Ultrasound is a type of scanning technique that uses high-frequency sound waves to produce images of structures inside the body. It is also known as sonography or medical sonography.
When it’s done:
Ultrasound is recommended depending on the symptoms and for:
- The assessment of a breast lump
- The assessment of the foetus inside the uterus during pregnancy
- The evaluation of the thyroid gland
- The diagnosis of cancer
- The diagnosis of infections
- The diagnosis of a gallbladder disease
- Assessing abnormalities of muscles and tendons
When to Avoid:
There is no specific condition when this scan should be avoided.
How to prepare:
Most of the times, no special preparation is required and it depends on which area of your body needs to be examined.
Gallbladder Examination: Avoid eating and drinking for up to 6 hours before the test.
Pelvic Ultrasound: Drink lots of water and do not urinate before the scan is performed, which allows for the better visualisation of the uterus, ovaries or the prostate.
