 The study is definitely degraded by motion artifacts. MRI BRAIN:There are no restricted diffusion abnormalities. There is no evidence of mass effect, or edema. Ventricular size is normal. There is no midline shift. There is a normal gray-white matter differentiation. Bleed cannot be assessed for due to motion artifacts in the susceptibility images which are nondiagnostic.FLAIR hyperintensity is seen in the periventricular white matter, which is a nonspecific finding and may be related to chronic small vessel ischemic changes.There is status post left-sided craniotomy.MRI CERVICAL SPINE:Axial images were not obtained. On the sagittal views of the cervical spine were obtained which are degraded by motion artifacts and are nondiagnostic. Narrowing of the spinal canal is suggested at the level of C4-C5 and C5-C6, that is not well delineated in this study.MRA BRAIN:The visualized internal carotid arteries, anterior, middle, and posterior cerebral arteries, the basilar and vertebral arteries are grossly patent. No significant stenosis or large aneurysm. The bilateral P-comms are not well visualized.
1. No evidence of acute infarct. Mild nonspecific FLAIR hyperintensity in the periventricular white matter, which could relate to minimal chronic small vessel ischemic changes.2. MRA demonstrates no evidence of large aneurysm or flow-limiting stenosis. 3. Nondiagnostic MRI of the cervical spine; however there is suggestion of possible spinal stenosis at the level of C4-C5 and C5-C6, that is not well delineated in this study. Repeat cervical spine MRI is recommended when able to tolerate.
