COMPARISON OF TISSUE VELOCITY AND STRAIN IN NORMAL BRAIN AND GLIAL TUMORS AS QUANTIFIED BY PROCESSING OF ULTRASOUND DATA.

摘要

The purpose of the study was to investigate whether or not a) tissue velocity and b) strain as calculated from ultrasound RF data using a previously described method is able to differentiate between glial tumors and normal brain tissue. We have quantified tissue velocity and strain in brain by processing ultrasound RF data acquired in vivo from 16 patients with glial tumors. Our results indicate that tissue velocity is not a suitable parameter to discriminate between glial tumors and normal brain tissue. However, strain is a tissue parameter that can be used to differentiate between pathological and normal brain tissue.
