Gilbert Introduction Penile ultrasound is commonly used in the diagnostic workup of a patient with erectile dysfunction ED but also plays an important role by providing an anatomic and functional vascular assessment in a multitude of other conditions including Peyronie s disease high-flow priapism penile fracture penile urethral strictures urethral stones or diverticula or masses involving deep tissues of the penis. As a component of the evaluation for ED penile Doppler ultrasound PDU is performed to assess the quality of arterial blood flow and sufficiency of veno-occlusive mechanisms both necessary for an adequate erection. More recently this imaging modality is playing a central role in the early detection and diagnosis of otherwise silent coronary artery disease CAD in men who present with ED as their initial symptom. PDU is also an essential component of the assessment of external genitalia in trauma situations where high-flow priapism or penile fracture is suspected. Penile ultrasound provides a readily available minimally invasive S. Rais-Bahrami MD Hofstra North Shore LIJ School of Medicine The Arthur Smith Institute for Urology New Hyde Park NY USA .

Ultrasound Settings Penile ultrasound is best performed with a high-frequency linear array transducer with an ultrasound frequency of MHz which allows for high resolution images of the penis and internal vascular structures. Color and spectral Doppler are essential elements of penile ultrasonography in addition to B-mode ultrasound. 3D ultrasound is a developing technique that has the potential for better defining anatomic and vascular changes occurring with .
