Cost-effectiveness of CT perfusion, low-field MRI, and delayed high-field MRI in emergency department patients with dizziness concerning for stroke

Evaluation of follow-up brain magnetic resonance imaging in patients with ischemic stroke

This study aimed to assess the diagnostic yield of follow‑up diffusion‑weighted magnetic resonance imaging (DWI‑MRI) in emergency department patients with suspected acute ischemic stroke who had an initial negative scan, and to identify associated risk factors. In this retrospective cross‑sectional analysis, we reviewe...

Challenges and Adjunctive Use of CT Perfusion (CTP) in Acute Stroke: Pitfalls, False Negatives, and Diagnostic Clues for Stroke Mimics

Diagnostic challenges in posterior circulation ischemic stroke presenting with acute dizziness and vertigo

Posterior circulation stroke (PCS) is a common and clinically important cause of acute dizziness and vertigo, accounting for approximately 20–25% of all acute ischemic strokes. Because PCS frequently presents with non-specific, fluctuating, or isolated vestibular symptoms, it is about three times more likely to be init...

Clinical and Anatomical Characteristics of Ischaemic Stroke Patients Undergoing Non-Contrast CT in a Nigerian Multicentre Cohort: Evidence of a Prolonged Stroke Onset-to-CT Scan Interval.

Background: Ischaemic stroke is a major cause of death and long-term neurological disability, and clinical outcomes are strongly affected by the interval between symptom onset and definitive assessment. Non-contrast computed tomography (NCCT) remains the principal initial neuroimaging examination for suspected acute st...

Timely access to computed tomography and magnetic resonance imaging in acute critical conditions: clinical and health system outcomes. A scoping review

Red Cell Distribution Width (RDW) Level as one of the Alternative Diagnostic Tools in Stroke Patients

Background: Stroke is an emergency that requires prompt treatment. Non-contrast head computed tomography (CT) is the preferred imaging modality for diagnosing stroke due to its accessibility and speed, but it’s not always available. There are many alternative diagnostic scales for stroke, such as the Siriraj and Gadjah...
