MR imaging of the penis: What a radiologist needs to know!

Magnetic resonance imaging (MRI) plays an important role in imaging of penile pathologies due to its excellent soft tissue resolution and multiplanar imaging capabilities. This imaging review describes the MRI protocols and anatomical considerations in penile pathologies. MRI not only serves as a complementary tool to ultrasound in evaluation of trauma, infections, inflammatory diseases, and malignancies, but is also used as the definitive imaging modality for evaluation of penile prosthesis and complex cases.
