Dynamic pseudo‐continuous arterial spin labeling angiography using a 3D‐radial multi‐spoke spoiled gradient‐recalled sequence

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose Accurate identification of arterial feeders and draining veins is critical for treatment decision‐making in patients with intracranial high‐flow vascular lesions. Currently available MRI sequences lack the temporal and spatial resolution needed for this task.

Combined angiography and perfusion using radial imaging and arterial spin labeling with structural contrast

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose To develop a non‐contrast MRI method for the simultaneous acquisition of time‐resolved 3D angiographic, perfusion, and multi‐contrast T1‐weighted structural brain images in a single 6 min acquisition. Methods The proposed combined angiography and perfusion using radial imaging and arterial spin labeling with structural contrast (CAPRIA+

Ex vivo human brain volumetry: Validation of MRI measurements

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose The volume of in vivo human brains is determined with various MRI measurement tools that have not been assessed against a gold standard. The purpose of this study was to validate the MRI brain volumes by scanning ex vivo, in situ specimens, which allows the extraction of the brain after the scan to compare its volume with the gold ...

Acute hemichorea‐hemiballism as the initial sign of cortical cerebral infarction: A case report

Neuroprotection, EarlyView.
Abstract Hemichorea‐hemiballism is classically associated with the contralateral basal ganglia, particularly involving the putamen and subthalamic nucleus, whereas cortical involvement remains a rare etiology. In this case, we present a patient with acute hemichorea‐hemiballism secondary to multiple cortical infarcts demonstrated by neuroimaging.
