Project overview
This study compares the diagnostic performance of Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) in evaluating acute stroke among 30 patients in a tertiary care hospital in Kolkata. The research highlights MRI’s superior sensitivity (100%) in detecting acute and lacunar infarcts, compared to CT’s sensitivity of 88.8% and specificity of 79.5%. While CT remains the preferred first-line modality for rapid exclusion of hemorrhage due to its speed and accessibility, MRI offers greater accuracy in detecting early ischemic changes and smaller lesions. The study also explores correlations between imaging findings, clinical variables (age, sex, diabetes, hypertension, smoking, atrial fibrillation), stroke severity (NIHSS scores), and outcomes. Thrombolysis was administered in 70% of cases and was associated with improved clinical outcomes, though all deteriorations and deaths occurred in this subgroup, emphasizing the need for precise imaging-based selection.
