68GA-FAPI-04 PET/CT Versus 18F-FDG PET/CT in Imaging of Malignant Mixed Germ Cell Testicular Tumor
Kaplan, Ihsan; Can, Canan; Guzel, Yunus; Alabalik, Ulas; Komek, Halil (Lippincott Williams & Wilkins, 2023)F-18-FDG PET/CT imaging was performed for restaging in in a 16-year-old boy who was operated on for right testicular tumor and was diagnosed with malignant mixed germ cell tumor. Mild FDG uptake was observed in 2 nodules ... -
68Ga-FAPI-04 PET/CT Versus 18F-FDG PET/CT in Malignant Peritoneal Mesothelioma
Gundogan, Cihan; Guzel, Yunus; Komek, Halil; Etem, Hulya; Kaplan, Ihsan (Lippincott Williams & Wilkins, 2022)[Abstract Not Available] -
Comparison of 18F-FDG PET/CT and 68Ga-FAPI-04 PET/CT in patients with non-small cell lung cancer
Can, Canan; Kepenek, Ferat; Komek, Halil; Gundogan, Cihan; Kaplan, Ihsan; Tasdemir, Bekir; Guzel, Yunus (Lippincott Williams & Wilkins, 2022)Aim In this study, we aimed to compare the diagnostic accuracy of F-18-fluorodeoxyglucose (F-18-FDG) and Gallium-68 labeled fibroblast activator protein inhibitor (Ga-68-FAPI)-04 PET/CT in the tumor-node-metastasis (TNM) ... -
Evaluation of dual time-point fluorodeoxyglucose PET/computed tomography imaging in gastric cancer
Tasdemir, Bekir; Guzel, Yunus; Komek, Halil; Can, Canan (Lippincott Williams & Wilkins, 2020)Background We aimed to evaluate the efficiency of dual time-point fluorodeoxyglucose (FDG) PET/computed tomography (CT) imaging in detecting primary and metastatic lesions in gastric cancer. Methods Between May 2019 and ... -
False-Positive 68Ga-Fibroblast Activation Protein-Specific Inhibitor Uptake of Benign Lymphoid Tissue in a Patient With Breast Cancer
Gundogan, Cihan; Guzel, Yunus; Can, Canan; Alabalik, Ulas; Komek, Halil (Lippincott Williams & Wilkins, 2021)Ga-68-fibroblast activation protein-specific inhibitor (FAPI)-04 PET/CT was performed in a patient with left lower outer quadrant breast cancer who had F-18-FDG PET/CT imaging. Ga-68-FAPI-04 PET/CT showed higher accumulation ... -

Yildirim, Ozgen Ahmet; Poyraz, Kerem; Erdur, Erkan; Can, Canan; Gundogan, Cihan; Guzel, Yunus; Etem, Hulya (Taylor & Francis Inc, 2021)To evaluate ICIs related dry eye and dry mouth in nivolumab therapy, 24 patients receiving nivolumab (group 1), 30 patients in remission without treatment for 6 months (group 2), 30 healthy participants (group 3) were ... -
Perirenal Infiltration of Signet Ring Cell Colon Carcinoma Shown by 68Ga-FAPI PET/CT
Guzel, Yunus; Kaplan, Ihsan; Kepenek, Ferat; Sogutcu, Nilgun; Komek, Halil (Lippincott Williams & Wilkins, 2022)A soft tissue lesion surrounding the left kidney was detected in F-18-FDG PET/CT performed with suspicion of recurrence in a patient who was operated for descending colon cancer and showed mild FDG uptake. Intense fibroblast ... -
