Figure 8. — Case 3. Comparison between 1.5T and 3T. (a) 3T Contrast-enhanced magnetic resonance angiography (MRA) localizer with corresponding 3T (top row) and 1.5T (bottom row) axial MR images of the right internal carotid artery plaque outlined by the dashed yellow line. The vulnerable area has a variable appearance on MR while the calcifications are iso- to hypointense on all sequences. (b) Enlarged axial 3T pre- and post-contrast T1-weighted (T1W) images show a hypointense area with minimal enhancement, consistent with the focal area of lipid necrosis and calcification seen on histopathology.
