Ultrasound

Ultrasound is a type of medical imaging that uses high frequency sound waves to create images of the inside of your body. Ultrasound images can show body parts, organs and blood flow. There is no radiation used in ultrasound.

During your ultrasound, a sonographer (ultrasound technician) will apply a water-based gel to the area that is being examined. The technician will press the probe firmly against your skin and glide it over the area several times.

We offer the following types of ultrasound:

  • Obstetrical ultrasound
  • Abdominal ultrasound
  • Pelvic (non-pregnant) ultrasound
  • Carotid, jugular or vertebral ultrasound
  • Peripheral venous ultrasound
  • Penile ultrasound (with/without injection)
  • Scrotal ultrasound
  • Transrectal ultrasound
  • Transvaginal ultrasound

Your appointment

  • Please arrive 15 minutes before your appointment. If you’re late, your appointment may be rescheduled.
  • Bring a bag for your personal belongings during the exam.
  • Please see below for specific preparation instructions dependent on the type of ultrasound. You should also follow any instructions given to you by your doctor or when you booked the ultrasound.
  • The length of your appointment will depend on what kind of ultrasound you are having. Ultrasounds can vary from 30 minutes to 60 minutes, depending on complexity of the procedure.
  • We do our best to stay on time. Unfortunately, your appointment may be delayed by unforeseen circumstances. We recommend that you come prepared for delays.
  • If you wish to have a doctor other than your referring doctor copied on the results report, please let the receptionist know before your test.

A report will be sent to your doctor(s) within 10 days.


Types of ultrasounds

An abdominal ultrasound is used to assess organs and other structures in the abdomen, including the liver, gallbladder, pancreas, bile ducts, spleen and abdominal aorta.

If your appointment is in the morning, do not eat or drink after midnight. You may drink enough water to take any necessary medications.

If your appointment is in the afternoon, eat a light breakfast at 7 a.m. that is fat-free and dairy-free (such as dry toast and a clear beverage such as water or apple juice).  Do not have anything else to eat or drink until after your test is done. This is especially important if you are a diabetic.
