Comparison of monophasic vs biphasic administration of contrast material in non-invasive coronary angiography using a 16-row multislice Computed Tomography.

Abstract

No significant differences of the attenuation values were observed at the origin of the coronary arteries (p>0.05). The attenuation profile of the monophasic protocol showed higher and longer attenuation values than the biphasic protocol. CONCLUSIONS. The biphasic administration of contrast material does not supply significant advantages on the enhancement of the great vessels and the coronary arteries in 16-row MSCT coronary angiography.
