Diagnostic Value of Semiquantitative Analysis of Dynamic Susceptibility Contrast Magnetic Resonance Imaging with GD-EOB-DTPA in Focal Liver Lesions Characterization: A Feasibility Study

Figure 3

An 81-year-old man with liver cirrhosis-HCV related and with histologically proven HCC in the second segment. DCE-MR was performed to establish the presence of focal liver lesion. (a) Axial T1-weighted in-phase echo-gradient sequence shows a hyperintense nodular area in the second segment, due to presence of glycogen deposition. (b, c) Axial arterial and delayed postcontrast phase MR images show in arterial phase the presence of increased enhancement of nodular lesion, followed by washout in delayed phase. (d) Axial T2 fat-sat weighted sequence shows a weakly hyperintense nodular area in the second segment. (e, f) On colour perfusion maps (Relative Arterial Enhancement and Relative Late Enhancement, resp.) the ROIs (ROI contouring the boundaries of the lesion) were positioned on nodular lesion, and the corresponding perfusion maps show a hypervascular area, characterized by a different colour compared to the surrounding liver parenchyma with hypointensity signal in perfusion maps created for the delayed phase (f).
