Penile ultrasound can be used to assist the diagnosis of penile fracture; it can be easily performed, is non-invasive and useful in determining localized sub-Buck's fascia hematoma due to injury or to causes other than tunical tear.[sup.6] Also magnetic resonance (MR) imaging is potentially useful to assess the penile rupture; the key finding is disruption of the low-signal intensity tunica albuginea, which is well-seen on both T1 and T2 weighted images, although T1 weighted sequences may detect more subtle fractures.[sup.7]
