One of the characteristic biological effects of the inhaled asbestos dust is the formation of hyaline thickenings on all pleurae in the form of plaques, in which calcium could be deposited. Due to the difficulties in the differentiation of the pleural hyalinosis with the conventional X-ray methods, the authors studied the potentialities of echography in 18 patients in contact with asbestos. They used two apparatuses (type "grey scale" 3401 of the firm (Brüel & Kjaër with linear scanning and "Siam" with sector scanning). Echography could establish areas of thickening on the parietal and diaphragmatic pleurae, to determine their thickness in micron and the degree of echogenicity. The comparison with the X-ray examination of the chest (face and I oblique position, lowvoltage technique) showed a positive finding with both methods in 7, suspicious X-ray finding with positive echography--in I, positive finding only with echography--in 6 and negative by both methods--in 4 subjects. The echographic examination on pleura is a rapid, cheap and harmless method, contributing not only to the early detection of its asbestosis lesions but to the elucidation of the etiology of pulmonary fibrosis.
吸入石棉粉尘的典型生物学效应之一是在所有胸膜上形成斑块状透明增厚,其中可能会有钙沉积。由于用传统X射线方法鉴别胸膜透明变性存在困难,作者对18名接触石棉的患者进行了超声检查潜力的研究。他们使用了两台仪器(Brüel & Kjaër公司的“灰阶”3401型,线性扫描,以及“Siam”型,扇形扫描)。超声检查能够确定壁层胸膜和膈胸膜增厚的区域,测量其以微米为单位的厚度以及回声强度。与胸部X线检查(正位和第一斜位,低电压技术)比较,两种方法均呈阳性结果的有7例,X线检查可疑但超声检查阳性的有1例,仅超声检查阳性的有6例,两种方法均为阴性的有4例。胸膜超声检查是一种快速、廉价且无害的方法,不仅有助于早期发现石棉沉着病病变,还有助于阐明肺纤维化的病因。
