Hypoxemia [R09.02], Reason for Study: ^Reason: patient with embolic strokes. Further evaluate mechanism of stroke History: above Brain MRIThere are multiple scattered both supra and infra tentorial restricted diffusion lesions indicating acute/subacute ischemic infarctions. There is no evidence of hemorrhagic transformation.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. The midline structures and cranial-cervical junction are normal. The paranasal sinuses are clear.Bilateral mastoid air cells show opacifications.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. Bilateral Pcom arteries and Acom artery are patent. No evidence of intracranial arterial aneurysm. No intracranial arterial luminal stenosis.
1. Multifocal supra and infratentorial acute/subacute ischemic infarctions without evidence of hemorrhagic transformation.2. Normal brain MRA
