Abstract

CT coronary angiography is the most reliable non-invasive imaging technique for ruling out coronary artery disease. However, its specificity is not high. Thus, when coronary stenosis of uncertain functional significance is detected, the recommendation is to perform complementary imaging tests to assess myocardial ischemia. CT myocardial perfusion imaging and CT fractional flow reserve provide added diagnostic accuracy and prognostic value to CT coronary angiography, by increasing its predictive value and facilitating therapeutic decision-making.

Keywords:
Coronary computed tomography angiography
Computed tomography myocardial perfusion imaging
Computed tomography fractional flow reserve
Resumen

La coronariografía por TC es la técnica de imagen no invasiva más fiable para descartar enfermedad coronaria. Su especificidad, sin embargo, no es alta. Por ello, ante la presencia de estenosis coronarias con significado funcional incierto, se recomienda completar el estudio con pruebas de imagen dirigidas a la detección de isquemia miocárdica. La perfusión miocárdica por TC y la determinación de la reserva fraccional de flujo por TC proporcionan un valor diagnóstico y pronóstico adicional a la coronariografía por TC, aumentando el valor predictivo de la prueba y facilitando la toma de decisiones terapéuticas.

Palabras clave:
Coronariografía por tomografía computarizada
Perfusión miocárdica por tomografía computarizada
Reserva de flujo fraccional por tomografía computarizada
