About this scan
Ultrasound imaging uses high-frequency sound waves to create real-time images of the body's internal structures. Unlike MRI and CT, there is no ionising radiation, making it the preferred choice for assessing abdominal organs, pelvic structures, vascular blood flow, and soft tissue masses.
A sonographer applies a small amount of gel to the skin and moves a transducer (probe) over the area. The sound waves bounce back from internal structures to create live images on screen. Most ultrasound scans are painless and take 20–40 minutes. Results are often available immediately, with a written radiologist report typically within 24 hours.
Key facts
The process
The sonographer confirms you've followed any required preparation (fasting, full bladder) and explains the procedure.
A warm gel is applied to the skin. The sonographer gently moves the probe over the area, taking measurements and recording images.
The sonographer may share initial findings with you during the scan. The scan typically takes 20–40 minutes.
A consultant radiologist reviews the images and your written report is delivered to your ScanBook portal within 24 hours.
Before your scan
For abdominal scans: fast (no food or drink except water) for 4–6 hours before your appointment.
For pelvic scans: arrive with a full bladder; drink 1 litre of water 1 hour before and don't urinate.
For thyroid, breast, MSK and vascular scans: no preparation is needed.
Wear loose, comfortable clothing to allow easy access to the area being scanned.
FAQs
Is any preparation needed for a thyroid ultrasound?
No preparation is needed. Wear clothing that allows easy access to the neck. The scan is painless and takes approximately 20 minutes.
Can a thyroid ultrasound diagnose thyroid cancer?
Ultrasound cannot definitively diagnose thyroid cancer, but it can identify high-risk features in nodules that warrant further investigation, such as fine needle aspiration (FNA) biopsy. The TIRADS classification system is used to risk-stratify nodules.
Why do I need an ultrasound if my blood tests are normal?
Thyroid blood tests measure hormone levels, not structure. Nodules, cysts and goitre can be present with entirely normal thyroid function tests. Ultrasound is the only way to assess the physical structure of the gland.
Is ultrasound safe?
Yes. Ultrasound uses sound waves, not radiation, and is completely safe for all patients, including pregnant women and children.
Will I need a full bladder?
Only for pelvic and lower abdominal scans. A full bladder creates an acoustic window for better imaging. For abdominal, thyroid, breast and MSK scans, no bladder preparation is needed.
Can ultrasound detect cancer?
Ultrasound can identify suspicious masses, cysts and structural abnormalities that may require further investigation. It's commonly used to characterise lesions found on physical examination or other imaging.
