Study Notes
Dynamic Range of the Image
- Improves signal-to-noise and contrast-to-noise ratios of focal liver lesions
- Very heavily T2-weighted sequences can be used to show water content in bile ducts and cysts, and some focal lesions
Contrast-Enhanced Magnetic Resonance Liver Imaging
- Gadolinium-enhanced T1-weighted magnetic resonance imaging helps in tissue characterization, but does not increase sensitivity for focal abnormalities
Superparamagnetic Iron Oxide (SPIO)
- Also known as RE (Reticulo-Endothelial) agents
- Taken up by the RE or Kuppfer cells in normal liver, giving a decrease in signal on T2- and especially T2*-weighted sequences
- Not currently available due to commercial reasons
MRCP (Magnetic Resonance Cholangiopancreatography)
- A non-invasive technique used to visualize the biliary tree inside and outside the liver and pancreatic duct
- Commonly used to demonstrate the presence of stones and the level and cause of obstruction, especially combined with cross-sectional MRI, in cases of tumor or suspected tumor
Indications for MRI
- Staging of pancreatic tumors
- Suspected islet cell tumor
