BACKGROUND Contrast enhanced magnetic resonance cholangiography is a novel technique and promising method in demonstrating biliary tree anatomy and evaluating biliary disorders. However, to date, there are a limited number of studies that have focused on the impact of this technique. AIMS We aimed to evaluate the additional role of contrast enhanced MR cholangiography (MRC) and compare contra...

Selection combining (SC) and maximal ratio combining (MRC) with Low Density Parity-check (LDPC) enhance the performance of overall system by providing coding gain. Using Gaussian approximation (GA) approach the bit error rate of LDPC-SC, LDPC-MRC system is derived for BPSK modulation over an independent and identically distributed (i.i.d) Rayleigh fading channel. The analysis is done for the ca...

Ruehm University Hospital Essen, 45122 Essen, NRW, Germany, Department of Radiology, Crete, Crete, Greece ABSTRACT: The aim of this study was to assess MR colonography for the detection of colonic polyps/malignancy. 50 subjects underwent MR colonography prior to conventional colonoscopy. MRC is based on a rectal enema with water in c...

This chapter unifies the principles and analyses of conventional signal processing algorithms for receive-side smart antennas, and compares their performance and numerical complexity. The chapter starts with a brief look at the traditional single-antenna optimum symbol-detector, continues with analyses of conventional smart antenna algorithms, i.e., statistical beamforming (BF) and maximal-rati...

Background and Aims: Adventitious agents, especially viral agents are among the most important concerns in viral vaccines. Viral contamination of biological products may arise from the original source of the reagents such as, serum, trypsin, animal or human derived media components or cell culture and working seed or cross contamination of vaccine during production. In this study, adventitious ...

June 30, 1986 When Bouroncle and colleagues’ described hairy cell leukaemia as a distinct type of human leukaemia, the methodology for characterising the membrane phenotype of lymphocytes was not yet available. The peculiar morpholo~yofthe hairy cell with its long cytoplasmic villi, well demonstrated by phase contrast microscopy, had some resemblance with that of histiocytes as seen in tissue s...

BACKGROUND AND OBJECTIVE It is unclear whether the severity of functional limitation resulting from IPF affects the response to pulmonary rehabilitation. The aim of this study was to compare the outcomes of rehabilitation in patients with IPF, who were grouped according to the Medical Research Council (MRC) dyspnoea scale. METHODS Sixty-five subjects (46, 71% men) with stable IPF were enrolle...
