MR imaging of nonmalignant penile lesions

Area of Science:

• Radiology
• Urology
• Medical Imaging

Background:

• Magnetic resonance (MR) imaging is an evolving diagnostic tool.
• Its application in benign penile diseases requires further elucidation.

Purpose of the Study:

• To evaluate the utility of MR imaging in the assessment of various benign penile conditions.
• To determine the specific diagnostic capabilities of MR imaging for conditions including penile fracture, Peyronie disease, priapism, penile prostheses, erectile dysfunction, and urethral strictures.

Main Methods:

• Utilized T1- and T2-weighted MR imaging sequences.
• Administered intravenous contrast material in cases of priapism.
• Assessed the tunica albuginea, corpora cavernosa viability, and fibrosis.

Main Results:

• MR imaging clearly delineates the tunica albuginea, aiding in diagnosing penile fracture and Peyronie disease.
• Contrast-enhanced MR imaging assists in assessing corpora cavernosa viability and fibrosis in priapism.
• MR imaging provides excellent anatomical detail for penile prosthesis assessment.
• MR imaging shows limited value in evaluating erectile dysfunction and has not proven superior for urethral strictures.

Conclusions:

• MR imaging is a valuable tool for diagnosing penile fracture, Peyronie disease, and assessing penile prostheses.
• It offers benefits in evaluating priapism but has limited utility for erectile dysfunction and urethral strictures.
