On Thursday, July 18th, the UR SPIE student chapter will be continuing its annual Summer Colloquium series.
Who: Etana Elegbe
What: Development of Single Tracking Location Acoustic Radiation Force Imaging (STL-ARFI) for the Assessment of Liver Fibrosis Progression
Date: 07/18/2013
Time: 11:30 am – 12:30 pm
Where: Sloan Auditorium (Goergen 101)
As a consequence of the liver’s great ability to increase its level of operation in response to the demands of an injury, there is often a significant latent period between the onset of the disease and the clinical symptomsexcept in the case of fulminant hepatic failure. At this point however, the disease is usually at an advanced stage and the damage is substantial. Progressive liver fibrosis is a common feature in the majority of chronic liver
disease cases. Therefore, liver fibrosis stage is considered to be of great prognostic value in the assessment of liver disease.
Several studies have shown that there is a connection between the liver tissue mechanical properties and liver fibrosis. Single Tracking Location Acoustic Radiation Force Imaging (STL ARFI) is an elastographic method that estimates shear wave speed, and thus shear modulus, by inducing shear waves in the tissue and tracking its propagation through the region of interest. STL ARFI uses a single tracking line and consequently suppresses
speckle-induced biases in the estimates of shear modulus. I will discuss STL ARFI as an elastographic technique and show some data demonstrating the feasibility of STL ARFI as a tool in the staging of liver fibrosis in vivo.
Bring your lunch! Snacks and beverages will be provided.
