当院にて、肺癌、肝臓など横隔膜近傍の腹部腫瘤などの確定診断または治療のために手術を受けた患者。これらの術後に主治医が経過観察のため X 線撮影、CT、核医学検査などの追加画像検査が必要と判断した患者。
Around 4 weeks from the day of performing dynamic X-ray radiography, there is a history of any or all consultations such as nuclear medicine examination, CT, respiratory function examination (including scheduled) , and after surgical operation, who are determined to take that additional imaging such as X-rays, CT, and nuclear medicine exam.
Although case enrollment was relatively steady until July 2019, after the outbreak of the COVID-19 outbreak, it became difficult to perform respiratory function tests or imaging with large breaths, and additional cases were difficult to enroll after the last case on February 19, 2020. Thereafter, due to the spread of COVID-19 and the failure of the prototype machine, no new cases were added. Among these patients, 12 had obstructive ventilatory failure and 28 had normal pulmonary function, and their individual respiratory function and airway diameter data on dynamic images were analyzed. The mean age was 64 years, 31 males and 9 females.

動的胸部 X 線撮影装置を用いて、閉塞性換気障害のある 12 名と肺機能正常の 28名を対象に検討した結果、閉塞性換気障害を有する被験者では、健常者に比べて気管径が有意に狭窄していた(P < 0.01)。被験者を狭窄群(気管狭窄率[TNr]=41.5±7.7%、n=9)と非狭窄群(TNr=9.1±7.0%、n=31、p<0.01)に分けると、FEV1%-G、%V25 は狭窄群で非狭窄群より有意に小さかった(p<0.01)。
Using a dynamic chest radiography system, 12 subjects with obstructive ventilatory disorders and 28 subjects with normal pulmonary function were studied. The tracheal diameter was significantly stenosed in subjects with obstructive ventilatory disorders compared to normal subjects (P < 0.01).When the subjects were divided into a stenosis group (tracheal stenosis rate(TNr)= 41.5 +- 7.7%, n = 9) and a non-stenosis group (TNr= 9.1 +- 7.0%, n = 31, p < 0.01), FEV1%-G and %V25 were significantly smaller in the stenosis group than in the nonstenosis group (p < 0.01).
