This examination can be performed in the same session as that by 2D and 3D ultrasound. This type of ultrasound takes advantage of the Doppler effect and allows the evaluation of the speed of blood flow to be determined within the blood vessels that feed the ovaries and the uterus. Doppler ultrasound provides two types of information. First, it allows the visualization and quantity of vessels present in a given region. Second, it enables the graphic evaluation of variations in blood flow velocity in the systolic and diastolic phase of the cardiac cycle. A low flow rate during the diastolic phase signals a vasoconstriction that can be alleviated using vasodilator drugs during subsequent therapy.
