Left carotid plaque irregularity with bilateral frontal and left parietal acute ischemic infarction indicating possible symptomatic plaque. Initially TOF survey scan was performed, the target area of the left CCA bifurcation was selected.There is eccentric carotid plaque on the left carotid bifurcation and proximal extracranial left ICA.The plaque is best seen on series #801, image 23/30.The plaque shows relatively homogenous high signal intensity on T1 black blood images and low signal intensity on T2 weighted images indicating lipid fibrous core.On series 801, image 15 to 22/30 and series 1401 image 4 to 17/17 show focal crescentic shaped low signal intensity lesion on the surface of the plaque may suggest ulceration of plaque inhomogeneity of plaque (mixed intermediate signal intensity with high signal intensity of plaque) may indicate possible complex plaque, in other words, intra plaque hemorrhage (high signal intensity portion can suggest possible intra plaque hemorrhage).The right carotid bulb also demonstrated carotid plaque with high signal intensity on T1 and T2 weighted images indicating lipid core.Otherwise no remarkable finding.
1. Demonstration of bilateral CCA bifurcation atheromatous plaques, left side is more prominent and irregular than right.2. Mixed signal intensities of the left carotid bulb plaque may indicate complex plaque (intra plaque hemorrhage).3. Bilateral carotid bifurcation plaques (lipid core) were seen.
