<prompt> Which of the following is true regarding the principle of use of MRCPIntra liminal dye is used to create the three dimension view of the structuresDye is instilled percutaneously first then MRI is usedUse of heavily T2-weighted image without contrast to create the three dimensional image of the biliary tree using MIP algorithmUse of systemic Gadolinium as a contrast agent to create the three dimensional image of the biliary tree  <response>: MRI cholangiography and MRI cholangiopancreaticography MRCP are imaging techniques used to evaluate the biliary system. Heavily T2- weighted images are used to provide an overview of the biliary system and pancreatic duct Excellent diagnostic - quality images are obtainable, with high sensitivity and specificity for evaluation of biliary duct dilation, strictures and intra ductal abnormalities Ref: Blumga surgery of liver, biliary tract and pancreas 5th edition Pgno : 315
