TL;DR: This study shows the earliest known biomarker changes in cognitively normal people at genetic risk for autosomal dominant Alzheimer's disease with functional and structural MRI findings and CSF and plasma biomarker findings consistent with Aβ(1-42) overproduction.
Journal Article
Diffusion-weighted MR imaging of global cerebral anoxia.
TL;DR: High-strength diffusion-weighted images showed the abnormal basal ganglia, cerebellum, and cortex to a better extent than did conventional MR images during the acute period and therefore aid in the determination of prognosis and management of patients with diffuse cerebral anoxia.
Journal ArticleDOI

TL;DR: Functional studies revealed that LPHN3 variants are expressed in key brain regions related to attention and activity, affect metabolism in neural circuits implicated in ADHD, and are associated with response to stimulant medication.
Journal Article
Diffusion-weighted MR imaging offers no advantage over routine noncontrast MR imaging in the detection of vertebral metastases
TL;DR: Diffusion-weighted MR imaging of the spine showed no advantage in the detection and characterization of vertebral metastases as compared with noncontrast T1- Weighted imaging, but was considered superior to T2- weighted imaging.
Journal Article
Acute Marchiafava-Bignami Disease: MR Findings in Two Patients
TL;DR: The MR imaging findings in two patients who presented acutely with Marchiafava-Bignami are presented and the features of the disease and of other acute alcohol-related disorders are reviewed.
