  • Characterization Value of Focal Hepatic Lesions with Feridexs-Enhanced MR Imaging

    【Abstract】Objective To compare radiologists’ performance on combined unenhanced and feridexs-enhanced MR imaging (MRI) with their performance on helical CT enhanced, unenhanced MRI, and feridexs-enhanced MR alone imaging for the characteristics of local hepatic lesions. Methods MR images and CT scans obtained in 26 patients with 57 local hepatic lesions were analyzed with reviewer operator characteristic (ROC) curve analysis. The imaging of patient were divided into 4 groups including combined unenhanced and feridexs-enhanced MRI group, helical CT enhanced group, unenhanced MRI group, and feridexsenhanced MR alone group. Results The combined approach resulted in larger area under the ROC curve (Az=0.926 0) and accuracy (86.8%),P<0.05,as compared with the others methods. There were no significant differences among the other three methods. Conclusion Feridexs-enhanced MRI was more accurate than enhanced helical CT scan in characterization of local hepatic lesion. The combined analysis of unenhanced and feridexs-enhanced images was more accurate in the characterization of focal hepatic lesions than was review of feridexs-enhanced images alone.
