Low‐field MRI: Clinical promise and challenges

open access: yesJournal of Magnetic Resonance Imaging, Volume 57, Issue 1, Page 25-44, January 2023., 2023
Modern MRI scanners have trended toward higher field strengths to maximize signal and resolution while minimizing scan time. However, high‐field devices remain expensive to install and operate, making them scarce outside of high‐income countries and major population centers.

Transcranial Doppler Versus CT-Angiography for Detection of Cerebral Vasospasm in Relation to Delayed Cerebral Ischemia After Aneurysmal Subarachnoid Hemorrhage:A Prospective Single-Center Cohort Study: The Transcranial doppler and CT-angiography for Investigating Cerebral vasospasm in Subarachnoid hemorrhage (TACTICS) study [PDF]

open access: yes, 2019
Cerebral vasospasm in the first 2 weeks after aneurysmal subarachnoid hemorrhage is recognized as a major predictor of delayed cerebral ischemia. The routine screening for cerebral vasospasm with either transcranial Doppler or CT angiography has been ...

Unruptured brain arteriovenous malformations causing seizures localize to one common brain network

open access: yesJournal of Neuroscience Research, Volume 101, Issue 2, Page 245-255, February 2023., 2023
Seizures are a frequent symptom of unruptured brain arteriovenous malformations (bAVMs). Using VLSM and LNM analyses, we indicated that unruptured bAVMs causing seizures, while anatomically heterogeneous, were located within a common network, which could be a plausible neuroimaging biomarker for the prediction of possible seizures.

CAVE: Cerebral Artery-Vein Segmentation in Digital Subtraction Angiography [PDF]

open access: yes, 2022
Cerebral X-ray digital subtraction angiography (DSA) is a widely used imaging technique in patients with neurovascular disease, allowing for vessel and flow visualization with high spatio-temporal resolution. Automatic artery-vein segmentation in DSA plays a fundamental role in vascular analysis with quantitative biomarker extraction, facilitating a ...
