  • IntroductionTherapeutic hypothermia (TH), the intentional reduction of the body core temperature (Geurts et al. 2014), has long been applied as a neuroprotective measure during cardiac surgeries in humans and animals (Bigelow et al. 1950; Nathan et al. 2001; Aydemir et al. 2012). Other indications for TH include coronary artery bypass surgery…[Read more]

  • The purpose of this study was to evaluate diaphragmatic motion during tidal breathing in a standing position in a health screening center cohort using dynamic chest radiography in association with participants’ demographic characteristics.Materials and MethodsStudy PopulationThis cross-sectional study was approved by the institutional review…[Read more]

  • Pulmonary Function TestsThe pulmonary function tests were performed in all participants on the same day of the imaging study. Parameters of pulmonary function tests were measured according to the American Thoracic Society guidelines 20 ;  21 using a pulmonary function instrument with computer processing (DISCOM-21 FX, Chest MI Co, Tokyo,…[Read more]

  • Image AnalysisThe diaphragmatic motions on sequential chest radiographs (dynamic image data) during tidal breathing were analyzed using prototype software (Konica Minolta, Inc.) installed in an independent workstation (Operating system: Windows 7 Pro SP1; Microsoft, Redmond WA; CPU: Intel Core i5-5200U, 2.20 GHz; memory 16 GB). The edges of the…[Read more]

  • Materials and MethodsStudy PopulationThis cross-sectional study was approved by the institutional review board, and all the participants provided written informed consent. From May 2013 to February 2014, consecutive 220 individuals who visited the health screening of our hospital and met the following inclusion criteria for the study were…[Read more]
