      First and second order statistical texture features in carotid plaque image analysis: preliminary results from ongoing research. 

      Kyriacou, Efthyvoulos C.; Nicolaïdes, Andrew N.; Pattichis, Constantinos S.; Petroudi, Styliani; Pattichis, Marios S.; Griffin, Maura B.; Kakkos, Stavros K.; Makris, Gregory C. (2011)
      Carotid plaques have been associated with ipsilateral neurological symptoms. High-resolution ultrasound can provide information not only on the degree of carotid artery stenosis but also on the characteristics of the ...
