The aim of this study was to explore the correlation between thrombus length, thrombus susceptibility, CBS, DWI-ASPECTS, and admission and discharge NIHSS scores between patients with single-segment and multiple-segment thrombi using susceptibility mapping (SWIM). SWIM, reconstructed from magnitude and phase images acquired by an SWI sequence, was used to measure thrombus susceptibility in patients with acute infarction. A higher susceptibility of thrombus was correlated with lower DWI-ASPECTS and increased NIHSS scores. The patients with multiple-segment thrombi had a larger area of cerebral infarction, more severe symptoms, and worse clinical outcomes.
