098105 31897What to Know Before an Ultrasound Scan
Understand common ultrasound preparation instructions and why they can differ according to the body area being examined.
Why does ultrasound preparation vary?
Different examinations require different viewing conditions. For some scans, a fasting period may be recommended. Some pelvic examinations may require a full bladder. Other studies may have little or no preparation.
What should I confirm before arriving?
Ask which examination is being performed, whether you should avoid food or drink, whether you should drink water before the scan, and what time you should arrive. Follow the centre’s instructions rather than using generic advice from the internet.
What happens during an ultrasound?
A sonographer generally applies gel to the skin and uses a handheld transducer to obtain images. The process is typically non-invasive, although some areas may feel mildly uncomfortable when pressure is applied.
What should I bring?
Bring the prescription or referral details and any previous imaging reports that your clinician wants compared. Wear practical clothing that makes access to the examination area easier when appropriate.
How long does it take?
The duration depends on the examination and the number of areas being assessed. The centre can provide the expected timing and preparation instructions when you contact them.
