AIM To evaluate the utility of 3D-magnetic resonance cisternography(MRC) of posterior cranial fossa in visualizing trigeminal neurovascular compression in patients with trigeminal neuralgia. MATERIAL AND METHODS 146 consecutive patients in the period from June 2010 to July 2011 in our institute diagnosed with trigeminal neuralgia underwent MRC on the posterior cranial fossa. MR devices used f...

We performed a dynamic study of arachnoid cysts (ACs) using magnetic resonance cisternography (MRC) and proposed a classification of ACs.Twenty-three suitable patients in our hospital entered into this study according to our inclusion criteria. MRC images were collected in all the subjects at 1 and 24 hours after the administration of intrathecal gadolinium-diethylenetriamine penta-acetic acid ...

BACKGROUND AML with myelodysplasia related changes (AML MRC) is known to show a poor prognosis compared with de novo AML, but controversies exist about the prognostic impact of multilineage dysplasia (MLD) among MRC. We investigated the prognostic impact of MLD in AML MRC. METHODS A total of 357 patients newly diagnosed as AML at Asan Medical Center from January 2001 to December 2005 were ana...

OBJECTIVE To investigate whether motor evoked potential (MEP) amplitude ratio measurements are sufficiently objective to assess functional activities of the extremities. We also delineated the distribution between the presence or absence of MEPs and the Medical Research Council (MRC) scale for muscle strength of the extremities. METHODS We enrolled 183 patients with first-ever unilateral hemi...

BACKGROUND The value of magnetic resonance cholangiography (MRC) in assessing potential adult-to-adult living liver transplant (ALDLT) donors remains poorly defined. The purpose of this study is to determine the accuracy of MRC in assessing biliary anatomy with intraoperative confirmation. METHODS A prospective cohort of 30 ALDLT donors who underwent right hepatectomy from October 2000 to Jul...

The application of crop residue has become increasingly important for providing a barrier against water and wind erosion and improving soil organic matter content, infiltration, evaporation, temperature, and soil structure. The objectives of this work were to: (i) estimate maize residue cover (MRC) from Landsat-8 OLI images using seven vegetation indices (VIs) and eight textural features; and (...

This paper will describe the Mixed Raster Content (MRC) method for compressing compound images, containing both binary text and continuous-tone images. A single compression algorithm that simultaneously meets the requirements for both text and image compression has been elusive. MRC takes a different approach. Rather than using a single algorithm, MRC uses a multi-layered imaging model for repr...
