At present, CTA is superior and preferred over MRA for studying the arteries of the heart. The CT scanner to be used to properly study the coronary arteries must be no less than 64 detector rows (available from all major CT companies) or two-tube x-ray equipment (currently only available from some Siemens company models).

Las arterias son estudiadas con mayor frecuencia que las venas. CTA representa la versión no invasiva de un cateterismo obtenida en un equipo de tomografía computadorizada (CT).
