| Popis: | The iPlaque software package can use integrated backscatter (IB) values of carotid plaque to extract information on tissue composition. The aim of this study was to evaluate the association between the plaque histologic classification and IB values evaluated by iPlaque. In 49 patients undergoing carotid endarterectomy, IB values of whole carotid plaque were measured using iPlaque from the long-axis ultrasonographic image. Histologic findings of resected plaques were defined using the classification of the American Heart Association. The average IB values were statistically compared with the classification. Plaque samples from 49 patients were categorized into V, VI and VII, (13, 32 and 4 cases, respectively). Both the average and standard deviation of the IB values in each plaque sample significantly differed among the three classifications (p = 0.001). The IB of carotid plaque obtained by iPlaque analysis was associated with its histologic characteristics. |
