Bilateral ACA and left MCA territorial ischemic infarctions. CTA evidence of left carotid bulb plaque irregularity. The 3D T1 weighted WATS sequence was applied.However, the images are blurred especially on posterior lateral aspect of the left carotid bulb prevents detailed analysis.Subtle linear low signal intensity (arrows on series 801, image 29/50) delineating carotid luminal high signal intensity might represent fibrous cap of carotid plaque and irregularity with interruption of the linear low signal intensity could represent ruptured portion of carotid plaque.However, there is no evidence of definitive evidence of fibrous cap interruption or intra-plaque hemorrhage (usually showing high signal intensity on T1 weighted image) on this scan.Black blood imaging attempt was not successful to show carotid bulb wall.Therefore, this MR exam is non-diagnostic.
Non diagnostic MR imaging.
