Materials and MethodsMaterials and Methods•5 Pre-menopausal healthy women were enrolled.
•Each women was measured 3-4 times during the menstrual cycle.•Subject were followed for 1-3 months.
•Subjects were imaged for 1500 consecutive seconds.•500 second baseline (2 time points/second).•Repeat Valsalva maneuver of 40mm Hg for 30-40 seconds. •200 second rest period.
•Subjects had each breast imaged separately using 25 source x 29 detector array.
•Data analysis consisted of applying various signal processing routines to the image time series.

ConclusionsConclusions
•Vascular response of breast to the Valsalva maneuver is mainly coherent and repeatable.
•Response profile to Valsalva maneuver varies over the menstrual cycle.
•Largest variation in profile is seen with deoxy-hemoglobin whereas largest variation in rate is seen with oxy-hemoglobin.
