Abstract:
Objective To evaluate Feridex(superparamagnetic iron oxide,SPIO)enhanced MRI in the diagnosis of hepatic lesions.Methods Feridex-enhanced MRI was performed in 31 patients with CT,or MRI proved or suspected hepatic lesions.T 2WI signal intensity of hepatic parenchyma,lesion and background noise was measured before and after enhancement separately.SNR and CNR of parenchyma and lesion before and after enhancement were calculated.The number of lesions on plain and enhanced scans were observed and alalyzed.Results Post-enhancement SNR of liver significantly decreased (?0.05).Post-enhancement lesion-liver CNR increased significantly (?
