Scrotal ultrasound in adults.

Scrotal ultrasound (US) is the technique of choice for imaging the scrotal contents. US is widely used in the characterization of scrotal pathologies as a supplement to the clinical examination. Modern US equipment, precise technical performance, and knowledge of sonographic anatomy and pathology, as in any US examination, are the basis for a correct diagnosis. New techniques, including elastography and contrast-enhanced US, may have an added value to the diagnosis.
