Ultrasound or sonography involves sending sound waves into the body. These sound waves are reflected off the internal organs and are recorded by special instruments that create images of anatomic parts. No ionizing radiation (x-ray) is involved in ultrasound imaging. Ultrasound images are captured in real-time so they can show movement of internal tissues and organs, such as the flow of blood in arteries and veins.
Ultrasound imaging of the scrotum is the primary imaging method used to evaluate disorders of the testicles and surrounding areas. It is used when a patient is experiencing pain or swelling in the scrotum, a mass has been felt by the patient or doctor, or there has been trauma to the scrotal area.
Prostate ultrasound is used to detect possible disorders within a man's prostate gland. Ultrasound images can indicate when the prostate is enlarged or when there is an abnormal growth that might be cancer.
