Abdominal Ultrasound
Ultrasound imaging, also called ultrasound scanning or sonography, involves the use of a small transducer (probe) and ultrasound gel to expose the body to high -Frequency sound waves. Ultrasound is safe and painless, and produces pictures of the inside of the body using sound waves. Ultrasound examinations do not use Ionizing radiation (as used in x-rays). Because ultrasound images are captured in real-time, they can show the structure and movement of the body's internal organs, As well as blood flowing through blood vessels.
Conventional ultrasound displays the images in thin, flat sections of the body. Advancements in ultrasound technology include three-dimensional (3-D) ultrasound that formats the sound wave data into 3-D images. Four-dimensional (4-D) ultrasound is 3-D ultrasound in motion.
Doppler ultrasound is a special ultrasound technique that evaluates blood flow through a blood vessel, including the body's major arteries and veins in the abdomen, Arms, legs and neck.
Why should I do it ?
- Abdominal ultrasound imaging is performed to evaluate the:
- Kidneys
- Liver
- Gallbladder
- bile ducts
- pancreas
- spleen
- abdominal aorta and other blood vessels of the abdomen
-
Ultrasound is used to help diagnose a variety of conditions, such as:
- abdominal pain or distention (enlargement(
- abnormal liver function
- enlarged abdominal organ
- kidney stones
- gallstones
- an abdominal aortic aneurysm
- Additionally, ultrasound may be used to provide guidance for biopsies.
Any preparations needed?
- You should wear comfortable, loose-fitting clothing.
- You may need to remove all clothing and jewelry in the area to be examined.
- Other preparation depends on the type of examination you will have. For some scans your doctor may instruct you not to eat or drink for as many as 12 hours before your appointment. For others you may be asked to drink up to six glasses of water two hours prior to your exam and avoid urinating so that your bladder is full when the scan begins.
- In case of children, ultrasound examinations are very sensitive to motion, and an active or crying child will slow the examination process. To ensure a smooth experience, it would be beneficial to explain the procedure to the child prior to the exam.
- For a study of the liver, gallbladder, spleen, and pancreas, you may be asked to eat a fat-free meal on the evening before the test and then to avoid eating for eight to 12 hours before the test.
- For ultrasound of the kidneys, you may be asked to drink four to six glasses of liquid about an hour before the test to fill your bladder. You may be asked to avoid eating for eight to 12 hours before the test to avoid gas buildup in the intestines.
