There are several modes of ultrasonography among which is the duplex (Latin, two) ultrasonography which combines conventional ultrasonography with Doppler (named after physicist C Doppler) ultrasonography.  Ultrasonography creates pictures while Doppler ultrasonography measures and visualises blood flow.

Pharmaco-penile duplex ultrasonography (PPDU) is duplex ultrasonography with intracavernosal injection of vasoactive substance(s) where, the penile arteries are examined by a combination of conventional ultrasound and a Doppler ultrasonography to measure velocity.

What do the findings in figure 1 suggest?
What do the findings in figure 2 suggest?
What do the findings in figure 3 suggest? 

Is direct measurement of velocity in deep dorsal vein of the penis useful in PPDU?
