A Study on Usefulness of Specific Agents with Liver Disease at MRI Imaging: Comparison with Ferucarbotran and Gd-EOB-DTPA Contrast Agents / 의학물리

ABSTRACT

The purpose of this experiment is to know the relation of the detection and characterization of liver's diseases as comparison of finding at MR imaging using a Ferucarbotran (SPIO) and Gd-EOB-DTPA (Primovist) agents in diffuse liver disease. A total of 50 patients (25 men and 25 women, mean age 50 years) with liver diseases were investigated at 3.0T machine (GE, General Electric Medical System, Excite HD) "with 8 Ch body coil for comparison of diseases and contrast's uptake relation, which used the LAVA, MGRE." All images were performed on the same location with before and after Ferucarbotran and Gd-EOB-DTPA administrations (p<0.05). Contrast to noise ratio of Ferucarbotran and Gd-EOB-DTPA in the HCC were 3.08+/-0.12 and 7.00+/-0.27 with MGRE and LAVA pulse sequence, 3.62+/-0.13 and 2.60+/-0.23 in the hyper-plastic nodule, 1.70+/-0.09 and 2.60+/-0.23 in the meta, 2.12+/-0.28 and 5.86+/-0.28 in the FNH, 4.45+/-0.28 and 1.73+/-0.02 in the abscess and ANOVA test was used to evaluate the diagnostic performance of each disease (p<0.05). In conclusions, two techniques were well demonstrated with the relation of the detection and characterization of liver's diseases.
