MULTIPARAMETRIC MAGNETIC RESONANCE IMAGING IN THE EVALUATION OF ACUTE ISCHEMIC STROKE: DIAGNOSTIC AND PROGNOSTIC IMPLICATIONS

Abstract

Acute ischemic stroke is one of the leading causes of morbidity and mortality worldwide, requiring rapid and accurate diagnosis to guide effective therapeutic interventions. In this context, imaging methods play a central role in identifying ischemic injury and determining eligibility for reperfusion therapies. This study consisted of an integrative literature review conducted between 2021 and 2026, aiming to analyze scientific evidence regarding the use of multiparametric magnetic resonance imaging in the evaluation of acute ischemic stroke. The search was performed in national and international databases using predefined descriptors and applying established inclusion and exclusion criteria. The findings demonstrated that the integration of structural, functional, and quantitative sequences increases diagnostic accuracy, improves estimation of the therapeutic time window, and enhances prediction of clinical outcomes. Although computed tomography remains the first-line imaging modality in emergency settings, multiparametric magnetic resonance imaging stands out as a strategic complementary tool with significant prognostic value.
