BACKGROUND Magnetic resonance cholangiography (MRC) has gained popularity for diagnosing primary sclerosing cholangitis (PSC). We determined the accuracy of MRC compared with endoscopic retrograde cholangiography (ERC) for diagnosing PSC. MATERIALS AND METHODS This retrospective case-control study was conducted on patients referred to an outpatient gastroenterology clinic from 2001 to 2013. P...

BACKGROUND Methods of classifying chronic obstructive pulmonary disease (COPD) depend largely upon spirometric measurements but disability is only weakly related to measurements of lung function. With the increased use of pulmonary rehabilitation, a need has been identified for a simple and standardised method of categorising disability in COPD. This study examined the validity of the Medical R...

Obtaining eyewitness accounts after an event can aid criminal investigations. Mental Reinstatement of Context (MRC) is used to improve memory. However, direct comparisons have identified little effects MRC relative free delivery with No-MRC, and known about the on subjective memory characteristics role individual differences in autobiographical Here we exposed 234 participants a naturalistic fi...

OBJECTIVE The purpose of our study is to evaluate the success rate and feasibility of intraoperative neuromonitoring (IONM) focusing on transcranial motor evoked potential (TcMEP) monitoring for patients with preoperative motor weakness in spine surgery. METHODS Between November 2011 and December 2013, TcMEP and somatosensory evoked potential (SSEP) monitoring were attempted in 130 consecutiv...

Symbol error rate (SER) of quadrature subbranch hybrid selection/maximal-ratio combining (HS/MRC) scheme for 1-D modulations in Rayleigh fading under employment of the generalized receiver (GR), which is constructed based on the generalized approach to signal processing (GASP) in noise, is investigated. N diversity input branches are split into 2N inphase and quadrature subbranches. M-ary pulse...

Aiming at the MTF evaluation limitations in visible imaging system, this paper introduces the minimum resolvable contrast. On the basis of MRC theoretical, the paper obtains subjective and objective methods of MRC measurement. Then MRC measurement based on neural network is put forward, which does not depend on subjective judgment of person. BP neural network is established and trained. Therefo...

Magnetic resonance cholangiography (MRC) is a non-invasive imaging modality that has become widely available. In the short time since its introduction, MRC has been shown to possess excellent accuracy for the diagnosis of various biliary pathologies, including choledocholithiasis. Investigations of the clinical applications of MRC are ongoing. This review summarizes the diagnostic capabilities ...
