MRI of the penis

Area of Science:

• Radiology
• Medical Imaging
• Urology

Background:

• Magnetic Resonance Imaging (MRI) is a sophisticated imaging modality.
• Penile MRI, while costly, provides detailed visualization of penile structures.
• Specific MRI sequences combined with pharmacologic erection can enhance image quality.

Purpose of the Study:

• To review the radiological anatomy of the penis using MRI.
• To discuss and delineate the clinical indications for penile MRI.
• To highlight MRI's role in diagnosing and managing various penile pathologies.

Main Methods:

• Review of penile radiological anatomy.
• Discussion of clinical applications and indications for MRI.
• Utilizing high-resolution T2-weighted sequences with intracavernosal alprostadil-induced tumescence.

Main Results:

• MRI effectively visualizes the glans, corpora, and tunica albuginea.
• Penile MRI is indicated for staging penile cancer when clinical staging is uncertain.
• It is valuable for assessing corporal viability in priapism, diagnosing penile fractures, aiding surgical planning in Peyronie's disease, and evaluating malfunctioning penile prostheses.

Conclusions:

• Penile MRI is a valuable diagnostic tool for specific urological conditions.
• It offers superior visualization of penile anatomy compared to other methods in select cases.
• Indications include cancer staging, priapism assessment, fracture diagnosis, and prosthesis evaluation.
