What is an Ultrasound?
Ultrasound is a medical diagnostic modality which utilizes soundwaves to acquire information. It is a readily accessible, painless tool that can be used to detect many abnormalities without using ionizing radiation. Its applications are varied and multiple, ranging from general abdominal scans, to vascular, musculoskeletal, gynaecological and obstetric examinations.
What is Colour Doppler ultrasound?
This is a specialised ultrasound examination studying blood flow within the body. It can assist doctors to assess the blood flow through arteries and veins.
Arriving with adequate preparation
Certain ultrasound examinations require appropriate preparation prior to your appointment to ensure optimal assessment of various anatomic structures. For example, you will be requested to fast for a minimum of 6 hours prior to an abdominal examination to allow the gallbladder to be adequately visualised for the assessment of certain pathology such as stones or polyps. Failure to fast adequately in this case will result in a contracted gallbladder and subsequently result in a suboptimal examination.
Our receptionist will inform you at the time of booking of any preparations that may be required.
Q1: Why have I been asked to drink a litre of water for my pelvic/renal ultrasound?
A: A comfortably full bladder is required to provide a uniform acoustic window for an optimal assessment of the pelvic structures.
Q2: What is the preparation for a pelvic/renal ultrasound?
A: You will need to empty your bladder an hour and a half before the examination. Then, drink between 600mL to one litre of water within the next half hour and hold. Arrive with a comfortably full bladder. You will be asked to empty the bladder as part of the examination so it is important to hold a tolerable amount.
Q3: How long does an examination typically take?
A: Please allow approximately 30 minutes for each appointment although certain examinations such as morphology (obstetrics) or vascular examinations such as leg arteries or varicose veins require 45 minute appointments.
Please ensure to arrive 10-15 minutes prior to your appointment time for registration of your details.
