Role of Susceptibility Weighted Imaging in Acute Ischemic Stroke: A Cross-Sectional Study
Abstract: Introduction: Acute ischemic stroke (AIS) is a major cause of morbidity and mortality worldwide. Imaging plays a pivotal role in early detection and clinical decision-making. Objective: To assess the diagnostic and prognostic value of Susceptibility Weighted Imaging (SWI) in acute ischemic stroke. Material and Methods: A cross-sectional study was conducted on 86 patients with suspected AIS. MRI including SWI was performed within 7 days of symptom onset. SWI findings were correlated with NIHSS scores, treatment status, and discharge outcomes. Results: SWI abnormalities were present in 39.5% of patients. Microbleeds were the most common finding (16.3%), followed by hemorrhagic transformation (11.6%) and susceptibility vessel signs (9.3%). Hemorrhagic transformation was significantly associated with thrombolytic therapy (p = 0.021). Conclusion: SWI offers valuable diagnostic and prognostic information in AIS. Its routine integration into stroke imaging protocols is recommended.
