What is a linear EUS?
Linear EUS provides a localised oblique image parallel to the scope and enables therapeutic intervention under ultrasound (Fig 3). High frequency EUS mini-probes are also available which can be passed down a standard biopsy channel of an endoscope in cases where strictures cannot be passed using a standard EUS scope.
What is an EUS scope?
Endoscopic ultrasound (EUS) is a minimally invasive procedure to assess digestive (gastrointestinal) and lung diseases. A special endoscope uses high-frequency sound waves to produce detailed images of the lining and walls of your digestive tract and chest, nearby organs such as the pancreas and liver, and lymph nodes.
What is the difference between endoscopy and EUS?
An endoscopic ultrasound (EUS) is a specialized procedure that blends: Endoscopy — use of a scope to look at the inside lining of the gastrointestinal (GI) tract. Ultrasound — use of high frequency sound waves to see detailed images of the bowel wall and nearby organs or structures.
What is linear Echoendoscope?
The linear echoendoscope has an oblique endoscopic view. Hence, the process of pharyngeal intubation is almost blind, similar to the process of insertion of a duodenoscope. The echoendoscope is inserted into the pharynx with the tip deflected downward and the left-right control fixed in the neutral position.

How much does an EUS scope cost?
On MDsave, the cost of an EGD with EUS ranges from $2,513 to $3,501. Those on high deductible health plans or without insurance can save when they buy their procedure upfront through MDsave. Read more about how MDsave works.
Is EUS painful?
An EUS does not usually hurt but it can be a little uncomfortable, particularly when you first swallow the endoscope.
Why would a doctor order an EUS?
EUS is ordered to get a more detailed examination of your digestive tract, including your esophagus, stomach, colon, and rectum, and for organs near the digestive tract, including the pancreas, liver, and gall bladder. It can help your doctor diagnose causes of abdominal pain or abnormal weight loss.
What is linear scope?
In the linear array images, one wall of the esophagus is seen and the hypoechoic linear structure is parallel to the axis of the scope. A needle can be passed through the accessory channel of the endoscope and visualized in real time as it is directed through the esophageal wall and into lesions.
How long does an EUS take?
EUS uses a special endoscope with an ultrasound probe attached. Our doctors use EUS to evaluate and diagnose upper and lower digestive tract disorders. EUS takes approximately one to two hours and you can return home when it is finished.

What are the different types of EUS scopes?
There are two types of EUS scopes: radial scanning and linear array. The radial type scans in a plane perpendicular to the axis of the scope to produce 360˚ images similar to a CT “slice.” The transducer appears as a “bull’s-eye” within the image. The linear array type scans in a plane parallel to the axis of the scope. It is therapeutic in nature.
How are linear EUS used in the endoscope?
Linear EUS In the linear array images, one wall of the esophagus is seen and the hypoechoic linear structure is parallel to the axis of the scope. A needle can be passed through the accessory channel of the endoscope and visualized in real time as it is directed through the esophageal wall and into lesions.
When to use a linear scope in endoscopy?
Linear scopes were introduced later, to allow therapeutic devices, so physicians who trained on linear scopes tend to start with them. EUS is used to further investigate lesions, masses, and cysts that have been found during a routine endoscopy, conventional ultrasound, CT scan or MRI.
What does an ultrasound look like with a linear scope?
The linear scope gives a 90′ wedge-shaped image. Echo-tipped flexible needles can be passed through the scope to perform ultrasound-guided fine needle aspirations and core biopsies. The image using a linear scope looks like this:
