Abstract
Physicians who are in charge with interpretation of fluorine-18 fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) images should be familiar with the imaging artifacts which occur frequently, due to technical reasons. The most common and important ones are attenuation correction artifacts, artifacts due to high-density materials such as metallic implants or concentrated contrast material, respiratory motion artifacts and truncation artifacts. Each artifact can be eliminated or minimized by taking certain measures regarding the FDG PET/CT applications or preparing the patient properly.

Abstract
[18F]-2-floro-2-deoksi-D-glukoz (FDG) pozitron emisyon tomografisi (PET)/bilgisayarlı tomografi (BT) görüntülerini yorumlayan hekimlerin, teknik nedenlere bağlı sıkça ortaya çıkan görüntüleme artefaktlarını tanımaları gerekir. En sık görülenleri ve en önemlileri atenüasyon düzeltme artefaktları, metalik implantlar veya yoğun kontrast maddeler gibi yüksek dansiteli materyallere bağlı artefaktlar, solunum hareket artefaktları ve trunkasyon (kesme, budama) artefaktlarıdır. Her bir artefakt FDG PET/BT uygulamaları ile ilgili önlemler alınarak veya hasta doğru şekilde hazırlanarak ortadan kaldırılabilir veya asgariye indirilebilir.
