本文的目的是确定CT(电子计算机体层摄影)能否在早期石棉沉着症中确定胸膜和肺实质的疾患。以及应用CT对曾与石棉尘接触的病人中能否得到更多资料。这种方法特别适宜于工业尘肺检查,使X线发现得以相互补充。早期石棉肺一直被认为难以诊断。如众所周知,用力性呼吸困难及气体转移因子受损时,常规X线片上沒有任何改变。尸检所见胸膜钙化斑证实:X线所见仅及大约15％。很显然,一种早期的
The purpose of this paper is to determine if CT (computed tomography) can determine the pleura and lung parenchyma in early asbestosis. As well as whether CT can be used to get more information on patients who have been in contact with asbestos dust. This method is particularly suitable for industrial pneumoconiosis, X-ray findings to complement each other. Early asbestosis has been considered difficult to diagnose. As is well-known, there is no change in conventional X-ray film when forced dyspnea and gas transfer factor are impaired. Pleural findings of calcification plaque confirmed: only about 15% of X-ray findings. Obviously, an early one
