Ultrasound imaging (Sonography) is a method of obtaining real-time images from inside the human through the use of high frequency sound waves. No ionizing radiation (X-rays) or injections are used in ultrasound imaging which makes this modality an extremely safe and painless diagnostic tool.
Common uses of Ultrasound:
- Examination of superficial organs like breast, thyroid and shoulder joints.
- Analysis of abdominal organs (i.e liver, gallbladder, spleen, pancreas, kidneys, bladder) and pelvic organs (i.e prostate, uterus and ovaries).
- To evaluate blood flow and assess for blockage or clots.
- The health and development of the embryo or fetus.
Preparations for Ultrasound:
- For upper abdomen ultrasound of liver and gallbladder, 4-6 hrs fasting is required.
- For Pelvis scan (uterus, ovaries, bladder), a full bladder is required to properly visualize the organs. You may have to drink up to 6 glasses of water and avoid emptying the bladder until the examination is complete.
- Inform the clinic when you make appointment if you are on restricted fluids or suffer from diabetes mellitus.
