Unspecified dementia without behavioral disturbance [F03.90], Reason for Study: ^Reason: Patient with progressive cognitive decline - assess for signs of CJD and/or cerebrovascular disease. History: progressive decline in memory and behavior. Significant motion artifact degraded image quality.There are subtle diffusion image high signal intensities on bilateral superior parietal lobules and right side inferior parietal lobule. Corresponding FLAIR images show subtle high signal intensities but T2 weighted images do not demonstrate those lesions. Thus, above described lesions could be artifactual or subacute ischemic lesions.Gradient echo images do not show definitive focus of susceptibility lesion, however, again due to significant motion artifact, thorough evaluation is not possible.There are patchy FLAIR high signal intensity lesions on bilateral periventricular white matter and centrum semiovale indicating possible small vessel ischemic disease.The ventricles, sulci and cisterns are unremarkable. There is no mass, mass effect, edema, or midline shift. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses are clear.Left mastoid air cells show opacifications.
1. Significant motion artifacts degraded image quality.2. Subtle FLAIR high signal intensity lesions on bilateral parietal lobes are seen which could be artifacts or subacute ischemic lesions.3. No evidence of mass, mass effects or definitive hemorrhagic focus on this scan.Comment: the imaging request includes DTI scan as well as post contrast MR scans. However, considering significant motion artifacts, it was decided not to proceed for the DTI and post contrast scan today. Instead, it might need to be rescheduled for more detailed examination. This was discussed with Dr.Dellaria who is a resident of Dr Mastrianni at the time of this dictation.
