What is MRCP - Biliary System MR Cholangiography?

Magnetic resonance cholangiopancreatography (MRCP) is a non-invasive MR imaging technique that produces high-resolution images of the biliary tree and pancreatic ducts using heavily T2-weighted sequences. Stationary fluid (bile, pancreatic juice) appears bright while surrounding tissues are suppressed.

MRCP is the imaging gold standard for diagnostic evaluation of biliary obstruction, choledocholithiasis, primary sclerosing cholangitis (PSC), choledochal cysts, biliary anatomic variants and chronic pancreatitis. It avoids ionizing radiation, contrast and procedural complications of ERCP, which is now reserved for therapeutic interventions.

Symptoms

Suspected choledocholithiasis with intermediate probability
Painless jaundice for malignancy workup
Recurrent cholangitis evaluation
Primary sclerosing cholangitis monitoring
Pancreatic ductal anomaly assessment (pancreas divisum)
Choledochal cyst suspicion
Post-cholecystectomy biliary stricture or leak

Risk Factors

Pacemaker or non-MR-conditional implants
Severe claustrophobia
Pregnancy (relative, no contrast in first trimester)
Severe renal impairment if gadolinium needed
Inability to lie still
Recent gastrointestinal contrast (artifact)
Significant ascites or large body habitus

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • Persistent right upper quadrant pain with elevated LFTs
  • Suspected biliary obstruction with normal ultrasound
  • Pre-ERCP planning for therapeutic intervention
  • Recurrent pancreatitis without identified cause
  • Suspected primary sclerosing cholangitis
  • Postoperative biliary leak or stricture suspicion

Treatment Methods

01
Patient fasting 4-6 hours to reduce duodenal motion
02
Antiperistaltic agent (glucagon, hyoscine) optional
03
Heavily T2-weighted single-shot fast spin echo sequences
04
Thin-section axial and coronal acquisitions
05
3D maximum intensity projection reconstruction
06
Optional secretin-stimulated MRCP for pancreatic disease
07
Optional gadoxetate-enhanced MR for hepatocyte imaging
08
Reading by abdominal radiologist with biliary expertise
09
Therapeutic ERCP based on findings if obstruction confirmed
