Prevalence of Stroke and Diagnostic Performance of Emergency MRI in Acute Isolated Dizziness.

ABSTRACT:

Objective

Stroke is frequently misdiagnosed in patients presenting with acute isolated dizziness; the optimal imaging modality for this population remains debated. This study aimed to determine the prevalence of stroke among patients with isolated dizziness and to assess the diagnostic accuracy of magnetic resonance imaging (MRI) and computed tomography (CT) for stroke detection.

Methods

Consecutive patients presenting to the neuroemergency department with acute dizziness between April and December 2024 were enrolled. Isolated dizziness, defined as dizziness or vertigo without accompanying neurological deficits, was identified. Clinical characteristics were compared between patients with and without stroke. The diagnostic performance of MRI and CT for detecting stroke in pat
