1 Fig. 3. Representative false-positive cases. A
Fig. 3. Representative false-positive cases. A. Axial image of MIP 3D-GRE shows nodular enhancing lesion (arrow) in right cerebellum of 62-year-old man. In non-MIP 3D-GRE, enhancing vessel was confirmed (not shown). B. Axial image of MIP iMSDE-TSE shows tiny nodular enhancement (arrow) in right temporo-occipital lobe of 64-year-old woman. It was unsuppressed vascular signal. C. Axial image of MIP 3D-GRE shows focal dural enhancement in form of nodular enhancing lesion (arrow) in right frontal lobe of 60-year-old man. D. Axial image of MIP 3D-GRE probably shows two nodular enhancing lesions (arrows) in left occipital lobe of 26-year-old man. They were confirmed as artifacts in non-MIP 3D-GRE. E. In axial image of MIP iMSDE-TSE, artifactual enhancement is presented as nodular enhancing lesion (arrow) of 75-year-old female. MIP iMSDE-TSE = maximum intensity projection of improved motion-sensitized driven-equilibrium prepared contrast-enhanced 3D T1-weighted turbo-spin echo imaging, MIP 3D-GRE = maximum intensity projection of contrast-enhanced 3D T1-weighted gradient-echo imaging, non-MIP 3D-GRE = 1-mm images of contrast-enhanced 3D T1-weighted gradient-echo imaging Fig. 3.
