Abstract

The growing demand for computed tomography studies clashes with the restrictions on the use of ionizing radiation that are being reflected more and more clearly in good practice guidelines and legislation. One paradigmatic example is the diagnosis of acute diverticulitis, for which more and more computed tomography studies are being demanded with the justification that they are clinically necessary and more reliable than ultrasound studies. The present paper reviews the scientific evidence about the diagnostic validity of ultrasonography and computed tomography in the diagnosis of acute diverticulitis of the colon.

Keywords:
Diagnosis
Ultrasonography
Computed tomography
Colonic diverticulitis
Resumen

La demanda creciente de estudios de tomografía computarizada confronta con las restricciones cada vez más claras que imponen la legislación y la buena praxis al empleo de radiaciones ionizantes. Un paradigma de ello es el diagnóstico de la diverticulitis aguda, para el que cada vez más se exigen estudios de tomografía computarizada justificándolos en las necesidades clínicas y una mayor fiabilidad respecto a la ecografía. El presente trabajo revisa la evidencia científica sobre la validez diagnóstica de la ecografía y la tomografía computarizada en el diagnóstico de la diverticulitis aguda de colon.

Palabras clave:
