Comparison of 18F FDG PET / CT, MRI (DWI + DCE) and MRI + 18F FDG PET/CT in the detection of axillary metastatic lymph nodes in patients with newly diagnosed breast cancer
Gündoğdu, Hasan; Kupik, Osman (2021)Aim: We visually and quantitatively investigated the success of using 2-deoxy-2-[fluorine-18] fluoro-Dglucose integrated with computed tomography ( 18F-FDG PET/CT) and magnetic resonance imaging (MRI) [Dynamic contrast ... -
Comparison of clinical and PET-derived prognostic factors in patients with non-Hodgkin lymphoma: a special emphasis on bone marrow involvement
Kupik, Osman; Akın, Serkan; Tuncel, Murat; Eren, Gülnihan; Türker, Alev; Kars, Ayşe; Erbaş, Belkıs (Lippincott Williams & Wilkins, 2020)Objective in patients with non-Hodgkin lymphoma (NHL), we investigated F-18 FDG PET/computed tomography (CT) parameters, clinical findings, laboratory parameters, and bone marrow involvement (BMI) status for predictive ... -
Comparison of computed tomography, magnetic resonance imaging and positron emission tomography in detecting cartilage invasıon in larynx cancers
Birinci, Mehmet; Beyazal Çeliker, Fatma; Yemiş, Tuğba; Kupik, Osman; Terzi, Suat; Bedir, Recep; Özergin, Zerrin; Dursun, Engin; Erdivanlı, Özlem Çelebi (2023)Objective: Laryngeal cancer is the most common malignancy of the head and neck region, following skin tumors. Cartilage invasion is an important feature in staging of laryngeal cancers. This study compared three frequently ... -
A comparison study of dual-energy spectral CT and 18F-FDG PET/CT in primary tumors and lymph nodes of lung cancer
Kupik, Osman; Metin, Yavuz; Eren, Gülnihan; Metin, Nurgül Orhan; Arpa, Medeni (Turkish Society of Radiology, 2021)PURPOSE We aimed to investigate whether there is a correlation between dual-energy spectral computed tomography (DESCT) and 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) parameters ... -
Do volume-based and metabolic 18F FDG PET/CT parameters identify groups at risk for poor prognosis in patients with newly diagnosed metastatic and non-metastatic non-small cell lung cancer?
Kupik, Osman; Bozkurt, Mehmet; Asa, Sertaç; Eren, Gülnihan; Gündoğdu, Hasan; Arpa, Medeni (Akad Doktorlar Yayinevi, 2020)To determine the relationship between F-18 FDG PET/CT parameters of the primary tumor/nodal metastasis/distant metastasis and overall survival (OS) of patients with newly diagnosed non-small cell lung cancer (NSCLC). Data ... -
FDG PET/CT in peritoneal metastasis from prostate cancer
Güngör, Serkan; Asa, Sertaç; Kupik, Osman (Lippincott Williams & Wilkins, 2016)Prostate cancer is one of the leading causes of cancer death in men. the prognosis in prostate cancer is greatly worsened by the presence of metastases, which are most commonly found in bone, lung, liver, and brain. the ... -
Necrosis on pre-radiotherapy F-18-FDG PET/CT is a predictor for complete metabolic response in patients with non-small cell lung cancer
Eren, Gülnihan; Kupik, Osman (Lippincott Williams & Wilkins, 2022)To investigate necrosis on pre-radiotherapy (RT) F-18-FDG PET/CT (PETNECROSIS) as a predictor of complete metabolic response (CMR) in patients with non-small cell lung cancer (NSCLC). We evaluated patients with inoperable ... -
Necrosis onstaging 18F FDG PET/CT is associated with worse progression-free survival in patients with stage IIIB non-small cell lung cancer
Eren, Gülnihan; Kupik, Osman (Wolters Kluwer Medknow Publications, 2022)Objective: The presence of pathological necrosis in the tumor is known to be a factor indicating worse survival. Our study defined necrosis in staging 18F-fluorodeoxyglucose positron emission tomography/computed tomography ... -
