Overview
Magnetic resonance imaging (MRI) has become the standard method for morphological examination of the bile ducts, particularly for diagnosing cholangitis. T1-weighted and T2-weight sequences offer different results.
MRI
- Once magnetic resonance cholangiopancreatography (MRCP) has been conducted, an MRI scan can be implemented.
- The MRI machine uses radio waves and magnets to scan the internal organs and tissues.[1]
T1-weighted sequences
- T1-weighted sequences are essential in biliary disease when looking for intrahepatic calculi.
- These sequences are recommended during 3D acquisition with fat saturation.[2]
- Fat saturation offers improvements in diagnostic possibilities, especially for the bile ducts close to the hilum of the liver, which is often rich in fat.
T2-weighted sequences
- For examination of the bile duct, T2-weighted sequences with a long echo time are generally used, without fat saturation.[2]
Limitations to MRIs
- Whether T1-weighted, T2-weighted or magnetic resonance cholangiography sequences are involved, the main limitation of bile duct MRI is in its suboptimal spatial resolution.[2]
- Precise examination of the distal bile ducts is still incomplete.
- The three main limitations resulting from MRIs include those that are:[2]
- Technical
- Anatomical
- Semiological
