PURPOSE Kinetic analysis using dynamic contrast enhanced MRI to assess neovascularization of carotid plaque requires images with high spatial and temporal resolution. This work demonstrates a new three-dimensional (3D) dynamic contrast enhanced imaging sequence, which directly measures the arterial input function with high temporal resolution yet maintains(More)
Neuroimaging is a critical element in evaluating and treating patients with cerebral aneurysms. Each neuroimaging technique has unique strengths, weaknesses, and current developments. In this review, we discuss the utility of two primary noninvasive radiological techniques—computed tomography angiography (CTA) and magnetic resonance angiography (MRA)—as(More)
We utilise a clinical case to highlight why exclusion of voltage-gated potassium channel (VGKC)-complex autoantibody testing in serological evaluation of patients may delay or miss the diagnosis. A 68-year-old man presented with increasing involuntary movements consistent with faciobrachial dystonic seizures (FBDS). Initial evaluation demonstrated VGKC(More)
OBJECTIVE Aneurysmal subarachnoid hemorrhage management is hampered by our incomplete understanding of what variables promote aneurysm formation, growth, and rupture. Because hypovitaminosis D has been identified as a risk factor for other vascular diseases, we examined its association with cerebral aneurysms requiring treatment. METHODS We(More)
9:01 A 7-­‐Channel Sodium and a 4-­‐Channel Proton Breast Array for Imaging at 3T (8 min). 9:09 Imaging acute endotoxin-­‐induced lung injury in a rat model (8 min). 9:17 18F-­‐FDG and FLT PET for early prediction of response to targeted chemotherapy in advanced lung cancer. 9:37 18 F-­‐FDG PET-­‐CT in the evaluation of patients with persistent febrile(More)
in the article “High-Resolution Vessel Wall MRI: Appearance of Intravascular Lymphoma Mimics Central Nervous System Vasculitis,” [1] Schaafsma et al. describe two interesting cases of biopsy-proven intravascular lymphoma (IVL) that mimicked the vessel wall MRI (vwMRI) appearance of vasculitis, with concentric arterial wall thickening and enhancement. To our(More)
This case report illustrates the neuroanatomy and neurovascular anatomy of the cervical spinal cord by exploring the pathophysiology of cervical cord infarction secondary to vertebral artery injury. The spinal cord is made up of several important tracts, including the dorsal column medial lemniscus system, corticospinal tracts, and the anterolateral system.(More)
Background Carotid intraplaque hemorrhage (IPH) seen on vessel wall MRI is associated with an increased risk of stroke or transient ischemic attack, as are microembolic signals (MES) detected by transcranial Doppler (TCD). We sought to examine the association between IPH and MES in acute stroke patients with symptomatic carotid atherosclerosis. Methods(More)
