CUBIDES, Carlos; RESTREPO, Gustavo; ARISTIZABAL, Dagnóvar  e  MUNERA, Ana. Contrast echocardiography: history, micro bubble characteristics and instrumental techniques. Rev. Colomb. Cardiol. [online]. 2006, vol.12, n.6, pp.443-451. ISSN 0120-5633.

This article describes the history of contrast echocardiography, the physical characteristics of the contrast agents’ micro bubbles, the main instrumental tools (mechanical index, focus and focusing, frame rate), and the echocardiography techniques (second harmonic imaging, fusion harmonic, power pulse inversion imaging, triggered imaging, intermittent harmonic power Doppler, color power angio and acoustic densitometry), actually available for clinical use.

Palavras-chave : contrast echocardiography; echo-potentiators; micro bubbles; second harmonic; mechanical index; bubble characteristics; instrumental techniques.
