ABSTRACT

Junto con un aumento sostenido en la incidencia de cáncer de próstata en los países desarrollados ha habido un cambio en el enfrentamiento diagnóstico en estos pacientes. El diagnóstico tradicional basado en la medición del antígeno prostático específico y la biopsia randomizada ha mostrado tener muchas falencias ya que sobre-diagnostica cánceres no significativos y sub-diagnostica cánceres clínicamente significativos. La resonancia magnética de próstata multiparamétrica ha demostrado ser útil ya que disminuye este tipo de falencias. En este artículo se revisará la historia de la resonancia magnética de próstata y del PI-RADS, con el objeto de revisar el rendimiento de estos métodos y sus indicaciones actuales.


Along with a sustained increase in the incidence of prostate cancer in developed countries, there has been a change in the diagnostic approach in these patients. The traditional diagnosis based on the measurement of the specific prostate antigen and randomized biopsy has shown to have many shortcomings as it leads to overdiagnosis of non-significant cancers and underdiagnosis of clinically significant cancers. The multiparametric prostate magnetic resonance imaging has proven to be useful since it diminishes these shortcomings. In this article we will review part of the history of prostate magnetic resonance imaging and PI-RADS, in order to review the performance of these methods and their current indications.
