzyon BT abdominal organların ve hastalıkların değerlendirilmesinde bu gibi görüntüleme modalitelerinin uygulanabilirliğinde çoğu araştırmacının ilgisini çekti. Perfüzyon BT tümörün vasküler fizyolojisini tanımlama olanağı sağlar. O non-invazivdir ve onun uygulaması ve analizi kolaydır. Dahası, O tümör ilişkili anjiogenezin in-vivo biyolojik belirleyicisi olarak davranabilir.

Keywords: Abdominal perfusion; Computed tomography.
