Focal lesion in liver is best detected by

MRI in Liver lesions MRI had emerged as the best imaging test for liver lesion detection and characterization MRI provides high lesion-to-liver contrast and does not use radiation Liver-specific contrast media, such as mangofodipir trisodium (taken up by hepatocytes) and ferrumoxides (taken up by kupffer cells) demonstrate selective uptake in the liver and primarily used for lesion detection These two contrast agents are also useful in characterising specific liver tumors, such as FNH, hepatic adenoma and HCC Ref: Shackelford 7th edition Pgno : 1560
