Hemorrhage Volume Drives Early Brain Injury and Outcome in Poor-Grade Aneurysmal SAH
BACKGROUND AND PURPOSE: Early brain injury is a major determinant of clinical outcome in poor-grade (World Federation of Neurosurgical Societies IV–V) aneurysmal SAH and is radiologically def...
Shift Volume Directly Impacts Neuroradiology Error Rate at a Large Academic Medical Center: The Case for Volume Limits
BACKGROUND AND PURPOSE: Unlike in Europe and Japan, guidelines or recommendations from specialized radiological societies on workflow management and adaptive intervention to reduce error rates a...
Clinical Evaluation of a 2-Minute Ultrafast Brain MR Protoc...on of Acute Pathology in the Emergency and Inpatient Settings
BACKGROUND AND PURPOSE: The use of MR imaging in emergency settings has been limited by availability, long scan times, and sensitivity to motion. This study assessed the diagnostic performance o...
Understanding Bias in Artificial Intelligence: A Practice Perspective
SUMMARY: In the fall of 2021, several experts in this space delivered a Webinar hosted by the American Society of Neuroradiology (ASNR) Diversity and Inclusion Committee, focused on expanding th...
Intraluminal Flow Diverter Design Primer for Neurointerventionalists
SUMMARY: The clinical use of flow diverters for the treatment of intracranial aneurysms has rapidly grown. Consequently, the market and technology for these devices has also grown. Clinical perf...

Compressed Sensitivity Encoding Artificial Intelligence Acc...is Imaging by Optimizing Image Quality and Reducing Scan Time
BACKGROUND AND PURPOSE: Accelerating the image acquisition speed of MR imaging without compromising the image quality is challenging. This study aimed to evaluate the feasibility of contrast-enh...
The Management of Persistent Distal Occlusions after Mechan...my and Thrombolysis: An Inter- and Intrarater Agreement Study
BACKGROUND AND PURPOSE: The best management of patients with persistent distal occlusion after mechanical thrombectomy with or without IV thrombolysis remains unknown. We sought to evaluate the ...
Arterial Spin-Labeling and DSC Perfusion Metrics Improve Ag...e Glioma Surveillance MR Imaging--An Institutional Experience
BACKGROUND AND PURPOSE: MR perfusion has shown value in the evaluation of posttreatment high-grade gliomas, but few studies have shown its impact on the consistency and confidence of neuroradiol...
A Clinical and Imaging Fused Deep Learning Model Matches Expert Clinician Prediction of 90-Day Stroke Outcomes
BACKGROUND AND PURPOSE: Predicting long-term clinical outcome in acute ischemic stroke is beneficial for prognosis, clinical trial design, resource management, and patient expectations. This stu...
High-Grade Astrocytoma with Piloid Features: A Dual Institutional Review of Imaging Findings of a Novel Entity
SUMMARY: High-grade astrocytoma with piloid features (HGAP) is a recently identified brain tumor characterized by a distinct DNA methylation profile. Predominantly located in the posterior fossa...
Predictors of In-Stent Stenosis Following the Implantation ...at or beyond the Circle of Willis in the Anterior Circulation
BACKGROUND AND PURPOSE: In-stent stenosis is commonly observed after stent implantation. There is no consensus on the contributing factors for in-stent stenosis, especially for aneurysms located...
