Overhauser-enhanced magnetic resonance elastography

Arnaud Comment, Najat Salameh

Magnetic resonance elastography (MRE) is a powerful technique to assess the mechanical properties of living tissue. However, it suffers from reduced sensitivity in regions with short T-2 and T-2* such as in tissue with high concentrations of paramagnetic i ...

Low-Cost High-Performance MRI

Najat Salameh

Magnetic Resonance Imaging (MRI) is unparalleled in its ability to visualize anatomical structure and function non-invasively with high spatial and temporal resolution. Yet to overcome the low sensitivity inherent in inductive detection of weakly polarized ...

Hyperpolarization without persistent radicals for in vivo real-time metabolic imaging

Mor-Miri Mishkovsky, Christophe Roussel, Andrea Capozzi, Jean-Noël Hyacinthe, Tian Cheng, Arnaud Comment, Najat Salameh, Yuhei Takado, Tim Rolf Eichhorn

Hyperpolarized substrates prepared via dissolution dynamic nuclear polarization have been proposed as magnetic resonance imaging (MRI) agents for cancer or cardiac failure diagnosis and therapy monitoring through the detection of metabolic impairments in v ...

High intensity focused ultrasound for transcranial therapy of brain lesions and disorders

Yves Martin, Najat Salameh, Benjamin Robert

A novel MR-guided brain therapy device operating at 1 MHz has been designed and constructed. The system has been installed and tested in a clinical 1.5 T Philips Achieva MRI. Skull bone distortions induced on the ultrasonic beam are corrected using the con ...

The purpose of this study was to prospectively compare the performance of magnetic resonance (MR) elastography using echo-planar and spin-echo imaging for staging of hepatic fibrosis. Twenty-four patients who had liver biopsy for suspicion of chronic liver ...

2008

The purpose of our study was to prospectively compare the success rate and diagnostic accuracy of magnetic resonance elastography, ultrasound elastography, and aspartate aminotransferase to platelets ratio index (APRI) measurements for the noninvasive stag ...

Liver fibrosis: non-invasive assessment with MR elastography

Najat Salameh

The aim of this study was to assess the feasibility of using non-invasive MR elastography for determining the stage of liver fibrosis. Twenty-five consecutive patients who had liver biopsy for suspicion of chronic liver disease were included in the study. ...
