Abstract:
Objective To study the imaging distribution feature and diagnostic value of high resolution computed tomography(HRCT)in peripheral lung cancer(PLC).Methods The feature of imaging distribution was analysed in 37 patients with PLC by pathological proved,which compared with those in 23 cases with lung benign nodules by selected randomly.A double blind method was taken on the manifestations of HRCT about lung nodules tumor-lung interface in near heart side and far heart side.①cloudy or/and shaggy②spiculate③smooth.To search and define the correlation between its distributing feature;manifestations of 3 kinds HRCT;alteration of segment level bronchus and lung benign malignancy nodules.Results Cloudy,or shaggy,spiculalte departing from heart side in lung-tumor interface by HRCT were observed in peripheral lung cancer(79%) and benign nodules(22%);smooth was observed in peripheral lung cancer(14%) and benign nodules(74%).Some cases possed simultaneously two or more than two kinds HRCT's signs.Incidence rate of emphraxis and stenosis signs of segment level bronchus in PLC was higher than that in benign nodules.Conclusion Asymmetry apo-tip dominant position distribution of cloudy or shaggy,and spiculate change of tumor-lung interface by HRCT played an important role in qualitative diagnosis of peripheral lung cancer(≤3.5 cm).The appearance reason relates with the bronchial ventilation that the lesion results in occlusion.
