Understanding Ultrasound Benefits in Chicago, IL
Ultrasound imaging technology uses sound waves to detect normal and abnormal tissue and structural changes. The sound waves travel through your body and relay images back to a monitor. These images are especially helpful in detecting gastrointestinal problems.
Types of Ultrasound Imaging
Abdominal ultrasound is commonly used by gastroenterologists to detect:
- Gallstones
- Kidney stones
- Tumors and other growths
- Damage to organs
There is another type of ultrasound which uses an endoscope, known as endoscopic ultrasound. This procedure evaluates the digestive system and can be helpful to detect:
- Acid reflux
- Gastroesophageal reflux disease (GERD)
- Cancers, including colon, esophagus, lung, stomach, or pancreas
- Lymphoma
- Pancreatitis
- Bile duct stones
Endoscopic ultrasound also allows the gastroenterologist to take a small sample of tissue for biopsy if necessary.
Why a Gastroenterologist Might Order an Ultrasound
An ultrasound is one of many tools your gastroenterologist may use to determine the cause or extent of:
- A fever
- Blood clots
- Abdominal pain
- Abdominal swelling
- Fluid retention
- Rapid weight loss
- Blood in your stool
What You Need To Do Before an Ultrasound
You may be asked to avoid eating or drinking 6 to 8 hours before the ultrasound. You will also need to remove any jewelry or clothing and wear a cloth or paper robe during your procedure.
What To Expect During an Abdominal Ultrasound
An ultrasound is completely non-invasive. A clear gel is applied to the area which will help conduct the sound waves. A handheld device known as a transducer is then moved across the area. You may need to change position occasionally to achieve a better image. The procedure will take 30 to 60 minutes, depending on the area being viewed.
