Female, 62 years old, with acute ischemic stroke. Evaluate vascular patency. Also with right-sided pain and weakness. MRA brain:Image quality is limited by motion artifact. There may be mild vascular narrowing through the cavernous ICAs. No obvious high-grade vascular stenosis or occlusion is detected intracranially. No large aneurysms are seen. The ACOM artery is moderately sized and unremarkable. The PCOM arteries are moderately sized and unremarkable.MRA neck:Image quality is limited by motion artifact. The origins of the great vessels are not well seen though no significant stenosis is suspected. No significant stenosis is suspected at the carotid bifurcations by NASCET criteria. The cervical ICAs appear to be patent though they are not well assessed due to artifact. The vertebral arteries appear to be largely patent though there are portions of each which are not well visualized, possibly due to artifact.Cervical spine:Image quality is limited by motion artifact. Spinal alignment is anatomic. Vertebral body height and morphology are within normal limits. No evidence of marrow edema or concerning marrow replacement is seen.The visualized spinal cord is normal in signal and morphology. No epidural abnormality is suspected.Please note that there is a misregistration between the actual level of the axial slices and the level represented by the scout line on sagittal images. Specifically, the axial images are registering one disc level higher on the sagittal images than they are in reality. C2-3: No spinal canal stenosis or neuroforaminal narrowing. C3-4: Mild posterior disc-osteophyte complex formation. No spinal canal stenosis. No foraminal narrowing. C4-5: Mild posterior disc-osteophyte complex formation, asymmetric to the right. No spinal canal stenosis. No foraminal narrowing. C5-6: Moderate posterior disc-osteophyte complex formation resulting in mild spinal canal stenosis. No significant foraminal narrowing. C6-7: Minimal posterior disc-osteophyte complex formation. No spinal canal stenosis. No foraminal narrowing. C7-T1: No spinal canal stenosis or neuroforaminal narrowing.
1.MRA imaging of the intracranial vessels and the neck is compromised by motion artifact. Within this limitation, no definite causative stenosis or occlusion is seen to account for the patient's ischemic lesions.2.Overall mild degenerative disc disease is seen. C5-6 is the most significantly affected level where there is a mild spinal canal stenosis. 3.Please note that there is a misregistration between the actual level of the axial slices and the level represented by the scout line on sagittal images. Care should therefore be taken when cross-referencing the axial images to the sagittal images.
