Increase in milk duct visualised by ultrasound at milk ejection. This movie depicts milk duct dilation in the right breast at milk ejection when monitored with ultrasound. The left breast was expressed with an electric breast pump. As milk duct diameter increases milk flow can be visualised as echogenic (white flecks) moving toward the nipple (right side of the image). (The file is MPG format and can be viewed with either Apple QuickTime Player or Microsoft Windows Media Player).
