Real-time Elastosonography for the Assessment of the Stiffness of Carotid Plaques in Stroke Patients

Objective] To explore the real-time elastosonography for the assessment the stiffness of carotid plaques in stroke patients. Methods] The low-echo plaques, hypoechogenicity plaques and strong-echo plaques in 53 stroke patients were found by gray scale ultrasound. Meanwhile, real-time elastosonography was used to calculate the ratio of the stiffness of carotid wall to different types of echo plaques. Results] Thirty-one low-echo plaques, thirty-seven hypoechogenicity plaques and thirteen calcified plaques were found by routine ultrasound. Real-time elastosonography showed that the low-echo plaques were mainly yellow-green or green, and hypoechogenicity plaques were mosaic of green and blue, and the strong-echo plaques were blue. The stiffness ratio of lowecho plaques, hypoechogenicity plaques, strong-echo plaques increased by turns. The stoke patients with the stiffness ratio of carotid plaque less than 5.0 occupied 73.4% （41/53）. Conclusion] Real-time elastosonography for calculating the stiffness ratio of carotid plaques is helpful for assessing the stability of carotid plaques in stroke pa- tients.
