Detection of Atherosclerotic Inflammation by 68Ga-DOTATATE PET Compared to [18F]FDG PET Imaging
BACKGROUND Inflammation drives atherosclerotic plaque rupture. Although inflammation can be measured using fluorine-18-labeled fluorodeoxyglucose positron emission tomography ([18F]FDG PET), [18F]FDG lacks cell specificity, and coronary imaging is unreliable because of myocardial spillover. OBJECTIVES This study tested the efficacy of gallium-68-labeled DOTATATE (68Ga-DOTATATE), a somatostati...
متن کاملFDG Uptake in PET by Bladder Hernia Simulating Inguinal Metastasis
A 70-year-old man with past history of hemicolectomy due to colon cancer underwent a follow-up abdominal/pelvic CT scan. CT revealed a right adrenal metastasis and then he underwent FDG-PET/CT study to search for other possible tumor recurrence. In PET images, other than right adrenal gland, there was an unexpected intense FDG uptake at right inguinal region and at first, it was considered to b...
متن کامل68Ga-DOTATATE PET/CT imaging of indeterminate pulmonary nodules and lung cancer
PURPOSE 18F-FDG PET/CT is widely used to evaluate indeterminate pulmonary nodules (IPNs). False positive results occur, especially from active granulomatous nodules. A PET-based imaging agent with superior specificity to 18F-FDG for IPNs, is badly needed, especially in areas of endemic granulomatous nodules. Somatostatin receptors (SSTR) are expressed in many malignant cells including small cel...
متن کاملDual false positive of ⁶⁸Ga-DOTA-TATE PET/CT scan in a patient with a history of pancreatic neuroendocrine tumor: a case report.
68Ga-labeled octreotide analogs, including DOTATOC, DOTATATE and DOTANOC, are very useful PET radiopharmaceuticals in the management of neuroendocrine tumors (NETs). However, a considerable number of malignancies beyond NETs, including lymphomas, express somatostatin receptors and are eligible to accumulate radiolabeled octreotide analogs, leading to misleading findings on somatostatin receptor...
متن کاملMeningiomas: A Comparative Study of 68Ga-DOTATOC, 68Ga-DOTANOC and 68Ga-DOTATATE for Molecular Imaging in Mice
PURPOSE The goal of this study was to compare the tumor uptake kinetics and diagnostic value of three (68)Ga-DOTA-labeled somatostatin analogues ((68)Ga-DOTATOC, (68)Ga-DOTANOC, and (68)Ga-DOTATATE) using PET/CT in a murine model with subcutaneous meningioma xenografts. METHODS The experiment was performed with 16 male NUDE NU/NU mice bearing xenografts of a human meningioma cell line (CH-157...
