Accuracy Evaluation and Comparison of 14 Diagnostic Markers for Nasopharyngeal Carcinoma: A Meta-Analysis.

The aim of the present study was to collect published studies and compare the diagnostic accuracy of different markers for nasopharyngeal carcinoma (NPC). We systematically searched PubMed/MEDLINE, EMBASE, Cochrane Library, CNKI, and Wanfang for relevant studies until April 29, 2020. The revised Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) tool was used to evaluate the methodological quality of the studies.

Adverse effects of semicircular circle angles variation on Epley repositioning procedure: a study on reconstruction of Micro-CT images 3D.

For patients with posterior semicircular canal (PSC) BPPV, Epley re-position maneuver and some improvement methods are the most efficient treatment methods. But there were still 9.43% patients who were not benefit from Epley re-position maneuver.

Anatomical Variations of the Human Cochlea Determined from Micro-CT and High-Resolution CT Imaging and Reconstruction.

Understanding the anatomical variations in the human cochlea is important for cochlear implants. This study examined these variations using a reconstructed fusion model of the skull and temporal bone. The three-dimensional (3D) digital model of the temporal bone was reconstructed from multiple axial micro-computed tomography (CT) scans of temporal bone and high resolution CT of the skull from 15 cadavers.
