高千伏X线胸片是我国GBZ 70—2015《职业性尘肺病的诊断》强制采用的尘肺病诊断、分期工具,常常需要联合应用计算机体层成像(CT)进行鉴别诊断,但胸部CT检查尘肺病缺乏规范性的技术指导.为此,中国卫生监督协会团体标准委员会批准了中国疾病预防控制中心职业卫生与中毒控制所关于《CT用于尘肺病辅助检查指南》的立项申请.在中华预防医学会职业病分会尘肺病影像学组的指导下,项目组撰写了本共识.其中:鉴于尘肺病检查的特殊性,对CT机和附属设备的配置制定了具体要求;为了获得高质量图像,对扫描前的准备、图像层厚等扫描和图像重建参数组合制定了具体要求;基于CT是数字图像的基础,对图像后处理方法提出了具体要求;为了获得规范的大数据,对图像数据的存储也做了相应要求;为了方便使用,制定了CT图像质量评价方法.“,”High kV chest X-ray radiographs are a compulsory tool for the diagnosis and staging of pneumoconiosis stipulated by the Diagnosis of occupational pneumoconiosis (GBZ 70-2015) in China, and often combine with computed tomography (CT) examination for further differential diagnosis. However, chest CT examination for pneumoconiosis requires standardized technical guidance. Thus, the Group Standards Committee of the China Health Inspection Association approved the application of the Institute of Occupational Health and Poison Control of the Chinese Center for Disease Control and Prevention to develop a guideline for chest CT assisting examinations of pneumoconiosis patients. Under the direction of the Pneumoconiosis Imaging Group of Occupational Disease Branch of Chinese Preventive Medicine Association, the “Consensus of experts on the technical specification of chest CT examination of pneumoconiosis (2020 edition)” was drafted. Given the particularity of pneumoconiosis examination, the configurations of CT machines and auxiliary equipment were specified. To obtain high-quality images, specific requirements were made for the scanning and image reconstruction parameters such as preparation before scanning and image slice thickness. Based on the fact that CT outputs digitized images, image post-processing methods were addressed. To achieve standardized big data, the archiving of image data was detailed. For convenient application, the evaluation method of CT image quality was established.
