The use of ultrasound to identify milk ejection in women - tips and pitfalls.

Bottom Line: At milk ejection, the echogenic duct walls expand as milk flows forward towards the nipple.Milk flow appears as echogenic foci rapidly moving within the milk duct.This paper provides a detailed description of the ultrasound technique used for the detection and reviews nuances associated with the procedure.

ABSTRACT
Diagnostic ultrasound imaging of the breast has been limited principally to the abnormal, non-lactating breast. Due to the rapid improvement of imaging technology, high-resolution ultrasound images can now be obtained of the lactating breast. Ultrasound scanning techniques, however, require modifications to accommodate the breast changes that occur in lactation. Furthermore, the function of the breast with regard to milk ejection can be assessed with ultrasound by identification of milk duct dilation and milk flow. At milk ejection, the echogenic duct walls expand as milk flows forward towards the nipple. Milk flow appears as echogenic foci rapidly moving within the milk duct. This paper provides a detailed description of the ultrasound technique used for the detection and reviews nuances associated with the procedure.

Plot of duct diameter measured using ultrasound imaging during a 15-minute expression session using an electric breast pump. Six duct diameter dilations (milk ejections) lasting approximately 100 seconds each were detected during this pumping session.

Figure 10: Plot of duct diameter measured using ultrasound imaging during a 15-minute expression session using an electric breast pump. Six duct diameter dilations (milk ejections) lasting approximately 100 seconds each were detected during this pumping session.

Mentions: Retrospective analysis of the videotape is carried out in order to measure milk duct diameter every three to twenty seconds, that is, at times when the breast has stabilized from movement of the mother, baby or the positioning of the transducer. This enables one to plot milk duct diameter over the length of the feed/pumping session. These plots enable better evaluation of both the number and the duration of the milk ejections. Figures 9 and 10 show the variation of milk ejection patterns between women. The duration of milk ejection has been estimated from the beginning of an increase in duct diameter to the beginning of the next increase in duct diameter [4].
