Ultrasound

Ultrasound uses high-frequency sound waves to look at organs and structures inside the body. During pregnancy, doctors use ultrasound tests to examine the baby. Unlike an X-ray, an ultrasound does not involve exposure to radiation.

How the test is performed

The ultrasound technician will position you on the table, apply gel on your skin (over the area being imaged), and then press on the skin with a hand-held transducer to obtain the necessary images.

How to prepare for the test 

Preparation varies by type of ultrasound. It is very important for you to know whether you should eat or drink before the test:

  • Abdominal ultrasound (liver, bile ducts, spleen, pancreas, gallbladder, aorta)  – Do not eat or drink for six hours prior to the test. Medications may be taken with water.
  • Abdominal and pelvic ultrasound – You may not eat for six hours prior to the test but you must arrive with a full bladder. Finish drinking 1 litre (36 ounces) of water one hour before your appointment.
  • Pelvic ultrasound (including transvaginal) – You must arrive with a full bladder. Finish drinking 1 litre (36 ounces) of water one hour before your appointment.
  • Pregnancy ultrasound –You must arrive with a full bladder. Finish drinking 1 litre (36 oz.) of water one hour before your appointment.
  • Prostate ultrasound – You must arrive with a full bladder. Finish drinking 1 litre (36 ounces) of water one hour before your appointment.
  • Renal ultrasound (kidneys, ureters, bladder) – You may not eat for six hours prior to the test but you must arrive with a full bladder. Finish drinking 1 litre (36 ounces) of water one hour before your appointment. Medications may be taken with water.
  • Other – no preparation required.

How the test will feel

Most ultrasound examinations are quick and painless. If you are having a pelvic or endovaginal ultrasound you may have some discomfort because of the fullness of your bladder.

"After three months of convalescent care at KDH, my wife and I wanted to take a moment to express our sincere gratitude and appreciation for all the care staff who attended to me during my stay. From the moment I arrived at the unit, I was struck by the welcoming and compassionate atmosphere. I would like to extend a special thank you to every member of the care staff for your helpfulness and kindness. You all played an important role in aiding my recovery, not just physically but also emotionally. What sets this convalescent unit apart is the genuine care and concern shown towards residents. I never once felt like just a bed number but rather an individual who was valued and respected. The encouragement given to residents to improve their health and engage in social activities also greatly enriched my experience. I made new friends and created lasting memories. I cannot thank you enough for your unwavering support. I will always remember my time there with fondness, thanks to the wonderful care staff who made it a home away from home. Thank you for everything."
