RESUMO:

During pregnancy and lactation breasts undergo important changes that are not fully understood. Ultrasound and magnetic resonance are the most suitable methods to assess breast alterations during pregnancy and lactation, making a solid knowledge of anatomy and breast diseases essential. Moreover, there are few articles on breast imaging, relating anatomy and physiology during the pregnancy-postpartum cycle. The present study aimed to assess physiological breast changes using ultrasound and dopper flowmetry of mammary arteries in normal pregnant and lactating women, compared to a group of non-pregnant women evaluated in the folicular and luteal phases of the menstrual cycle. This cross-sectional observational study was conducted between August 2013 and August 2016, with 203 women. The dependent variables were measures of skin, subcutaneous adipose tissue, fibroglandualr tissue, retromammary adipose tissue, duct diameter, as well as pulsatility (PI) and resistive indices (RI) of internal mammary arteries. The independent variables were the different assessment moments, represented by the five groups established. Statistical analysis involved calculating the means and standard deviations using two MANOVA models (Multivariate Analysis of Variance) to assess the group effect on the average values obtained. ANOVA models were individually fit to the mean values. The Tukey-Kramer multiple comparisons test was applied to analyze intergroup differences and characteristics, at a 5% significance level. 

Based on the data collected,  one article with partial results, assessing only groups of pregnant women, was published in the Revista Brasileira de Ginecologia e Obstetrícia (RBGO) and a review article in the journal Radiologia Brasileira. A third article, submitted and accepted for publication by the jornal Clinical and Experimental Obstetrics and Gynecology, showed changes in women during the pregnancy-lactation cycle that exhibed diferences in the measures of skin, fibroglandular tissue, subcutaneous adipose tissue and duct diameter,   when compared to non-pregnant women. Data analysis revealed no significant differences between the groups of pregnant and lactating women.
