MR elastography of stroke: A feasibility study

MR-Elastography of the prostate using an endorectal coil for actuation - a feasibility study

MR elastography following focused ultrasound treatment of uterine fibroids

Background Magnetic Resonance Elastography (MRE) is a technique in which shear waves are induced in soft tissues and are imaged by Magnetic Resonance (MR) is to assess tissue stiffness. While gadolinium has served as the standard for assessing immediate post treatment changes in the fibroids, some patients may have allergies to gadolinium preventing use of this contrast agent. Additionally, som...

Prostate MRE at 3T: Trans-perineal wave propagation

Introduction There has been a great interest in applying Magnetic Resonance Elastography (MRE) to quantify the visco-elastic properties of the prostate in-vivo, with the goal of imaging prostate cancer. Current MRE methods [1-3] have limitations with acquiring high-SNR motion encoded MR-signals at 1.5T, and inducing shear waves of sufficient amplitude into the prostate reliably and in a patient...

Feasibility and practicality of MR imaging of stroke in the management of hyperacute cerebral ischemia.

BACKGROUND AND PURPOSE Neuroimaging techniques such as diffusion- and perfusion-weighted MR imaging have been proposed as tools for advanced diagnosis in hyperacute ischemic stroke. There is, however, substantial doubt regarding the feasibility and practicality of applying MR imaging for the diagnosis of stroke on a routine basis, especially with respect to possible delay for specific treatment...

Single radiofrequency source for MR and hyperthermia studies

Hyperthermia is an experimental/adjuvant therapeutic modality for cancer. Combining hyperthermia with the non-invasive metabolic studies using magnetic resonance (MR) is an interesting area of research and can provide useful information. In this paper, feasibility of using the same radio frequency source for carrying out combined hyperthermia and MR studies is demonstrated. A conventional RF hy...
