MRI M R C P

An MRI MRCP test is a specialized, non-invasive scan used to evaluate the bile and pancreatic ducts using high-resolution magnetic resonance imaging. Without the need for contrast dye, this test provides detailed images of the gallbladder, pancreas, liver, intestines, and biliary tree, helping diagnose conditions like bile duct obstruction, stones, or tumours. 

What is MRI Cholangiopancreatography (MRCP) Test? 

MRI cholangiopancreatography (MRCP) is an advanced imaging technique that uses heavily T2-weighted sequences to highlight fluid-filled structures such as bile and pancreatic ducts. It physiologically reconstructs high-contrast images of the ductal system, making it a non-invasive alternative to traditional ERCP with no radiation or contrast injection.

• T2-weighted axial and coronal sequences 
• 3D thick slab T2 imaging 
• Optional dynamic contrast sequences if clinically warranted 
• Focused hepatobiliary and pancreatic region imaging 

• To non-invasively visualize the bile and pancreatic ducts 
• Detect strictures, stones, or obstructions 
• Formulate surgical or medical intervention plans 
• Monitor post-surgical healing or assess stents 

When and Who Should Get an MRCP MRI Scan? 

Indications for MRI MRCP: 

• Suspected gallstones or bile duct stones 
• Unexplained jaundice 
• Suspected biliary strictures or obstructions 
• Pancreatic duct anomalies or chronic pancreatitis 
• Suspected cholangiocarcinoma (bile duct cancer) 
• Congenital biliary or pancreatic duct conditions 
• Post-ERCP or post-surgical assessment 

Ideal Candidates for MRI MRCP Test: 

• Patients showing unexplained liver function irregularities 
• Individuals with symptoms related to biliary or pancreatic issues 
• Patients unable to undergo ERCP or contrast CT

Benefits of MRI MRCP Test

• No endoscopy or invasive catheterization 
• Completely radiation-free 
• Painless and safe 
• High-quality visualization of the gallbladder and bile ducts 

Conditions Diagnosed Through an MRI MRCP Scan

• Cholelithiasis: Gallstones 
• Choledocholithiasis: Stones in bile ducts 
• Biliary strictures or ductal dilation 
• Pancreatic duct obstructions or cysts 
• Cholangiocarcinoma 
• Congenital abnormalities like pancreas divisum 

• Fast for 4–6 hours prior 
• No special diet or medication changes unless advised 
• Remove all metal accessories or objects 

Pre-requisites for the MRI Cholangiopancreatography MRCP 

• Clinical referral and history from a physician 
• Liver function test reports (optional) 
• Renal function tests if contrast is to be used 

Best Time to Schedule an MRI MRCP Test 

• When ductal pathologies are suspected 
• Pre-surgical evaluation 
• After episodes of pancreatitis or onset of jaundice 

Eligibility & Restrictions for MRI MRCP Scan 

• Safe for children and adults under medical supervision 
• Typically, safe for pregnant individuals 
• Caution in patients with aneurysm clips, pacemakers, or metallic implants 

How Is the MRCP MRI Scan Performed? 

• Patient lies on the MRI table (head-first or feet-first) 
• A surface coil is placed over the abdomen 
• Scan duration: ~20–30 seconds per sequence 
• Patients may be required to hold their breath briefly 
• Most MRCP scans do not require contrast agents 

Cautions During MRI MRCP 

• Patients must remain completely still during the scan 
• Inform the technologist of claustrophobia or uneasiness 
• Declare all surgical history, implants, or allergic conditions
