  • 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 purchase ARQ 621 dose is much lower than that of CT. Also, whereas CT and MRI are performed…[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 methylergometrine on the radiograph at the resting end-expiratory position. These points…[Read more]
