An ultrasound scan usually takes around 10–15 minutes, but the duration can vary depending on the specific type of ultrasound being performed.
You can use the following tips to prepare for an ultrasound scan:
- Wear loose-fitting clothes that can be exposed in the midsection.
- Fill your bladder before the test by drinking water unless advised otherwise.
- For some scans, a period of fasting is necessary.
- Remove extra jewelry and accessories.
- Follow the instructions of the radiologists as they perform the scan.
Ultrasound is not harmful in pregnancy because it uses high-frequency sound waves to visualize soft tissues and fluids in the body, not harmful ionizing radiation.
For an ultrasound scan, you are made to lie on the examination table and expose the part for the scan. A cold gel is put over the part that needs to be examined. The ultrasound probe is then moved over that part by the radiologist at different angles and positions to get various views of the organ. For a better view via the probe or transducer, they might ask you to turn to your side or move your limb. Once the scan is done, the gel is wiped with tissue, and then you can proceed to move out of the examination cubicle.
No, fasting is not necessary for most ultrasound scans. However, for certain types such as abdominal ultrasounds, your doctor may advise fasting for a few hours to obtain clearer organ images.
