- W4220939931 abstract "La secuencia fluid attenuated inversion recovery (FLAIR) forma parte hoy en día de la gran mayoría de protocolos diagnósticos de RM cerebral. Esta secuencia de inversión-recuperación permite una supresión de la señal del líquido cefalorraquídeo, lo que facilita la detección de enfermedad que afecta al espacio subaracnoideo. Las causas de hiperintensidad del líquido cefalorraquídeo en esta secuencia pueden subdividirse en 2 grandes grupos, las patológicas y las debidas a artefactos. Son bien conocidas la etiología tumoral, la inflamatoria, la vascular o las debidas a hipercelularidad del líquido cefalorraquídeo o a ocupación por contenido hemático. Sin embargo, existen numerosas condiciones no patológicas, principalmente debidas a artefactos, que se relacionan con este hallazgo constituyendo una potencial fuente de errores diagnósticos. The fluid-attenuated inversion recovery (FLAIR) sequence forms part of the vast majority of current diagnostic protocols for brain MRI. This sequence enables the suppression of the signal from cerebrospinal fluid, facilitating the detection of disease involving the subarachnoid space. The causes of hyperintensity in the arachnoid space in this sequence can be divided into two main categories: hyperintensity due to disease and hyperintensity due to artifacts. Hyperintensity due to tumors, inflammation, vascular disease, or hypercellularity of the cerebrospinal fluid or hematic contents is well known. However, numerous other non-pathological conditions, mainly due to artifacts, that are also associated with this finding are a potential source of diagnostic errors." @default.
