Abstract

Spectral computed tomography has represented a major breakthrough in radiology thanks to its multiple applications and potential to provide more information than conventional CT techniques. It is very useful for diagnosing and describing findings as well as the management of patients, thus avoiding further imaging or invasive procedures.

The aim of this article is to explain basic concepts of spectral CT and highlight key practical features in a range of abdominal and pelvic pathologies, along with a brief description of different post-processing maps and their clinical applications including incidental, oncological and urgent findings.

Resumen

La tomografía computarizada (TC) de energía espectral ha supuesto un avance importante en radiología, ya que sus múltiples aplicaciones aportan información adicional respecto a la TC convencional. Es muy útil para el diagnóstico y caracterización de hallazgos, así como para el manejo de los pacientes, evitando, en muchas ocasiones, la necesidad de realizar pruebas adicionales y procedimientos invasivos.

El objetivo de este artículo es explicar conceptos básicos de la TC espectral y mostrar puntos clave y prácticos en patología abdomino-pélvica variada. Se muestran los distintos mapas de postproceso y sus aplicaciones clínicas incluyendo hallazgos incidentales, oncológicos y de urgencias.
