Ankle brachial index = 1.2

Ankle brachial index is useful to evaluate the status of the peripheral vasculature, especially in diabetic individuals. Ankle brachial index is the ratio of the ankle systolic blood pressure to the brachial systolic pressure.

Colour Doppler image of popliteal artery and vein

Longitudinal ultrasound image of the popliteal artery and vein with colour flow mapping. Blue colour indicates flow away from the transducer and red colour indicates flow towards the transducer. The light green quadrilateral is the colour Doppler sample volume. The vein appears larger than the artery in the two dimensional ultrasound image.

Femoral artery Doppler pattern

(Click on  image for an enlarged view)

Doppler ultrasound tracing from the left femoral artery is seen the lower panel. The tall upward component is the predominant systolic flow. The graduation at the right end is the velocity in cm/sec. The upper panel shows the longitudinal image of the femoral artery seen as a dark longitudinal shadow in the middle of the image. The imaging line with cursor within the lumen of the femoral artery is also seen in the upper panel.
