|
What are some limitations of penile imaging?
|
High level of anxiety
Duplex needed for velocities Sensitivity to injectable medication |
|
|
What do you do first for penile study?
|
Calculate ABI
|
|
|
Why do you calculate ABI for penile study?
|
Because poor arterial inflow to lower extremities due to proximal obstruction may affect penile arterial flow
|
|
|
Where do you place the probe during penile imaging?
|
Lateral or ventral
|
|
|
What other vessels do you document flow in for penile imaging?
|
CFA, PTA and DPA
|
|
|
What is a normal penile brachial index?
|
>.75
|
|
|
What is considered marginally abnormal penile brachial index?
|
.65-.74
|
|
|
What is considered an abnormal penile brachial index?
|
<.65
|
|
|
Prior to injection what vessels are evaluated with imaging?
|
Cavernous arteries are measured in AP diamter. PSV and EDV are obtained
|
|
|
After injection what vessels are evaluated with imaging?
|
Same as before injection
|
|
|
What should happen to cavernous arteries post injection?
|
Diameter should increase
|
|
|
What should happen to PSV post injection?
|
Should increase. PSV should be 30cm/sec or higher
|
|
|
Should dorsal vein velocites increase post injection?
|
No
|
|
|
If dorsal vein velocities increase what does this suggest?
|
Venous leak
|
|
|
What is a normal velocity of dorsal vein?
|
<3 cm/sec
|
|
|
What is an abnormal velocity of dorsal vein?
|
>20cm/sec
