The purpose of this research study is to test new ways to improve the usefulness of the world's first total-body positron emission tomography (PET)/computed tomography (CT) scanner (EXPLORER) by collecting data from PET scans using one of three different imaging agents: 18F-PSMA; 18F-FES; or, 68Ga DOTATATE. These imaging agents are approved by the FDA to be used for patients diagnosed with prostate cancer (18F-PSMA), neuroendocrine tumor (68Ga DOTATATE), or breast cancer (18F-FES).
The purpose of this study is to investigate the pathologic features, complications, and prognostic factors of functioning adrenal adenoma and suggest follow-up algorithms for adrenal incidentaloma.
This study is being done to determine if CEST magnetic resonance imaging (MRI) and FDG PET are feasible techniques to detect metabolic differences between tumor and brain in patients with a brain tumor.
The aim of this study is to look at the long-term safety and clinical parameters of somapacitan in paediatric participants with growth hormone deficiency under routine clinical practice conditions. The study population will include 400 paediatric growth hormone deficient participants from the Global Registry for Novel Therapies in Rare Bone and Endocrine Conditions (GloBE-Reg) treated with once-weekly somapacitan and fulfilling the eligibility criteria of the study. The total duration of the study is planned to 10 years consisting of a 5-year recruitment period in the GLoBE-Reg followed by a 5-year follow-up period.
This reader study aims at assessing whether the radiologist aided with AI software has at least a non-inferior performance than without AI assistance in detecting brain metastases. 200 retrospective MRI images will be included in the study with 100 positive and 100 negative exams. Assessment will be completed by 12 readers with varying level of experience. This is a Retrospective Multiple-Reader Multiple-Case (MRMC) randomised study.
Postoperative cerebrospinal fluid (CSF) leakage is a well-known complication that might occur after transnasal transsphenoidal adenomectomy at an incidence of 0.5-15% according to different literature reports. Persistent CSF leakage may lead to intracranial hypotension or meningitis, therefore aggressive management is mandatory. The treatment is immediate repair during transsphenoidal surgery once intraoperative CSF leakage is identified, with the adjunct of postoperative bed rest and/or lumbar drainage. However, due to the advances in endoscopic endonasal skull base surgery, some surgical teams have advocated that postoperative bed rest may not be necessary if appropriate repair...
A small tube will go through the respiratory tract and a non contact cauterization will be done to the inside tumor
A retrospective crosssectional observational study of the effects of oncological treatment and frequent general anesthesia on neuropsychological development, psychosocial functioning (in terms of anxiety, depression, peer relations, perceived cognitive functioning and potential trauma) and health related quality of life in children and young adults who were treated or screened for retinoblastoma.
To determine the minimum scan duration for fluorine-18 positron-emitting radioactive isotope-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET)/computed tomography (CT) scans performed on a total-body PET/CT scanner that results in non-inferior image quality to 18F-FDG PET/CT scans performed on a conventional PET/CT scanner. The subject population will be patients being staged for lung cancer, lymphoma, or melanoma.
This study is designed to evaluate the safety and efficacy of cord blood-derived CAR-NK019 in the treatment of refractory/relapsed central nervous system lymphoma.
