Neuroendocrine tumors (NETs) are rare neoplasms arising from the diffuse endocrine system and spreading throughout the different organs and tissues of the body. Tumor-induced osteomalacia (TIO) , is a rare, serious paraneoplastic syndrome primarily derived from a benign tumor of mesenchymal tissue. NETs and mesenchymal tumors are often insidious and are undetectable by conventional imaging techniques including ultrasound, computed tomography and magnetic resonance, while a permanent cure will rely on exact localization and completely removal of the tumor. Positron emission tomography (PET) provides a valuable tool for the diagnosis and differential diagnosis, staging, efficacy evaluation and recurrence monitoring of various tumors. NETs and mesenchymal tumors overexpress somatostatin receptors (SSTRs), so molecular imaging using radiolabeled somatostatin analogues may be one of the best ways to detect the occult tumors. Recently, somatostatin analogue labelled with gallium-68 (68Ga-DOTA-TATE) as a novel positron tracer has shown to be effective for the detection of NETs and mesenchymal tumors. In this prospective study, the investigators will use the most advanced imaging equipment, integrated PET/MR，and PET / CT with specific imaging agent 68Ga-DOTA-TATE and conventional imaging agent [F-18]fluorodeoxyglucose to image patients suspected or confirmed NETs and TIO, the aim is to explore the value of hybrid PET/MR and PET/CT in neuroendocrine diseases and TIO.

Study Type
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies. |

Trial ID:
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries. |
NCT04045834 |
|
Phase
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use. |
