Abstract

Spectral CT technology is based on the acquisition of CT images with X-ray at 2 different energy levels which makes possible to distinguish between materials with different atomic numbers using their energy-dependent attenuation, even if those materials have similar density at conventional CT.

This kind of technology has gained wide application due to the innumerable uses of their post-processing techniques, including virtual non-contrast images, iodine maps, virtual mono-chromatic images or mixed images without increasing radiation dose.

There are several applications of spectral CT in Emergency Radiology that help in the detection, diagnosis and management of various pathologies such as differentiate haemorrhage from the underlaying causative lesion, diagnosis of pulmonary embolisms, demarcation of abscess, characterization of renal stones or reduction of artifacts.

The purpose of this review is to provide the emergency radiologist a brief description of the main indications for spectral CT.

Resumen

La TC espectral se basa en la adquisición de imágenes de TC con rayos X a 2 niveles de energía distintos, lo que hace posible la diferenciación de los distintos materiales que presentan diferente número atómico. Esto es debido a que estos materiales presentan diferente atenuación con los distintos niveles de energía empleados, incluso aunque su atenuación sea similar a la de la TC convencional.

Este tipo de tecnología se ha generalizado debido a las importantes ventajas que ofrecen sus técnicas de posprocesado, incluyendo las imágenes sin contraste virtual, mapas de yodo, imágenes virtuales monoenergéticas o reconstrucciones mixtas, todo ello sin aumentar la dosis de radiación.

La TC espectral tiene múltiples aplicaciones en la radiología de urgencias que permiten una mejora en la detección, el diagnóstico y el manejo de distintas enfermedades.

El objetivo de esta revisión es describir brevemente las principales indicaciones de la TC espectral en urgencias.
