Ischemic Stroke: A Comprehensive Guide for Neuroimaging Clinics

This issue of Neuroimaging Clinics of North America, edited by Dr. Lotfi Hacein-Bey, focuses on the critical topic of Ischemic Stroke. It covers a wide range of articles that provide insights into the clinical distinction of cerebral ischemia, triaging of patients in the ED, and various imaging techniques including CT, CTA, CT perfusion, MRI, and advanced neuroimaging methods.

Clinical Distinction of Cerebral Ischemia and Triage

The first article discusses the clinical distinction of cerebral ischemia and triaging of patients in the emergency department. It highlights the importance of identifying mimics, wake-ups, late strokes, and chameleons to ensure accurate diagnosis and timely treatment.

Telestroke and Remote Patient Management

Telestroke is a rapidly evolving field that enables remote management of stroke patients. This article explores the benefits and challenges of implementing telestroke services, including improved patient outcomes and reduced healthcare costs.

Imaging Techniques for Acute Stroke

Several articles are dedicated to various imaging techniques for acute stroke, including CT, CTA, CT perfusion, and MRI. These imaging modalities play a crucial role in diagnosing stroke, assessing the extent of damage, and guiding treatment decisions.

Advanced Neuroimaging of Acute Stroke

Advanced neuroimaging techniques, such as collateral imaging, permeability imaging, and Arterial Spin Labeling, offer deeper insights into the pathophysiology of stroke. These methods can help identify potential therapeutic targets and monitor treatment response.

Understanding Hypoperfusion and Infarction

This section delves into the understanding of hypoperfusion, oligemia, and infarction using neuroimaging. It discusses the implications of these concepts for stroke management and patient outcomes.

Pathophysiology of Thrombus and Clinical Implications

The pathophysiology of thrombus formation and dissolution is a complex process that significantly influences stroke outcomes. This article examines the clinical implications of thrombus dynamics and potential therapeutic strategies.

Neuro-Interventional Management of Stroke

Neuro-interventional procedures, such as thrombectomy and angioplasty, have revolutionized the management of acute stroke. This article reviews the current state of neuro-interventional techniques and their role in improving patient outcomes.

Non-Interventional Treatment Options for Stroke

While interventional procedures have gained prominence, non-interventional treatment options remain essential for many stroke patients. This article discusses the various non-interventional approaches, including pharmacological therapies and rehabilitation strategies.

Post-Stroke Neuroimaging and Reperfusion Changes

Post-stroke neuroimaging is critical for assessing treatment response, identifying complications, and guiding further management. This section also explores reperfusion changes after stroke and practical approaches for neuroprotection.

Economics of Stroke Treatment and Health Care Organization

The final articles in this issue focus on the economics of stroke treatment, including value-based payment models, and the organization of neuroradiological management of stroke at regional and national levels, using the French experience as a case study.
