Abstract
Monophasic MSCT of chest in patients with breast cancer unable to answer all diagnostic questions. However, multiphasic MSCT is associated with a significant radiation dose. In order to reduce radiation exposure for patients with breast cancer venous-arterial phase of MSCT can be used. Native, arterial and venous-arterial phases of ceMSCT of chest were compared. There was statistically significant increase of breast tumor x-ray density in venous-arterial scan (up to 2 times compared with the corresponding value in arterial phase of the study). Contrast enhancement in large vessels in venous-arterial and arterial phase scans was almost similar. Thus, the technique of venous-arterial MDCT provides a significant increase in x-ray density of breast carcinoma, keeps suitable values of contrast enhancement of the pulmonary trunk and aorta and reduces radiation dose.
