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]
Biliary sludge has been associated with pregnancy, rapid weight loss, total parenteral nutrition, drugs such as ceftriaxone and octreotide, solid organ transplantation, and gastric surgery. [1] [2] In many of these conditions, it is thought that the impairment in the contractility of the gallbladder leads to the formation of the sludge. [2]
Oral cholecystography is a radiological procedure used to visualize the gallbladder and biliary channels, developed in 1924 by American surgeons Evarts Ambrose Graham and Warren Henry Cole. It is usually indicated in cases of suspected gallbladder disease, and can also be used to determine or rule out the presence of intermittent obstruction of ...
[1] [2] Cholescintigraphic scanning is a nuclear medicine procedure to evaluate the health and function of the gallbladder and biliary system. A radioactive tracer is injected through any accessible vein and then allowed to circulate to the liver, where it is excreted into the bile ducts and stored by the gallbladder [3] until released into the ...
Other procedures associated with ERCP include the trawling of the common bile duct with a basket or balloon to remove gallstones and the insertion of a plastic stent to assist the drainage of bile. [11] Also, the pancreatic duct can be cannulated and stents be inserted. The pancreatic duct requires visualisation in cases of pancreatitis.
There are at least four types of cholangiography: [citation needed] Percutaneous transhepatic cholangiography (PTC): Examination of liver and bile ducts by x-rays. This is accomplished by the insertion of a thin needle into the liver carrying a contrast medium to help to see blockage in liver and bile ducts.
Biliary colic, also known as symptomatic cholelithiasis, a gallbladder attack or gallstone attack, is when a colic (sudden pain) occurs due to a gallstone temporarily blocking the cystic duct. [1] Typically, the pain is in the right upper part of the abdomen , and can be severe. [ 2 ]
Ryan Brunsing, director of MRI at Stanford Health Care, says he supports whole-body MRI screening “both for its current uses and its potential as MRI technology continues to improve.”
