Ultrasound

Ultrasound

Ultrasound is an imaging technique that uses sound waves to view soft-tissue organs within the body. The Sonographer is the imaging specialist and the Radiologist interprets the results.

An ultrasound study begins by applying a water-soluble gel to the appropriate part of the body, enabling transmission of sound waves from a transducer (or camera) as it moves across the patient's skin.

There are no known side effects from ultrasound and this is why it is an excellent tool to image the fetus. Obstetrical ultrasound makes up a large portion of our work, in addition to investigations of the abdomen and other soft tissue organs. Ultrasound can also be used to assist with various types of biopsies, as well as imaging blood vessels and analyzing blood flow.

Three of the most common ultrasound procedures are abdominal and pelvic ultrasound, obstetrical and pelvic ultrasound and renal ultrasound (kidney and bladder). SFMH also provides Echocardiography which is an ultrasound of the heart.

If your Doctor wants you to have an Ultrasound:

  • You require a requisition form from your doctor we must recieve this and it will be reviewed before an appointment is given. 

Unless you are sent from the Emergency Department you must have an appointment, which is usually arranged by your doctor’s office.

When you arrive, please report to the Hospital Registration/Information Office in the SFMH lobby. Be prepared to present your Health Card.

If you are unable to keep your appointment, notify the Diagnostic Imaging Department as soon as possible – preferably 24 hours in advance. 

Visiting or accompanying patients

Children (12 and under) should not accompany the patient to any ultrasound appointment, as we cannot provide for their supervision while completing your test or treatment

In the case of an obstetrical ultrasound, which we try to make a warm bonding event, we invite you to include one other person you may wish to share this moment with. They are welcome into the room after the diagnostic portion of the ultrasound is complete. 

Please note it is the policy of St. Francis Memorial Hospital that all patients and visitors are prohibited from using their cell phones during imaging exams as well as taking photographs, videos or voice recordings of our patients or of our staff.

What you should know

When you come to the hospital, please arrive 15 minutes early to register at the Diagnostic Imaging Reception Desk. Bring your health card and your requisition, which gives our sonographers and radiologists the information they need to perform the correct study optimally for you.

Abdominal Ultrasound - FAQ's

What is an Abdominal Ultrasound?

During an Abdominal Ultrasound we may assess the anatomical integrity of a number of different soft-tissue organs, including the liver, gallbladder, kidneys, pancreas, spleen and major veins and arteries. An Abdominal ultrasound encompasses the area below the lung and to the approximate area of the belly button.

What do I need to do before an Abdominal  ultrasound?

Have nothing to eat or drink for eight hours prior to your appointment (Please take necessary medication using a small amount of water)   For children under three years, feed as usual. 

Your empty stomach is much less gaseous than it is after you've eaten.  An empty stomach results in a much more clear image for the radiologist and doctor to work with in assessing your needed care. An empty stomach also helps us adequately visualize the gall bladder, which contracts when a person eats.  

Eating even a small amount of food may effect the quality of the study being done, espcially when examining the liver and gallbladder- if you are diabetic please avoid food that have fat in them if you eat something to regulate your blood sugars.  If you are an insulin-dependent diabetic and are asked to miss breakfast, take half your normal dose of insulin. Ifyou have to miss any other meal, contact your doctor for further instructions.

Abdominal and Pelvic Ultrasound- FAQs

Before the Exam:

Do not eat.   Empty your bladder first and then drink drinking 3-4 full 8 oz glasses (aprox 1 liter) of clear fluid -preferably water-- this must be completed one hour before your appointment time. Do not empty your bladder after drinking the water until after your test. If your bladder becomes too uncomfortable, you may pass a small amount of urine to relieve the pressure. If your bladder is not full at the time of your test you may have to reschedule.

If you need to take medication, take it with a small amount of water. If you are an insulin-dependent diabetic and are asked to miss breakfast, take half your normal dose of insulin. If you have to miss any other meal, contact your doctor for further instructions.

Obstetrical Ultrasound - FAQ's

What is an Obstetrical Exam?

During an Obstetrical and Pelvic Ultrasound we may include the following in our assessment: gestational age, placental position, appropriate growth indices, fetal anatomy and fetal well-being.

What do I need to do before the ultrasound?

For obstetrical examinations before 12 weeks, or for pelvic ultrasound, a full bladder is necessary. The pelvic organs are situated behind the urinary bladder, and when full it acts as a window for the sound waves.

Empty your bladder first and then drinking four full 8 oz glasses of clear fluid  at least one hour prior to your appointment.  Do not empty your bladder after drinking the fluids until completion of the exam - a washroom is close by the examining room, you will be asked to empty your bladder after the first pictures are taken of your bladder. 

For obstetrical examinations later than 12 weeks, a full bladder is not necessary. No special preparation is required. Some examinations include a transvaginal ultrasound, where we insert a thin probe into the vagina to allow better visualization of the anatomy. Patients are able to void prior to this procedure.

Renal Ultrasound (Kidney and Bladder) - FAQ's

What do I need to do before Renal/KUB ultrasound?

Before the Exam:

Do not eat.   Empty your bladder first and then drink drinking 3-4 full 8 oz glasses (aprox 1 liter) of clear fluid -preferably water-- this must be completed one hour before your appointment time. Do not empty your bladder after drinking the water until after your test.  If your bladder becomes too uncomfortable, you may pass a small amount of urine to relieve the pressure. If your bladder is not full at the time of your test you may have to reschedule.

If you need to take medication, take it with a small amount of water. If you are an insulin-dependent diabetic and are asked to miss breakfast, take half your normal dose of insulin. If you have to miss any other meal, contact your doctor for further instructions.
