Differences in Cervical Spine Fractures in Patients Younger...n 65 Years of Age: Implications for the Canadian C-Spine Rule
BACKGROUND AND PURPOSE: There has been a distinction made in the 2001 Canadian C-Spine Rule regarding patients 65 and older and younger than 65 years of age as far as indications for cervical sp...
Clinical and Pathophysiologic Correlates of Basilar Artery Measurements in Fabry Disease
BACKGROUND AND PURPOSE: Alterations of the basilar artery (BA) anatomy have been suggested as a possible MRA feature of Fabry disease (FD). Nonetheless, no information about their clinical or pa...
NeuroMix with MRA: A Fast MR Protocol to Reduce Head and Neck CTA for Patients with Acute Neurologic Presentations
BACKGROUND AND PURPOSE: Overuse of CT-based cerebrovascular imaging in the emergency department and inpatient settings, notably CTA of the head and neck for minor and nonfocal neurologic present...
Intra-Aneurysmal High-Resolution 4D MR Flow Imaging for Hemodynamic Imaging Markers in Intracranial Aneurysm Instability
BACKGROUND AND PURPOSE: Prediction of aneurysm instability is crucial to guide treatment decisions and to select appropriate patients with unruptured intracranial aneurysms (IAs) for preventive ...
Neuroimaging Correlates with Clinical Severity in Wilson Disease: A Multiparametric Quantitative Brain MRI
BACKGROUND AND PURPOSE: Previous studies have reported metal accumulation and microstructure changes in deep gray nuclei (DGN) in Wilson disease (WD). However, there are limited studies that inv...
Prognosis of Proximal and Distal Vertebrobasilar Artery Stent Placement
