MR Cholangiopancreatography (MRCP) PROTOCOLS

MR Cholangiopancreatography (MRCP)

  • An imaging technique that aims to replicate the information provided by endoscopic cholangiopancreatography (ERCP) and other cholangiographic techniques by developing very high contrast between fluid (in the ductal anatomy) and background tissues.
  • Best results with extremely T2 weighted long ETL TSE sequences with fat suppression, acquired in a single breath hold.
  • Slices < 4 mm can be processed in a MIP programme to allow some variation of projection
  • Thick slices can provide very fast sequences with a single view and high in-plane resolution

MRCP Parameters 
 

Thick Slice

  • Localiser or simple display of ductal anatomy: 
  • Fat saturated single shot HASTE Axial and oblique coronal planes 
  • TR 2800 TE 1100 ETL 128 Slice thickness 70 mm FOV 300 mm Matrix 256 x 240 Resolution 1.27 x 1.2 mm Acquisition time 7 seconds ( uses 2 TR to establish steady state) 

 

Thick Axial MRCP

Thin Slice - For detailed depiction of gallstones or ductal obstruction 

  • Fat suppressed single shot HASTE Coronal 

  • TR 11.9 (infinite) Te 95 ETL 128 13 slices 4 m thick FOV 270 mm (7/8) matrix 256 x 240 resolution 1.13 x 1.05 mm Acquisition time 20 seconds

Coronal MIP MRCP
