An obstetric ultrasound is a very safe and accurate investigation of your unborn baby. Ultrasound uses harmless high frequency inaudible sound waves to obtain images. Ultrasound waves are not dangerous or irritating for you or your baby.
Obstetric ultrasounds require you to have a full bladder. It is necessary to drink 800ml-1L of water one hour prior to the scan and refrain from going to the toilet. In some instances an internal ultrasound is required and is performed with an empty bladder. The sonographer will discuss this option with you.
The ultrasound waves are transmitted and collected via a hand held probe which is moved over the part of the body being investigated. You will not feel any pain or discomfort. Your procedure will usually take between 30 and 45 minutes. A highly trained sonographer will conduct the study.
After the procedure the results will be reported by our radiologist, Dr. Himanshu Kaushik. You may wait while the images are prepared and reported or you can organise an appropriate time to pick up your results before your next appointment with your GP or specialist. They can also be provided via electronic transfer to your referring practitioner if requested. Comprehensive Medical Imaging strongly advises that you return to your referring doctor, in order for your doctor to discuss your report with you.
Why has my doctor requested an ultrasound?
Ultrasound is a non-invasive investigation to assist in monitoring your pregnancy. This examination may provide valuable information about your pregnancy that will assist the doctor in ensuring a successful outcome for you and your baby.
There are many reasons a doctor may request an ultrasound. Some of these are:
To assist in determining the gestational age (when the baby is due).
To assess the growth of a baby.
To assess the number of babies.
To check for possible abnormalities.
To follow-up on any bleeding during the pregnancy.
What is the difference between a Nuchal Translucency scan and an Obstetric Ultrasound?
A Nuchal Translucency scan is an ultrasound usually performed between 11th to 13th week of pregnancy. It is a screening process (ultrasound and blood test) to assess the risk for your baby of certain chromosomal abnormalities, including Down Syndrome. For more detailed information please see our Nuchal Translucency section.
Can I eat before having an obstetric ultrasound?
You can eat before your ultrasound. You are required to have a full bladder. It is necessary to drink 600-800ml of water two hours prior to the scan and refrain from going to the toilet before the scan.
Can I have a female sonographer/technician to perform the scan?
Yes, please let reception know when making your appointment. We have female radiographers and sonographers sensitive to the needs of female patients.
Is this test safe for my baby?
Ultrasound is a very safe and accurate investigative tool used to assess many organs in the body. Ultrasound uses harmless high frequency inaudible sound waves to obtain images. Ultrasound waves are not dangerous or irritating to adults or children. There is NO radiation with an ultrasound examination.
Will the sonographer performing my scan tell me what’s wrong?
It is the sonographer’s duty to perform the test and ensure the images are of high quality for the radiologist (specialist doctor) to interpret them.
