目的探讨不同尘肺病高千伏(HKV)胸片X线形态学特征,为修订尘肺病诊断标准提供依据。方法采用回顾性调查方法,按照最新尘肺病诊断标准,对3 689例尘肺病胸片X线形态学进行分析,并将结果建立数据库,用SPSS 17.0软件进行统计分析。结果基于3 689例尘肺病X线形态学改变结果分析,圆形小阴影表现为:p影508例(13.8%),q影1 501例(40.7%),r影279例(7.6%);不规则小阴影表现为:s影246例(6.7%),t影1 414例(38.3%);大阴影280例(7.6%),小阴影聚集196例(5.3%)。小阴影肺区分布主要在两肺中下肺区;各种尘肺病同时伴有肺纹理(60.3%)、肺门(35.5%)、胸膜(11.4%)、肺气肿(16.7%)等X线异常征象。结论 HKV胸片大阴影、小阴影形态、分布以及小阴影密集度的判定等,在尘肺病诊断分期中至关重要,分析发现,胸膜、肺门、肺纹理、肺气肿、肺结核等X射线影像学特征,与尘肺诊断密切相关,具有重要参考价值。
Objective To investigate the X-ray morphological characteristics of high kV (kV) chest radiograph in different pneumoconiosis patients and provide the basis for revising the diagnostic criteria of pneumoconiosis. Methods The retrospective investigation method was used to analyze the X-ray morphology of 3 689 patients with pneumoconiosis according to the latest diagnostic criteria of pneumoconiosis. The database was constructed and the results were analyzed by SPSS 17.0 software. Results Based on the analysis of X-ray findings of 3 689 cases of pneumoconiosis, the results of circular small shadows were: 508 cases (13.8%) in p-ray, 501 cases (40.7%) in q-ray and 279 cases (7.6% Irregular small shadows were as follows: 246 cases (6.7%) of s were affected, 414 cases (38.3%) of which were absent, 280 cases (7.6%) were large shadows, and 196 cases (5.3%) were small shadows. Small shadow lung area distribution mainly in the lungs in the lower lung area; a variety of pneumoconiosis accompanied by lung texture (60.3%), hilar (35.5%), pleura (11.4%), emphysema (16.7%) and other X Abnormal signs of line. Conclusions The determination of large shadow, small shadow shape, distribution and small shadow density of HKV chest radiographs is very important in the staging of pneumoconiosis. It is found that pleura, hilar, lung texture, emphysema, tuberculosis and other X-ray Imaging features, closely related with the diagnosis of pneumoconiosis, has important reference value.
