Comparison of MRI, CT and 18F-FDG PET/CT in the diagnosis of local and metastatic of nasopharyngeal carcinomas: an updated meta analysis of clinical studies.

Background: A meta-analysis was conducted to evaluate the accuracy of MRI, CT and FDG PET/CT in TNM stage of nasopharyngeal carcinoma patients (NPC).

Methods: Through a search of studies from 1996 to April 2015, pooled estimated sensitivity, specificity, pooled diagnostic odds ratio (DOR), summary receiver operating characteristic (SROC) curves and Q*-index were calculated.

Results: Totally 23 studies were included for analysis.

Piperine attenuates lipopolysaccharide (LPS)-induced inflammatory responses in BV2 microglia.

Piperine, the chief alkaloid isolated from Piper nigrum, has been known to have anti-inflammatory effect. However, the effects of piperine on neuroinflammation have not been reported. In the present study, we evaluated the effects of piperine on neuroinflammation in BV2 microglia and investigated the molecular mechanism.

Diagnostic Value of Magnetic Resonance Spectroscopy in Radiation Encephalopathy Induced by Radiotherapy for Patients with Nasopharyngeal Carcinoma: A Meta-Analysis.

In this study, articles in English and Chinese were selected from available electronic databases prior to September 2014. The metabolic concentrations and patterns of N-acetylaspartic acid (NAA), Choline (Cho), Creatine (Cr), NAA/Cr, NAA/Cho, and Cho/Cr ratios in radiotherapy-induced radiation encephalopathy by proton magnetic resonance spectroscopy were extracted. A meta-analysis was performed to quantitatively synthesize findings of these studies.

Diffusion tensor imaging study on radiation-induced brain injury in nasopharyngeal carcinoma during and after radiotherapy.

Aims And Background: The aim of this study was to monitor the mircostructure change of temporal lobe during the acute and subacute stage of radiation-induced brain injury using magnetic resonance diffusion tensor imaging (DTI) in nasopharyngeal carcinoma patients.

Methods And Study Design: Eighty patients diagnosed with nasopharyngeal carcinoma and treated with the first radiotherapy from July 2010 to May 2012 were enrolled. Routine brain magnetic resonance imaging (MRI) and DTI were conducted in all patients before and during radiotherapy (radiation dose was 20, 40, and 60 Gy, respectively).

MRI characteristics and follow-up findings in patients with neurological complications of enterovirus 71-related hand, foot, and mouth disease.

Objectives: This study aimed to investigate the magnetic resonance imaging (MRI) characteristics and clinical and MRI follow-up findings of patients with neurological complications of enterovirus 71-related hand, foot and mouth disease.

Methods: Data were collected from 12 patients who developed neurological complications of enterovirus 71-related hand, foot, and mouth disease during an enterovirus-71 outbreak in Hainan Province, China, from May 2008 to October 2011. Patients were followed up for 2 years.

Eccentric development of Balo's concentric sclerosis: detected by magnetic resonance diffusion-weighted imaging and magnetic resonance spectroscopy.

Background: The concentricity of BCS has captured wide attention; the findings of the current study may provide useful information on the centrifugal pathogenesis of BCS.

Objective: This study aims to evaluate the performance of MRI, DWI and MRS in elucidating the pathogenesis of Balo's lesions expanding.

Methods: Six clinically diagnosed BCS cases were reviewed, and the findings obtained by MRI, DWI and MRS were analyzed.
