Abstract
전국 33개 진폐요양기관 흉부 방사선분야 정도관리 실태조사를 실시하여 정밀/요양기관(17개)과 요양기관(16개)에 대해 산업안전보건연구원 진폐정도관리 평가표를 이용하여 촬영기술, 판독환경 및 화질평가 결과를 비교 분석하였다. 촬영기술과 판독환경은 연구자가 직접방문하여 평가하였고, 화질평가는 각 진폐 요양기관에서 보내온 영상을 기관마다 10장씩 무작위추출하여 2명의 흉부 영상의학과 전문의가 영상에 대한 어떤 정보도 모르는 상태에서 개별적으로 실시하였다. 정밀/요양기관과 요양기관 사이, 흉부 방사선 촬영 장치의 성능, 사용기간, 촬영방법에서는 유의한 차이가 없었지만, 단순 흉부 촬영조건에서 관전압과 그리드 비에서 유의한 차이가 있었다. 또한, 촬영기술과 판독환경평가에서는 정밀/요양기관이 요양기관 보다 유의하게 높았고, 화질평가에서도 높았지만 유의한 차이는 없었다. 따라서, 진폐합병증이 있는 요양환자의 신뢰성있고 정확한 진단을 위해서는 요양기관의 흉부 방사선분야 정도관리 향상을 위한 외부평가 및 교육이 필요하다. To compare of quality control for chest radiography between special examination (SEP) and medical institution for pneumoconiosis (MIP). For the first time, we had visited at 33 institutions (SEP; 17 institutions, MIP; 16 institutions) to evaluate the quality control of chest radiography which is used in diagnosis of patients with pneumoconiotic complications. Image quality was rated by two experienced chest radiologists, and evaluated for radiological technique (RT), reading environment (RE) and image quality (IQ) between SEP and MIP according to the guideline published by OSHRI. Generator capacity, used duration and modality of chest radiography equipment were not signigicant difference between SEP and MIP, but there were signigicant difference in tube voltage and grid ratio used for chest radiography except to tube current and exposure time. SEP was statistically significant higher in RT (71.2 vs. 54.5, p=0.015), RE (78.8 vs. 51.5, p=0.007) to MIP, but not significant difference in IQ (64.8 vs. 59.3, p=0.180). For reliable and precisional diagnosis of patients with pneumoconiotic complications, the MIP requires the evaluation and education of quality control for improving chest radiography.
