在61例连续的气流阻塞评估患者中，X线平片上肺中带血管直径的测量值与转移因子（CO弥散量）之间存在显著的线性关系（r = 0.46，P < 0.001）。由于转移因子的降低已被证明与结构性肺气肿有关，因此中区血管口径的降低也意味着相同的结果。在个体患者中，无论是转移因子还是结构性肺气肿都不能仅从中间区血管直径可靠地预测。
In a group of 61 consecutive patients undergoing assessment of air flow obstruction, a significant linear relation was demonstrated between measurements of the diameter of the midzonal pulmonary vessels on the plain chest radiographs and transfer factor (diffusing capacity for CO) (r = 0.46, P < 0.001). Since reduction in transfer factor has been shown to relate to structural emphysema, reduction in midzone vessel caliber implies the same. In the individual patient neither the transfer factor nor structural emphysema can be reliably predicted from midzone vessel diameters alone.
