Educational Modules

1 - Clinical Presentation of Acute Stroke

This module will introduce you to the initial presentation of acute stroke and clinical features to help recognize signs and symptoms of stroke. Localization of symptoms and clues provided in the clinical exam will be discussed. Associated clinical syndromes of stroke will be discussed.

2 - Potential Etiological Causes of Acute Ischemic Stroke

Pathophysiology of vascular occlusion could depend on a number of underlying patient factors and conditions. Many etiological causes exists that either causes in vessel thrombosis, for example coagulopathy, while others may include an embolic source such as in atrial fibrillation or intrinsic to cardiac defects. Potential etiological causes of stroke will be explored in this module in an example based format.

3 - Radiologic Imaging Modalities in Diagnosis of Acute Stroke

Overview of basic imaging armementerium and strategoies for detection of vascular occlusion and tissue involved in acute ischemic stroke. Different imaging modalities, such as CT, CTA, mCTA, CTP, and MRI, along with their advantages and drawbacks will be discussed.

4 - Non-Contrast CT Head Findings

Findings on non-contrast CT head and early parenchymal changes associated with acute vascular occlusion will be discussed highlighting important imaging signs to look for and note ignore. Multiple case based examples will take you through how to better identify these signs to detect early ischemic stroke.

5 - Calculating the ASPECT Score

Alberta Stroke Program Early CT score (ASPECTS), a 10-point quantitative score used to assess early ischemic changes on non-contrast CT head will be discussed.

ASPECTS score is a simple and reliable tool for detection of early ischemic changes on initial non-contrast CT scans of the brain.

6 - ASPECTS Case Scenarios

Case examples of the determination and use of the ASPECTscore in clinical decision making will be discussed. Asignment of scoring and the pearls and pitfalls of determining the score will be focused on.

7 - Vascular Imaging & CTA in Stroke

Identification of the primary site of vascular occlusion/s will be discussed in this module focusing on the importance of cloth identification, characterization, and patterns indicative of potential  source of embolic or thrombotic events.

8 - What is Multiphase CTA (mCTA) and Collateral Score?

The concepts behind multiphase CTA and assistive roles of contrast hold up or delay on the additional phases in identification of the site of vascular occlusion will be discussed. Assessment of collateral circulation and scoring of collateral vessels will be introduced.

9 - mCTA Case Scenarios

Case based examples of the use of collateral score on mCTA and categorization of collaterals will be discussed.

10 - Treatment Approaches in Ischemic Stroke

Both Clinical and Endovascular approaches to treatment of acute stroke will be discussed in the context of cloth location, size, onset of presentation, imaging changes, collateral circulation, and more.

11 - Endovascular Treatment (EVT) of Acute Stroke

General approach to the procedure and selective identification of patients that would benefit from mechanical thrombectomy will be discussed. Recent advances in technique and equipment used in EVT will be talked about highlighting the importance of their role in the clinical trials investigating the efficacy of the intervention.

12 - Technical Imaging Notes

Tips and tricks on how to improve imaging of acute stroke and detection of early ischemic changes. Role of MIP reconstruction, multiplanar reformats, contrast timing, and other technical aspects of performing and reconstructing the images will be dicussed.
