Abstract: ObjectiveTo quantitatively assess the texture of carotid soft plaques in patients with or without cerebral infarction using acoustic radiation force imaging(ARFI).MethodsA total of 71 patients with carotid soft plaques were divided into two groups:group A including 31 patients with cerebral infarction and group B including 40 patients without cerebral infarction.ARFI was used to measure the shear wave velocities(SWV) of each soft plaque of the two groups.The results of two groups were compared.Receiver operating characteristic(ROC) curve was drawn to assess the diagnostic accuracy.ResultsThe value of SWV between two groups were significantly different ( P =0.027).The sensitivity and specificity of SWV (AUC =0.667,cut-off value =1.262 m/s) in predicting cerebral infarction was 67.7％ and 70.0％ respectively.ConclusionsThe texture of carotid soft plaques can be evaluated quantitatively using ARFI which was strongly related with cerebral infarction.
