[Study on X-ray division type of pneumoconiosis-tuberculosis]

By analyzing the chest X-ray films of 805 cases of pneumoconiosis-tuberculosis patients, the authors suggested that the patients could be classified into 6 different types, which were infiltrative, conglomerating, cavitary, destroyed, pleural effusive and blood disseminative types. The principle preventive and therapeutic measures were also recommended. The authors concluded that all these would be helpful for early diagnosis, effective treatment, prognosis evaluation and scientific control of pneumoconiosis-tuberculosis.
