Conventional approaches for MR elastography (MRE) using surface drivers have difficulty achieving sufficient shear wave propagation in the prostate gland due to attenuation. In this study we evaluate the feasibility of generating shear wave propagation in the prostate gland using a transurethral device. A novel transurethral actuator design is proposed, and(More)
The objectives of this study were to evaluate the feasibility of using a rigid radio-frequency receiver endorectal coil for intracavitary prostate magnetic resonance elastography (MRE) and to demonstrate the capability of this technique for generating stiffness maps over a typical prostate volume. An endorectal coil is currently used to help improve the(More)
PURPOSE To investigate the tolerability and technical feasibility of performing endorectal MR elastography (eMRE) in human volunteers within the representative age group commonly affected by prostate cancer. MATERIALS AND METHODS Endorectal MRE was conducted on seven volunteers in a 1.5 Tesla (T) MR imager using a rigid endorectal coil. Another five(More)
Styrene Butadiene Rubbers (SBRs) are among the most useful synthetic rubbers which can be produced by two different methods of polymerization: emulsion and solution. These two polymerization methods lead to different final properties. In general, SBRs produced by the solution method (S-SBRs) have narrower Molecular Weight Distribution (MWD), higher content(More)
Introduction: The stiffness of malignant prostate tissue is elevated as compared to normal or benign tissue, which suggests that the biomechanical properties of prostate tissue may be an independent marker for prostate cancer. Using dynamic MR elastography, micrometer amplitude shear waves are propagated into tissue, and the resulting tissue displacements(More)
Tissue stiffness is known to undergo alterations when affected by prostate cancer and may serve as an indicator of the disease. Stiffness measurements can be made with magnetic resonance elastography performed using a transurethral actuator to generate shear waves in the prostate gland. The goal of this study was to help determine the imaging requirements(More)
