How is a pancreatic ultrasound used to diagnose pancreatic cancer?
A Pancreatic Ultrasound may help diagnose (find): An ultrasound of the pancreas is viewed through an abdominal ultrasound, which is requested by a physician if the patient's abdominal symptoms are not clear. An ultrasound of the pancreas can detect an enlarged pancreas. A pancreatic ultrasound is sometimes used to diagnose pancreatic cancer.
What are the imaging challenges of the pancreas?
In spite of the progress of imaging techniques, the differential diagnosis of focal solid lesions remains the prime problem of imaging examinations of the pancreas. The major aim of the ultrasound examination is early detection of pancreatic neoplasm.
Can the pancreas be seen through duodenum?
The uncinate and head of the gland may also be imaged through the duodenum. As the pancreas abuts the stomach and duodenum, upper endoscopic ultrasound is an ideal modality for precise investigation of the gland.

Ultrasound scans use high frequency sound waves to create a picture of a part of the body. An abdominal ultrasound scan shows up blood flow and changes in your tummy (abdomen), including abnormal growths.
How does pancreatitis appear on ultrasound?
Abdominal Ultrasound An ultrasound may reveal a dilated bile duct, which may indicate a blockage—a common cause of acute pancreatitis.
How do you examine your pancreas?
Your doctor inserts an endoscope—a thin, flexible tube—down your throat, through your stomach, and into your small intestine. The doctor turns on an ultrasound attachment to create pictures of your pancreas and bile ducts. Your doctor may send you to a gastroenterologist to perform this test.
What is endoscopic ultrasound pancreas?
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.
Where is the pancreas?
The pancreas is part of the digestive system. The pancreas is quite high up in your abdomen. It lies across your body where your ribs meet at the bottom of your breastbone, just behind your stomach. It is about 6 inches (15 centimetres) long and shaped like a leaf.

Preparation for pancreatic ultrasound
Preparation for pancreatic ultrasound should begin 48 hours before the scheduled visit to the clinic. It is necessary to give up food that can provoke the formation of gases in the intestines. As a preparation for pancreatic ultrasound, doctors strongly recommend giving up vegetables, black bread, dairy and fermented milk products.
Methods of diagnostics
Pancreatic ultrasound is performed using sensors with a frequency of 2-7 MHz. Visualization of the departments of organs is carried out polypositionally, that is, a person is located on the left, right side, on the back.
Transcript of the results
Normally, the echostructure of the organ is homogeneous. The echogenicity of the gland is slightly increased, its contours are even.
Additional data
To establish a diagnosis, it is important not only to determine deviations from the norm of the size of the pancreas by ultrasound, but also to conduct a biochemical blood test.
Why is the pancreas difficult to examine?

What is ultrasound in pancreas?
Contemporary imaging techniques, ultrasound (US) being one of them, have contribute d to a considerable progress in the diagnosis of pathological changes located in the region of the pancreas. In US examination, one should assess the echogenicity, echostructure, size and shape (outlines) of the pancreas. It is possible to detect diffuse (encompassing the whole parenchyma or its large fragments) or focal lesions, including solid and cystic ones. They correspond to inflammatory, post-inflammatory and neoplastic changes. US examination aims at the differentiation of these pathologies and specification of their character(1, 2).
Why is the pancreas not easy to test?
First of all, this is because of its structure, which is quite complex, and proximity of other anatomical structures. The head of the pancreas is surrounded by the duodenal loop and is localized to the right of the mesenteric vessels and mesenteric-portal confluence. The inferior aspect of the head, called the uncinate process is located to the right of the isthmus of the pancreas which joins the head with the body. The tail of the pancreas rises upwards and reaches the splenic hilum. The anterior surface of the pancreas is at the right side adjacent to the transverse colon and, further, to the stomach. Its superior margin borders the coeliac trunk and the splenic artery which originates from the coeliac trunk(2, 3).
What are the errors in the assessment of the pancreas belonging to this group?
The errors in the assessment of the pancreas belonging to this group may result from the contiguity of the caudate lobe of the liver and other organs or intestinal loops that surround the head of the pancreas, the presence of the vessels and bile ducts as well as lymph nodes in the vicinity of the gland.
Why are there diagnostic errors in the pancreas?
The diagnostic errors may result from the lack of a pancreatic capsule (an evident separation from adjacent organs), its anatomical structure and possible anatomical variants as well as from its echostructure and echogenicity.
Where is the pancreas located?
Moreover, the pancreas is a large organ located deep in the abdominal cavity in the extraperitoneal space and does not have its own capsule. On examination, it may become covered by the intestine or stomach, which contain air that inhibits adequate assessment(4, 5). Such a situation occurs especially in the course of acute inflammations of abdominal organs and the pancreas as well as during paralytic ileus or postoperative conditions. Below, the most common mistakes in ultrasound imaging of the pancreas are presented and divided into three groups:
Why is the US probe placed in several planes?
In such cases, the US probe should be placed in several planes in order to reveal the connection in the region of inferior poles of the kidneys(5).
