OBJECTIVES We aim to develop an imaging technique for visualization of the Eustachian tube (ET) lumen. STUDY DESIGN A prospective, experimental study in an animal model and in human cadaver specimens. METHODS Applying iodixanol to the middle ear in two human temporal bone specimens, followed by computed tomography (CT) examinations, we optimized contrast dilution, CT algorithm, and head pos...

BACKGROUND AND PURPOSE A CT scanner employing a digital flat-panel detector is capable of very high spatial resolution as compared with a multi-section CT (MSCT) scanner. Our purpose was to determine how well a prototypical volume CT (VCT) scanner with a flat-panel detector system defines fine structures in temporal bone. METHODS Four partially manipulated temporal-bone specimens were imaged ...

Oriented strand board (OSB) is an important engineered wood product manufactured through bonding of strands in cross-oriented layers. The bending strength, one the crucial properties for loadbearing material, OSB strongly depends on its structural characteristics. To understand strength OSB, strain distribution was continuously monitored during a three-point test using digital image correlation...

background and aims. the imaging techniques commonly used for foreign body detection include plain radiography, xeroradiography, computed tomography (ct) scans, magnetic resonance imaging (mri) and ultrasonography. the aim of the present study was to compare cone-beam computed tomography (cbct) with conventional ct scan in determination of the exact location of a foreign body in the maxillofaci...

the c7-ras 6/061-004 training course by the international atomic energy agency/regional cooperative agreement (iaea/rca) was held in chiba in 2014. the syllabus, pre- and post-course evaluations, and survey questionnaire results were assembled in this course. the post-course evaluation, including 32 questions similar to the pre-course evaluation, was performed right after the end of the final e...

This study investigated the effects of silver diamine fluoride (SDF) and potassium iodide (KI) treatments on acid resistance dentin exposed to secondary caries. Sixteen bovine specimens with artificially induced caries were assigned following four groups: untreated negative control, positive SDF-treated (SDF), SDF KI-treated (SDFKI). Multispecies cariogenic biofilms containing <i>Streptoc...

OBJECTIVES If the Chlamydia trachomatis (CT) bacterial load is higher in high-risk populations than in the general population, this negatively affects the efficacy of CT screening incentives. In the largest retrospective study to date, we investigated the CT load in specimens collected from 2 cohorts: (1) attendants of a sexually transmitted infection (STI)-clinic and (2) participants of the Du...

Background‘ACROSIS COVID-19 A g (NPS)’ kit (SG Medical, Seoul, Korea) is a newly developed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antigen-detection rapid diagnostic test (Ag-RDT) using surface-enhanced Raman scattering (SERS)-based lateral flow immunoassay (LFIA). We evaluated its clinical performance compared with STANDARD Q (SD Biosensor, Suwon, Korea), previously approv...

Aim: The aim of the study is to investigate whether there a correlation between severity pneumonia and fatty liver disease in COVID-19. Material Method: In this chest computed tomography (CT) images 168 patients who were confirmed be COVID-19 positive according nasopharyngeal swab specimens evaluated. presence hepatic steatosis evaluated on CT images.Results: aged 26 89, mean age was 63.6 ± 12....

The behavior of two series corroded thin-walled concrete-filled steel tubes (CFSTs) was investigated in this paper. One series, called the CT consists fourteen CFST specimens by NaCl solution, while other, AT six test pieces atmosphere. Outer surfaces were scanned using a 3D scanner machine, and complete surface profile each specimen obtained for corrosion evaluation different methods study. En...
