"non-contrast: often homogeneous hypoattenuating relative to liver parenchyma; density will be similar to blood pool"
"late arterial phase: typically shows discontinuous, nodular, peripheral enhancement (small lesions may show uniform enhancement)"
"portal venous phase: progressive peripheral enhancement with more centripetal fill-in"
"delayed phase: further irregular fill-in and therefore iso- or hyper-attenuating to liver parenchyma"
"T1: hypointense relative to liver parenchyma"
"T2: hyperintense relative to liver parenchyma, but less than the intensity of CSF or of a hepatic cyst"
"delayed phase: further irregular fill-in and therefore iso- or hyper-attenuating to liver parenchyma"
"Tc-99m RBC scintigraphy is very sensitive for lesions >2 cm and typically demonstrates decreased activity on initial dynamic images, followed by increased activity on blood pool images 24."
