Abstract:
Objective （ ）
To explore the application value of bone suppression imaging BSI in the diagnosis of occupational
（ pneumoconiosis） Methods -
pneumoconiosis hereinafter referred to as " " . A total of 330 chest films of high kV digital
（ ）
radiograph DR of patients with suspected pneumoconiosis were selected by convenient sampling method. BSI is applied to the
， ， ， ，
chest films and the differences of small opacity shape small opacity aggregation the number of large opacity lung areas small
（ ），
opacity profusion and diagnostic stage of pneumoconiosis were analyzed by simple DR reading DR group simple BSI reading
（ ） （ ） Results
BSI group and DR and BSI combined reading combined group . There was no significant difference in the
distribution of small shadows and the detection rate of small shadows aggregation and large shadows in pneumoconiosis among
（ P ） ，
the three film reading methods all >0.05 . For the concentration distribution of each lung area there was statistically
（P< ），
significant difference between the DR group and the BSI group 0.05 but there was no statistically significant difference
， （ P ）
between the DR group and the combined group and between the BSI group and the combined group all >0.05 . The results of
，
consistency analysis showed that the DR group and the BSI group and the DR group and the combined group had high
（ ， P<
consistency in the judgment of small shadow intensity in the lung region both weighted Kappa coefficient were 0.75 all
）
0.01 . There was a high consistency between BSI group and DR group and combined group and DR group in the diagnosis of
（ ， ， P< ） ，
pneumoconiosis stage weighted Kappa coefficient were 0.77 0.79 all 0.01 . Compared with the DR group the diagnostic
，
rate of pneumoconiosis stage Ⅰwas significantly reduced and the diagnostic rate of pneumoconiosis stage Ⅱ was significantly
（ P< ） ，
increased in the BSI group and the combined group all 0.01 . However there was no significant difference in the diagnosticrate of pneumoconiosis stage Ⅲ >0.05 . Both the BSI reading and DR and BSI combined reading can improve
，
the display of pneumoconiosis lesions to varying degrees and therefore can improve the diagnosis of pneumoconiosis. In
，
addition the identification and diagnosis of pneumoconiosis lesions in the BSI reading is comparable to that in the combined
，
group which has a good application value in the diagnosis of pneumoconiosis.
