Comparison of computed tomography, magnetic resonance imaging and positron emission tomography in detecting cartilage invasıon in larynx cancers
(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 ... -
Contribution of F-18 fluorodeoxyglucose PET/CT and contrast-enhanced thoracic CT texture analyses to the differentiation of benign and malignant mediastinal lymph nodes
(Sage Publications, 2022)Background Texture analysis and machine learning methods are useful in distinguishing between benign and malignant tissues. Purpose To discriminate benign from malignant or metastatic mediastinal lymph nodes using F-18 ... -
Is there any correlation between levels of serum ostepontin, CEA, and FDG uptake in lung cancer patients with bone metastasis?
(Elsevier Espana Slu, 2016)Objective: in this study, an evaluation was made of the relationship between the serum levels of carcinoembryonic antigen (CEA), osteopontin (OPN), and the semi-quantitative parameters of 18-fluoro2-deoxyglucose positron ... -
Necrosis on pre-radiotherapy F-18-FDG PET/CT is a predictor for complete metabolic response in patients with non-small cell lung cancer
(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
(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 ... -
Relationships between dce-mri, dwi, and18f-fdg pet/ct parameters with tumor grade and stage in patients with head and neck squamous cell carcinoma
(Galenos Yayıncılık, 2021)Objectives: Properties of head and neck squamous cell carcinoma (HNSCC) such as cellularity, vascularity, and glucose metabolism interact with each other. This study aimed to investigate the associations between ...
