CT Scan of the Pancreas
Computed tomography (CT) scan is a noninvasive diagnostic imaging procedure that uses a combination of X-rays and computer technology to produce horizontal, or axial, images (often called slices) of the body. A CT scan shows detailed images of any part of the body, including the bones, muscles, fat, and organs. CT scans are more detailed than standard X-rays ....!
CT scans of the pancreas can provide more detailed information about the pancreas than standard X-rays of the abdomen, thus providing more information related to injuries and/or diseases of the pancreas. CT scans of the pancreas are useful in the diagnosis for the cancer of the Pancreas and Pancreatitis..!
Pancreatitis is the inflammation and autodigestion of the pancreas. Autodigestion describes a process whereby pancreatic enzymes destroy its own tissue leading to inflammation. The inflammation may be sudden (acute) or ongoing (chronic). Acute pancreatitis usually involves a single "attack," after which the pancreas returns to normal. Severe acute pancreatitis can be life threatening. In chronic pancreatitis, permanent damage occurs to the pancreas and its function, often leading to fibrosis (scarring)...!
The most common causes of pancreatitis include the following:
· Gallstones that block the pancreatic duct
· Alcohol abuse, which can lead to blockage of the small pancreatic ductules
· Other causes of pancreatitis include the following:
· Abdominal trauma or surgery
· Kidney failure
· Infections, such as mumps, hepatitis A or B, or salmonella
· Cystic fibrosis
· Presence of a tumor.............................................................
The pancreas is made up of 2 types of glands:
· Exocrine.The exocrine gland secretes digestive enzymes into the duodenum. These enzymes are secreted into a network of ducts that join the main pancreatic duct, which runs the length of the pancreas.
· Endocrine.The endocrine gland, which consists of the islets of Langerhans, secretes hormones into the bloodstream.
The reasons for a CT scan of the pancreas
A CT scan of the pancreas may be performed to assess the pancreas for tumors and other lesions, injuries, bleeding, infections, abscesses, unexplained abdominal pain, obstructions, or other conditions, particularly when another type of examination, such as X-rays or physical examination, is not conclusive.
CT scans of the pancreas may be used to distinguish between disorders of the pancreas and disorders of the retroperitoneum (the back portion of the abdomen behind the peritoneal membrane).
There may be other reasons for your doctor to recommend a CT scan of the pancreas.
