For patient safety, patients exceeding the posted weight restrictions will not be done at London X-Ray Associates. The weight limit for all Ultrasound exams is 350 lbs.


Ultrasound uses sound, not x-rays, to produce images. A probe placed on the surface of the body sends a thin, high-frequency sound beam (above the range that humans can hear) into the body. The sound bounces off of structures within the scrotum and back to the probe. A computer is able to construct images based on the time required for these echoes to return. Doppler ultrasound allows us to determine the direction and speed of blood flow. Testicular ultrasound with doppler examination takes approximately 30 minutes.

Common reasons for a testicular ultrasound

Some of the more common reasons why your doctor would order a testicular ultrasound would include:

Who should not have a testicular ultrasound?

Ultrasound is an extremely safe procedure and there are very few conditions that would prevent it from being performed. Since the probe must be placed in contact with the skin, the scrotum must be exposed.

How do I prepare for the test?

There is no preparation required for a testicular ultrasound.

Who performs the examination?

An ultrasound technologist (a person trained to take ultrasound images) performs the examination. At London X-ray Associates, all of our technologists have met and maintain registration standards with the international governing body, the American Registry of Diagnostic Medical Sonographers.

What happens during the examination?

After registering with the receptionist you will be asked to change into a gown. You will have to remove your pants and underwear. You will be taken to the examination room which contains an ultrasound machine and an examination table. You will be asked to lie on the table on your back. The gown will be raised to expose the scrotum. Towels will be placed between your legs and around the scrotum to help immobilize the testicles. The penis is covered. The technologist will apply a gel to your skin to improve contact with the probe. The technologist will move the probe to various positions on both right and left sides taking ultrasound pictures. Doppler will also be used to examine blood flow. When Doppler is being used, you will hear a noise from the ultrasound machine. You may be asked to hold your breath to look for changes in blood flow.

At the end of the examination you will be given materials to clean yourself.

What can I expect after the examination?

Testicular ultrasound has no after-effects and you should be able to return to activities of daily living.

What are the risks of the procedure?

Ultrasound is an extremely safe procedure that does not expose the body to x-rays. Ultrasound transmits very small quantities of sound energy into the body but this produces no known harmful effects when standard techniques are used.

Who interprets the results and how do I get them?

The results are interpreted by one of our radiologists (a doctor who is trained to interpret x-rays and other medical images) and the results are sent to the doctor who ordered the ultrasound by courier or fax.

Arrangements to discuss the results of the ultrasound can be made with the doctor who ordered the test.

Are childcare (baby sitting) services available while I have my exam?

No childcare services are available. Please prearrange the following:
Adult supervision in the waiting room must be provided at all times for children while you, the caregiver, are having your exam completed. London X-Ray Associates staff will not be able to provide any childcare needs. We ask that all children be supervised by an adult, other than the patient, while at London X-Ray Associates.
Thank you.
