The Comparative Research Between High-kv X-ray Sternum And HRCT On 0,0～+,I Silicosis Small Shadow

ObjectiveIn our country, silicosis is the most serious vocational diseases that is harmful to workers. For a long time, we use high - kv X - ray sternum to diagnose silicosis in our country. As the HRCT widely used in clinic, high - kv X - ray sternum' s defect was gradually emerged. There are many errors in silicosis diagnosis, HRCT can notablely improve the display rate of the anatomic structure of lung,it arose people's recognition in silicosis diagnosis in domestic and overseas. This study through screen high - kv X - ray stemums and HRCT for 90 0, 0~+,Isilicosis patients and contrast their silicosis shadows, prove the virtue of HRCT in observing silicosis films.MethodsSelect 90 silicosis patients work in shengyang mine - machine factory, include 0 silicosis patients 30,0~+ silicosis patients 30,1 silicosis patients 30. then separate them to screen high - kv X - ray sternum and HRCT, contrast their silicosis shadow. Observe the small shadows' differens between high — kv X — ray sternum and HRCT. Use daojin800 mA ED 150 X - ray machine to screen sternum. Screen back - forward sternum by standing. Chest CT use GE Somatom plus machine. When being scan HRCT, patients are on their back,scan in the end of inspiration by hold their breath, from the top of lung to the bottom of lung, adopt high distinguish - bone rebuild arithmetic. Reading films by 5 members in shengyang silicosis diagnosis group. Adopt GBZ70 - 2002 silicosis diagnosis...
