Abstract

The auther studied the relationship between patho-anatomical structure and radiological findings in one hundred cases of primary carcinoma of the lung, and should like to conclude as follows : 1) Radiologically, primary lung cancer can be classified in 3 major groups as follows : a) nodular type, b) infiltrative type, c) secondary changes. The nodular type is most frequently found of three types. 2) Nodular shadows are frequently accompained by linear shadow, radiated shadow or triangular shadow. 3) Accompanying shadows are suggestive on site and extension of original lesions of lung cancer. 4) Retrospective observations of X-ray films show that many cases of lung cancer arise peripherally and appear as the infiltrative type in the earliest stage. 5) The rate of growth of the lung cancer was estimated roentgenologically by the method of Collins and others. The volume doubling time ranged from 2 months to 6 months.
