BACKGROUND Evaluation of pregnant women with known or suspected Crohn's disease (CD) remains a challenge. Magnetic Resonance Enterography (MRE) is a promising diagnostic tool in these patients; however, the clinical data on MRE utilization in pregnancy is scarce. The aim of the study was to describe the experience with MRE in pregnant CD patients in a tertiary referral center. METHODS We retr...

Introduction: MRE measures tissue stiffness, which reflects the underlying structural organization of cells, extracellular matrix, and capillaries. Diffusion MRI measures the apparent diffusion coefficient (ADC), which describes the random motion of water molecules in both the intraand the extra-cellular compartments. Both MRE and diffusion MRI are used for detecting diseases in soft biological...

BACKGROUND The aim was to evaluate and compare the diagnostic performance of magnetic resonance enteroclysis (MRE) and wireless video capsule endoscopy (CE) in detecting and classifying small bowel Crohn's disease (CD) proximal to the terminal ileum. METHODS Nineteen patients with histologically proven CD (M:F = 13:6; mean 34 years, range 17-65) were prospectively included in the study when p...

background: according to recent studies comparing magnetic resonance enterography (mre) with ileocolonoscopy for assessing inflammation of small bowel and colonic segments in adults with active crohn’s disease (cd), we aimed to compare the accuracy of these two diagnostic methods in iranian population. method: during 2013-2014 a follow-up study was done on 30 patients with active cd ina gastroe...

PURPOSE The goal of this study was to compare magnetic resonance enterography (MRE) and video capsule endoscopy (VCE) in suspected small bowel disease. MATERIALS AND METHODS Nineteen patients with suspected small bowel disease participated in a prospective clinical comparison of MRE versus VCE. Both methods were evaluated separately and in conjunction with respect to a combined diagnostic end...

BACKGROUND/AIMS To assess the sensitivity of magnetic resonance enterography (MRE) in the diagnosis of Crohn's disease (CD) activity and correlation between endoscopic and MRE scores in predicting the activity grade. MATERIALS AND METHODS Twenty-five ileal CD patients with clinical and biochemical evidence of activation underwent ileocolonoscopy and MRE within 7 days of their application. Sim...

To rationally design a productive heterologous biosynthesis system, it is essential to consider the suitability of foreign reactions for the specific endogenous metabolic infrastructure of a host. We developed a novel web server, called MRE, which, for a given pair of starting and desired compounds in a given chassis organism, ranks biosynthesis routes from the perspective of the integration of...

Most Relevant Explanation (MRE) is a new approach to generating explanations for given evidence in Bayesian networks. MRE has a solution space containing all the partial instantiations of target variables and is extremely hard to solve. We show in this paper that the decision problem of MRE is NP -complete. For large Bayesian networks, approximate methods may be the only feasible solutions. We ...

In the uplink channel of the 3GPP long term evolution (LTE) and LTEAdvanced (LTE-A) systems, signal carrier frequency-division multiplexing access (SC-FDMA) transmission scheme is employed instead of orthogonal frequency-division multiplexing (OFDM) to reduce the peak-to-average power ratio (PAPR). However, compared to OFDM, SC-FDMA has lower channel throughput, since it suffers from inter-symb...

The mechanical properties of liver can sensitively indicate the progression of hepatic fibrosis. Mechanical tissue characterization involves the analysis of the complex shear modulus measured either by oscillatory rheometry or by in vivo elastography. In this study, bovine liver specimens were investigated by oscillatory rheometry and multifrequency magnetic resonance elastography (MRE) in a co...
