Figure 5. — Case 2. Comparison between 1.5T and 3T. (a) 3T time of flight-magnetic resonance angiography (TOF-MRA) localizer with corresponding 3T (top row) and 1.5T (bottom row) axial MR images of the right carotid artery plaque (dashed yellow line), located at the carotid bifurcation. (b) Enlarged pre- and post-contrast 3T T1-weighted (T1W) images demonstrate a hypointense lipid-rich necrotic core (green arrow) and adjacent intraplaque hemorrhage (red arrow), which appears iso- to hyperintense on the post-contrast image. The fibrous cap (chevron) is noted as a high-intensity band on the post-contrast T1W image.
