Shape and texture analysis of the carotid plaque, and its correlation with cerebral infarctions on CT, and cerebrovascular symptoms

Abstract

This work has studied the relationship between ultrasonic texture characteristics, ultrasonic shape characteristics, cerebral infarctions on CT, and cerebrovascular symptoms, in an attempt to identify the unstable carotid plaque, i.e. the plaque associated with high prevalence of ipsilateral cerebral infarctions on CT, and cerebrovascular symptoms. The morphological features used were : the grey scale median (GSM) for the texture, and the bending energy (BE) for the shape. It has been shown that echoluscent plaques (plaques with low GSM) with irregular shape (high BE) are associated with high prevalence of ipsilateral cerebral infarctions on CT and cerebrovascular symptoms, whereas echogenic plaques (high GSM) with smooth shape (low BE) are associated with low prevalence of ipsilateral cerebral infarctions on CT and cerebrovascular symptoms. Previous work has demonstrated the significance of the GSM in identifying the unstable carotid plaques, but no attempt, to our knowledge, has been made to establish the clinical significance of the ultrasonic shape characteristics of the carotid plaque. The importance of the ultrasonic texture and shape characteristics will be established in prospective studies of patients with asymptomatic carotid plaques, aiming at the identification of patients with a high risk for stroke, and therefore for a better selection of asymptomatic  More>>
