Conditional Stability for Single Interior Measurement

, 2013
An inverse problem to identify unknown coefficients of a partial differential equation by a single interior measurement is considered. The equation considered in this paper is a strongly elliptic second order scalar equation which can have complex ...

Excitation System for Magnetic Resonance Elastography Using Micro MRI

Journal of Biomechanical Science and Engineering, 2012
Magnetic resonance elastography (MRE) is a nondestructive method for measuring the hardness and softness of living tissue by means of magnetic resonance imaging (MRI) coupled with mechanical excitation of the subject.

Imaging biomarkers for steatohepatitis and fibrosis detection in non-alcoholic fatty liver disease [PDF]

, 2016
There is a need, in NAFLD management, to develop non-invasive methods to detect steatohepatitis (NASH) and to predict advanced fibrosis stages. We evaluated a tool based on optical analysis of liver magnetic resonance images (MRI) as biomarkers for NASH ...

Spring-damper equivalents of the fractional, poroelastic, and poroviscoelastic models for elastography

, 2017
In MR elastography it is common to use an elastic model for the tissue's response in order to properly interpret the results. More complex models such as viscoelastic, fractional viscoelastic, poroelastic, or poroviscoelastic ones are also used.

Impact of right-sided breast cancer adjuvant radiotherapy on the liver

Radiology and Oncology
In patients with right-sided breast cancer the liver can be partially irradiated during adjuvant radiotherapy (RT). We aimed to determine breast cancer RT effects on liver using with magnetic resonance elastography (MRE) and biological results.

The Role of Imaging Techniques in the Evaluation of Extraglandular Manifestations in Patients with Sjögren’s Syndrome

Diagnostics
Sjögren’s syndrome is a chronic autoimmune disease marked by lymphocytic infiltration of the exocrine glands and the development of sicca symptoms, yet some patients also develop extraglandular involvement.

Quantitative photoacoustic elastography in humans [PDF]

, 2016
We report quantitative photoacoustic elastography (QPAE) capable of measuring Young’s modulus of biological tissue in vivo in humans. By combining conventional PAE with a stress sensor having known stress–strain behavior, QPAE can simultaneously measure ...
