Este estudio se centra en comprender cómo se comporta un agente de imagen especial llamado 18F-Fluoromannitol (18F-FMtl) en el cuerpo y en verificar su seguridad. Este agente se utiliza en un tipo de escaneo llamado PET, que ayuda a los médicos a ver dentro del cuerpo. El estudio involucra a voluntarios adultos sanos y es importante porque el 18F-FMtl no está disponible para uso general y no ha sido probado en humanos antes. Al evaluar cómo este agente se mueve a través del cuerpo, los investigadores pretenden recopilar información importante sobre la seguridad, lo que podría llevar a mejores herramientas de diagnóstico en el futuro. Los participantes en este estudio recibirán 18F-FMtl a través de una inyección intravenosa, lo que significa que se administra directamente en el torrente sanguíneo. Tras esto, se realizarán escaneos PET para rastrear el movimiento y la acumulación del agente en el cuerpo. Además, los investigadores recopilarán muestras de sangre y orina, monitorearán los signos vitales y revisarán cualquier síntoma para garantizar la seguridad. El estudio está cuidadosamente diseñado para evaluar estos factores, proporcionando una comprensión integral del comportamiento y perfil de seguridad del agente.
Inclusion Criteria: Healthy volunteers, 18-75 years of age. * Female participants of childbearing age must not be lactating due to theoretical potential harm to the infant from exposure to radiation. * Informed consent signed by participant according to the guidelines of the institutional review board. Exclusion Criteria: * Participant currently has a fever or other symptoms concerning for an active infection or is currently undergoing treatment for an active infection. * Participant has been diagnosed and/or treated for a known or suspected bacterial infection within the past 60 days. * Participant has known disease of the lung, liver, kidneys, gastrointestinal tract, bones/joints, or known immune suppression or autoimmune disease that is likely to have active inflammation (examples to exclude: Crohn's disease, COPD; example to i include: well controlled asthma) * Participant has prosthetic or indwelling device(s) currently or has had one in the past 60 days. * Participant is pregnant or breastfeeding. * Estimated glomerular filtration rate \< 45 ml/minute/1.73m2 * Use of drugs known to have interaction or be affected by mannitol within 60 days of enrollment. * Participant has any condition that would, in the opinion of the investigator, place the subject at an unacceptable risk of injury or render the subject unable to meet the requirements of the protocol, including being unable to tolerate the PET scan procedures. * Inability or unwillingness of research participant or legal guardian/representative to give written informed consent. * Participant is currently participating in another study subject to an IND.
