From: The carotid plaque imaging in acute stroke (CAPIAS) study: protocol and initial baseline data
Axial images of specific AHA-LT VI plaque features in a patient with acute ischemic infarct. High-resolution black blood MRI of the carotid arteries demonstrate a large eccentric plaque with <50% stenosis in the right carotid artery, hyperintense on T1w, T2w and PDw sequences consistent with fresh intraplaque hemorrhage (A, arrow). Axial images 0.6 cm above the bifurcation show an area attached to the plaque, which is hypo- to isointense on T1w + CM, PDw and TOF, consistent with a mural thrombus (B, arrow). (T1w: T1-weighted black blood sequence, PDw: PD-weighted sequences, T2w: T2-weighted sequence, TOF: Time-of-flight MR angiography, T1w + CM: T1-weighted black blood sequence after contrast administration).
