Three-dimensional (3D) magnetic resonance (MR) projection imaging was evaluated as a noninvasive alternative to direct cholangiography in 12 patients with malignancy-related obstructive jaundice. The 3D images of the bile ducts were formed by subjecting consecutive coronal MR images obtained with a fast imaging method to a maximum-intensity projection algorithm. Dilatation and obstruction of the biliary system were well documented in all cases, and good correlation between findings at 3D MR…

Three-dimensional computed tomography cholangiography: a new technique for biliary tract imaging.
TLDR
3D cholangiography provided a useful adjunct to other imaging techniques in patients with complex hilar strictures it aided implementation of appropriate interventional drainage procedures.
Magnetic resonance cholangiography
TLDR
Three patients with obstructive jaundice who underwent magnetic resonance imaging of the liver were studied, and magnetic resonance cholangiography images compare favorably with those acquired on scanners in which special breath-holding gradient echo protocols are used.
Computed tomographic cholangiography using spiral scanning and 3D image processing.
TLDR
Volumetric computed tomography scans ("spiral CT") were performed after intravenous (i.v.) cholangiography followed by additional 3D surface reconstructions of gallbladder and biliary ducts and sufficient contrast was found in the common bile duct.
MR cholangiography in biliary obstruction using half-Fourier acquisition.
TLDR
HASTE MRC can safely and accurately depict the presence and level of biliary obstruction and should be considered an alternative procedure to direct cholangiography in selected patients.
MR cholangiography in the examination of patients with biliary-enteric anastomoses.
TLDR
MR cholangiography is a reliable imaging technique for the examination of patients with biliary-enteric anastomoses and correctly showed bile duct irregularities in six of the eight patients with cholangsitis and anastOMotic strictures in all 19 patients with strictures.

MR cholangiopancreatography: efficacy of three-dimensional turbo spin-echo technique.
TLDR
Respiratory-triggered, multislab, three-dimensional turbo spin-echo MR cholangiopancreatography is a noninvasive technique for visualization of the pancreatic and biliary ductal systems and should be the technique of choice when invasive techniques are incomplete, unsuccessful, or technically difficult.
Breath-hold MR cholangiopancreatography with three-dimensional, segmented, echo-planar imaging and volume rendering.
TLDR
End-expiration, 21-second breath-hold, three-dimensional magnetic resonance (MR) cholangiopancreatography (MRCP) was developed with segmented echo-planar imaging and clear depiction of biliary, hepatic, and pancreatic ducts was possible with good signal-to-noise ratio.
MR cholangiography of late biliary complications after liver transplantation.
TLDR
MR cholangiography can show biliary obstruction and provide important information for planning therapeutic procedures and excellent correlation with contrast-enhanced cholangsiographic findings are found.
MR cholangiopancreatography at 0.5 T with a 3D inversion recovery turbo-spin-echo sequence
TLDR
The MRCP technique at 0.5 T is an accurate method for the assessment of pathology of the biliary tree and all calculi were accurately predicted by MRCp.
