  • Our study demonstrated that the average excursions of the bilateral MG 149 during tidal breathing (right: 11.0 mm, 95% CI 10.4 to 11.6 mm; left: 14.9 mm, 95% CI 14.2 to 15.5 mm) were numerically less than those during forced breathing in previous studies using other modalities 2; 7 ;  8. Using fluoroscopy, Alexander reported that the average…[Read more]

  •  A representative video of sequential chest radiographs obtained by chest dynamic radiography for the motion of the diaphragms (“dynamic X-ray phrenicography”). A board-certified radiologist placed a point of interest (red point) on the highest point of each order DMH-1 on the radiograph at the resting end-expiratory position. These points were…[Read more]

  • Recently, dynamic chest radiography using a flat panel detector (FPD) system with a large field of view was introduced for clinical use. This technique can provide sequential chest radiographs with high temporal resolution during respiration (17), and the clemastine fumarate dose is much lower than that of CT. Also, whereas CT and MRI are…[Read more]

  • Imaging Protocol of Dynamic Chest Radiology (“Dynamic X-Ray Phrenicography”)Posteroanterior dynamic chest radiography (“dynamic X-ray phrenicography”) was performed using a prototype system (Konica Minolta, Inc., Tokyo, Japan) composed of an FPD (PaxScan 4030CB, Varian Medical Systems, Inc., Salt Lake City, UT, USA) and a pulsed X-ray generator…[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]
