To detect and characterize focal liver lesions
- Scout (multiple planes)
- T2 weighted Axial with fat suppression
- T1 out of phase Spoiled Gradient Echo (SGE) Axial
- If the lesion is bright on T1 do a fat saturated T1 Axial
- T1 in phase SGE Axial
Post Contrast (0.2ml/kg rapid injection followed by 10 ml saline flush)
- T1 In Phase FLASH Axial at :-
- End of saline flush,
- 45 seconds post contrast
- 3 minutes post contrast
- 10 minutes post contrast (optional)
- MRCP axial, RAO for Hepatic ducts, LAO for pancreatic duct
Notes
- The pre-contrast images locate lesions and provide T1 and T2 weighted information.
- Out of Phase (OOP) FLASH images display fatty infiltration and adrenal adenomas.
- The post contrast images help classify the nature of the lesion.
- The immediate post contrast image is very time critical, and is the most valuable.
- The rapid injection requires good venous access. Have the 20 G Jelco in situ before the patient is placed in the bore ( before they enter the room if possible).
