What is Ultrasound?
Ultrasound is an imaging tool that uses sound waves to make an image. Ultrasound does not use radiation. It is used to evaluate a body part or organ like the liver, gallbladder, pancreas, kidneys, and several other body parts. It is also used to evaluate veins and arteries for blood clots.
This is also a great imaging tool to evaluate pregnancy. For ultrasound, the patient lies down on a comfortable exam table and the technologist uses a transducer to scan the body.
For abdominal ultra sounds. NPO after midnight which means nothing to eat or drink after midnight.
For OB/Pregnancy ultrasounds, the patient needs to drink 4 glasses of water I hour prior to the test. This is about 31 ozs. of water. The patient must wait until after the exam to go to the rest room.
