MRCP makes use of heavily T2-weighted MRI pulse sequences. [3] [7] These sequences show high signal in static or slow moving fluids within the gallbladder, biliary ducts and pancreatic duct, with low signal of surrounding tissue. Secretin is also given to a patient to increase ductal compliance, making imaging easier. [3]
Autoimmune Pancreatitis; Other names: AIP: A. Axial CT image in the pancreatic parenchymal phase shows the typical enlarged, poorly enhancing gland. B. Coronal T2 Weighted MR image demonstrates low signal intensity in the pancreas due to the diffuse fibrosis in the gland.
Options for medical imaging in pregnancy include the following: Magnetic resonance imaging (MRI) without MRI contrast agents as well as obstetric ultrasonography are not associated with any risk for the mother or the fetus and are the imaging techniques of choice for pregnant women. [1]
New cases of chronic pancreatitis develop in about 8 per 100,000 people a year and currently affect about 50 per 100,000 people in the United States. [10] It is more common in men than women. [1] Often chronic pancreatitis starts between the ages of 30 and 40 and is rare in children. [1]
Acute pancreatitis (AP) is a sudden inflammation of the pancreas.Causes include a gallstone impacted in the common bile duct or the pancreatic duct, heavy alcohol use, systemic disease, trauma, elevated calcium levels, hypertriglyceridemia (with triglycerides usually being very elevated, over 1000 mg/dL), certain medications, hereditary causes and, in children, mumps.
Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to generate pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields , magnetic field gradients, and radio waves to form images of the organs in the body.
It is named for gynecologist Thomas Stephen Cullen (1869–1953), [1] who first described the sign in ruptured ectopic pregnancy in 1916. [ 2 ] This sign takes 24–48 hours to appear and can predict acute pancreatitis , with mortality rising from 8–10% to 40%.
Chronic pancreatitis is a long-standing inflammation of the pancreas that alters the organ's normal structure and functions. [1] It can present as episodes of acute inflammation in a previously injured pancreas , or as chronic damage with persistent pain or malabsorption .
