Editing Peyronie's Disease (section)

=== Imaging ===

* '''Options'''
** '''Ultrasound'''
*** '''Benefits (4):'''
***# '''Identification and measurement of calcification during initial surveillance in the flaccid state'''
***#* Calcification may occur early after the onset of the scarring process, not necessarily only in chronic/mature disease.
***#* '''Men with extensive calcification are less likely to benefit from non-surgical treatment'''
***# Identification of corporeal fibrosis
***# Assessment of penile vascular flow parameters after intracavernosal injection of vasoactive agent
***# Observation of the erectile response to the vasoactive injection compared to the patient’s sexually induced erection; best opportunity to objectively assess deformity (curvature, girth irregularities, hinge effect)
*** '''CUA: colour duplex ultrasonography may be offered, but may not be readily available'''; combination of ultrasound with intracavernosal injection may also identify arterial insufficiency or veno-occlusive dysfunction, influencing choice of Peyronie disease management
*** Insert figure
** '''MRI''' 
***'''Excellent imaging modality for penile pathology,''' including PD
***'''Routine use in clinical practice is not supported'''
** CT and plain radiography do not have a role
