Occlusion and stenosis of right vertebral artery [I65.01] / Dizziness and giddiness [R42] / Muscle weakness (generalized) [M62.81], Reason for Study: ^Reason: evaluate for stroke History: vertigo, L sided leg > arm weakness, gait instability, slurred speech Brain MRIMotion artifact degraded image quality.No evidence of acute ischemic or hemorrhagic lesion on the scan.Multiple scattered T2/flair high signal intensities on bilateral periventricular white matter indicate nonspecific small vessel ischemic disease. The ventricles, sulci and cisterns are symmetric and unremarkable. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, restricted diffusion/acute ischemia, or abnormal contrast enhancement. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear. Bilateral lens signal is not seen indicating postoperative status with bilateral staphylomatous changes, unchanged since prior scan.Brain MRA3D time of flight MOTSA MRA brain images with maximum intensity projections of the anterior/posterior intracranial circulation demonstrate normal ICAs, MCAs and ACAs. Vertebrobasilar system appears to be normal. There is no evidence of significant arterial luminal stenosis. No intracranial arterial aneurysm is seen.
1. No evidence of acute ischemic or hemorrhagic lesion on the scan.2. Minimal nonspecific small vessel ischemic disease.3. Normal brain MRA
