本研究的目的是显示慢性阻塞性肺疾病（COPD）患者的MR荧光透视检查可减少肺动脉偏移，并将结果与肺功能检查（PFT）进行比较。该研究包括13名男性和10名女性（平均年龄56.2岁）COPD患者，以及9名男性和6名女性（平均年龄55.8岁）作为对照组。在深吸气和呼气期间获得具有破坏的连续回波脉冲序列的MR透视图像。检查后，通过电影环显示，识别隔膜的最高和最低位置，并测量偏移距离。比较了患者和健康受试者之间的脑电偏移差异。我们还比较了MR透视结果与PFT。在两组中的每个人中，隔膜的偏移在电影环显示中被清楚地显示。膈肌最深点和最高点偏移量之差，患者组左右侧平均分别为26和20mm，健康组分别为69和56mm。1s呼气量与MR透视结果之间存在显著相关性。磁共振透视研究显示COPD患者与健康人之间的磁共振偏移有显著性差异。1s呼气量与呼气峰速密切相关。MR荧光透视似乎是显示横隔膜偏移的一种有用方法。(C)2001 Elsevier Science Inc.

The aim of this study was to show reduction of the diaphragmatic excursion with MR fluoroscopy in patients with chronic obstructive pulmonary disease (COPD) and to compare the results with pulmonary function test (PFT). The study included 13 men and 10 women (average age 56.2) with COPD, and 9 men and 6 women (average age 55.8) as a control group. MR fluoroscopy images with Spoiled Gradient-echo pulse sequence was obtained during deep inspiration and expiration. After examination, over cine-loop display, the highest and lowest positions of the diaphragm were identified and the distance of excursion was measured. Differences in the diaphragmatic excursion between patient and healthy subjects were compared. We have also compared MR fluoroscopy results with PFT. In each person of both groups, excursion of the diaphragm was demonstrated clearly in cine-loop display. Differences of excursion between deepest and highest point of diaphragm were on average 26 and 20 mm, respectively, in the right and left side in patients and 69 and 56 mm in healthy group. Significant correlation was found between expiratory volume in 1 s and MR fluoroscopy results. MR fluoroscopy study showed that there were significant statistical differences in diaphragmatic excursion between patients with COPD and healthy subjects. Expiratory volume in 1 s is closely associated with the diaphragmatic excursion. MR fluoroscopy would seem to be a useful method for showing diaphragmatic excursion. (C) 2001 Elsevier Science Inc.
