Abstract:
Objective To study the CT specialities of small lung cancer with the thin-section scan images by general CT machine.Methods Through the 3 mm-scan means in breathless condition,CT specialities of 36 cases of little lung carcinoma were analysed,which were scanned with CT before operation and proved by pathology.Results CT specialities of peripheral small lung cancer had lobular sign(91.6%);coarse spicules sign(77.8%);bubble-like lucency sign(50%);pleural retraction sign(88.9%);honeycomb sign(11.1%);cavity(2.7%);convergence sign of pulmonary vessels(66.7%),the radiative shadiness of pathological pleural side(11.1%).Conclusion The CT specialities are divided into prime and subaltern specialities in the diagnosis of peripheral small lung carinoma.The prime specialities have lobular sign,edge coarse spicules sign,bubble-like lucency sign,pleural retraction sign,convergence sign of pulmonary vessels,and the CT specialities are not agreeable with the small lung carcinoma of different tissue types.
