Comparative Effectiveness of MR Enterography

2015-06-10 01:53:23 | BioPortfolio


The purpose of this study is to determine the efficacy of ultrasound imaging compared to MRE (Magnetic Resonance Enterography) a form of magnetic resonance imaging (MRI) in accurately diagnosing and following Small Bowel Crohn Disease (SBCD) in children.


Computed Tomography (CT) is an imaging tool that exposes patients to radiation, and until recently it was the most commonly used imaging method to evaluate small bowel Crohn disease. Recently, Magnetic Resonance Enterography (MRE) which is a form of magnetic resonance imaging that provides detailed images of the bowel and less frequently, Ultrasound (US) are replacing CT as the standard of care imaging tool at some institutions.

The investigators would like to determine how effective US imaging is compared to MRI imaging in accurately diagnosing and following SBCD in children. Along with enteric ultrasound (EnUS) we will also be comparing a new ultrasound technology called Ultrasound Elastography Imaging (UEI) for this study in which we will be using a second form of UEI called Acoustic Radiation Force Impulse (ARFI). This technique uses sound waves to asses the stiffness properties of soft tissue. The study will compare costs, patient preferences, and imaging accuracy.

Medical and Biotech [MESH] Definitions

The use of ultrasound to guide minimally invasive surgical procedures such as needle ASPIRATION BIOPSY; DRAINAGE; etc. Its widest application is intravascular ultrasound imaging but it is useful also in urology and intra-abdominal conditions.

The use of molecularly targeted imaging probes to localize and/or monitor biochemical and cellular processes via various imaging modalities that include RADIONUCLIDE IMAGING; ULTRASONOGRAPHY; MAGNETIC RESONANCE IMAGING; fluorescence imaging; and MICROSCOPY.

The use of combination of imaging techniques or platforms (e.g., MRI SCAN and PET SCAN) encompassing aspects of anatomical, functional, or molecular imaging methods.

A technique applicable to the wide variety of substances which exhibit paramagnetism because of the magnetic moments of unpaired electrons. The spectra are useful for detection and identification, for determination of electron structure, for study of interactions between molecules, and for measurement of nuclear spins and moments. (From McGraw-Hill Encyclopedia of Science and Technology, 7th edition) Electron nuclear double resonance (ENDOR) spectroscopy is a variant of the technique which can give enhanced resolution. Electron spin resonance analysis can now be used in vivo, including imaging applications such as MAGNETIC RESONANCE IMAGING.

Spectroscopic method of measuring the magnetic moment of elementary particles such as atomic nuclei, protons or electrons. It is employed in clinical applications such as NMR Tomography (MAGNETIC RESONANCE IMAGING).
