La FDA aprueba floretirosina F 18 o18F-FET para la estadificación y seguimiento PET de gliomas cerebrales
La agencia regulatoria estadounidense otorgó la aprobación a este nuevo radiofármaco dirigido a transportadores de aminoácidos para tomografía por emisión de positrones (PET) en neoplasias del sistema nervioso central
A diferencia de la resonancia con contraste, que suele presentar falsos positivos por disrupción de la barrera hematoencefálica o radionecrosis (pseudoprogresión), el nuevo trazador molecular permite diferenciar con alta especificidad el tejido tumoral activo de los cambios inflamatorios post-radioterapia tanto en pacientes adultos como pediátricos.
