A group of 34 proven cases of pulmonary sarcoidosis was investigated by computed tomography (CT) to determine whether CT provided any information beyond that obtained from conventional chest films. Computed tomography disclosed a surprisingly high prevalence of minor pleural changes in sarcoidosis, including two patients with small pleural effusions. Unsuspected bullae and isolated "granulomatous" nodules were additionally demonstrated. Increases in lung density and alterations in gravity dependent vascular perfusion were assessed; these may reflect alterations in the vascular bed, and the increased density is possibly due to diffuse invasion of the lung not recognizable by conventional chest X-ray films. Tracheal compression was noted in one case and vertebral densities in three. Prominence of "small air spaces" was recorded in four patients; the nature of the pathology responsible for this finding is at present speculative. While not replacing conventional chest radiography, CT does make a definite contribution to the assessment of pulmonary sarcoidosis.
对34例经证实的肺结节病患者进行了计算机断层扫描（CT）检查，以确定CT是否能提供超出传统胸部X线片的信息。CT显示结节病患者中轻微胸膜改变的发生率出奇地高，包括2例有少量胸腔积液的患者。此外，还发现了未被怀疑的肺大疱和孤立的“肉芽肿性”结节。评估了肺密度增加和重力依赖区血管灌注的改变；这些可能反映了血管床的改变，密度增加可能是由于传统胸部X线片无法识别的肺部弥漫性浸润。1例患者出现气管受压，3例出现椎体密度改变。4例患者记录到“小气道”突出；造成这一发现的病理性质目前尚属推测。虽然CT不能取代传统的胸部X线摄影，但它确实对肺结节病的评估有明确贡献。
