Ultrasound imaging, also called ultrasound scanning or sonography, involves the use of a small transducer (probe) and ultrasound gel to expose the body to high -frequency sound waves. Ultrasound is safe and painless, and produces pictures of the inside of the body using sound waves. Ultrasound examinations do not use Ionizing radiation (as used in x-rays). Because ultrasound images are captured in real-time, they can show the structure and movement of the body's internal organs, As well as blood flowing through blood vessels.
Conventional ultrasound displays the images in thin, flat sections of the body. Advancements in ultrasound technology include three-dimensional (3-D) ultrasound that formats the sound wave data into 3-D images. Four-dimensional (4-D) ultrasound is 3-D ultrasound in motion.
Doppler ultrasound is a special ultrasound technique that evaluates blood flow through a blood vessel, including the body's major arteries and veins in the abdomen, arms, legs and neck.
Why should I do it ?
- Ultrasound imaging of the scrotum is the primary imaging method used to evaluate disorders of the testicles, epididymis (tubes immediately next to the testicles that collect sperm made by the testicle) and scrotum.
- This study is typically used to:
- Determine whether a mass in the scrotum felt by the patient or doctor is cystic or solid and its location.
- Diagnose results of trauma to the scrotal area.
- Diagnose causes of testicular pain or swelling such as inflammation or torsion.
- Evaluate the cause of infertility such as varicocele.
- Look for the location of undescended testis.
- A sudden onset of pain in the scrotum should be taken very seriously. A common cause of scrotal pain is epididymitis, an inflammation of the epididymis. It is treatable with antibiotics. If left untreated, this condition can lead to an abscess or loss of blood flow to the testicles.
Any preparations needed?
- Preparations depend on the type of ultrasound you are having.
- You should wear comfortable, loose-fitting clothing.
- You may need to remove all clothing and jewelry in the area to be examined.
