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 2grandes 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.(AU)
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.(AU)

Llamamos club bibliográfico (CB) a un grupo de personas que se reúnen para realizar una lectura y un debate crítico de artículos científicos. En medicina, los CB son una parte muy importante del currículo formativo durante la residencia. En 2013 se funda el CB de la Sociedad Española de Radiología Médica (SERAM), con el objetivo de fomentar la adquisición de habilidades no interpretativas y la formación en editorialismo durante el periodo de residencia. Tras casi 10 años de trayectoria han formado parte del CB SERAM más de 137 revisores de 54 hospitales diferentes. En este tiempo, el número de revisores, publicaciones y visitas a nuestro sitio web han aumentado progresivamente. Actualmente, el CB SERAM funciona a través de un flujo de trabajo estructurado, organizado por grupos trimestrales y sustentado por un sistema de revisión por pares. Entre los objetivos de futuro del CB SERAM figuran internacionalizar su contenido más allá de la comunidad hispanohablante, aumentar su presencia en redes sociales (RR.SS) e incorporar contenido audiovisual.(AU)
We define a journal club as a group of people who meet to critically read and discuss scientific articles. In medicine, journal clubs are a very important part of training during residency programs. In 2013, the Spanish Society of Medical Radiology's (SERAM) journal club was established with the aim of promoting the acquisition of non-interpretative skills and training in scientific journalism during residency. After nearly 10 years, more than 137 reviewers at 54 hospitals have formed part of the SERAM's journal club. In this time period, the number of reviewers, publications, and visits to our website have increased progressively. The SERAM's journal club currently employs a structured workflow that is organized into quarterly groups and supported by a peer-review system. In the future, the SERAM's journal club aims to internationalize its content beyond the Spanish-speaking community, increase its presence in social networks, and incorporate audiovisual content.(AU)
