    Myocardial Perfusion PET Procedure Guideline
    (Galenos Publishing House, 2024) Karaçavuş, Seyhan; Yalçın, Hülya; Özkan, Elgin; Demir, Hakan; Çağlıyan, Feyza; Özdemir, Semra; Tosun, Fevziye Canbaz
    Myocardial perfusion imaging using positron emission tomography (PET) constitutes a non-invasive diagnostic procedure that provides crucial diagnostic and prognostic insights in the context of coronary artery disease. It enables the identification of microvascular circulation disorders in the early phases. The utilization of myocardial PET perfusion studies is on the rise, primarily owing to significant advantages compared to single photon emission tomography. These advantages include superior resolution and sensitivity, robust attenuation correction, reduced radiation exposure, and the capability for absolute quantification of stress and rest myocardial blood flow. This guide endeavors to establish standardized protocols for quantitative myocardial PET perfusion imaging and aims to provide information concerning their clinical applications and interpretation, aligning with international guidelines and relevant literature. © 2024 Galenos Publishing House.

    Procedure Guideline with F-18 FDG PET/CT in Large Vessel Vasculitis
    (Galenos Publishing House, 2024) Ertürk, Seyit Ahmet; Özkan, Elgin; Demir, Hakan; Çağlıyan, Feyza; Özdemir, Semra; Karaçavuş, Seyhan; Yalçın, Hülya
    Large vessel vasculitis is defined as an inflamatuar disease that mainly affects large arteries, with two main variants, Takayasu arteritis and giant cell arteritis (GCA). GCA may be associated with polymyalgia rheumatica (PMR), a rheumatic inflammatory condition characterized by inflammation of periarticular structures. Fluorine-18 (F-18) fluorodeoxyglucose (FDG) positron emisyon tomography (PET)/computed tomography (CT) is a functional imaging technique frequently used in oncology and plays an important role in the field of inflammatory diseases. The aim of this guideline is to assist nuclear medicine physicians in determining indications, patient preparation, imaging methods, evaluation and reporting stages during the evaluation of patients with suspected or diagnosed large vessel vasculitis and/or PMR with F-18 FDG PET/CT. © 2024 Galenos Publishing House.
