[Abstract] Objective Tries to analyze the application of radiological technology， and the factors influencing the imaging quality. Methods In 2016， there were 10 749 general X-ray examinations， 7 650 CR and DR examinations， 895 CT examinations， 305 MRI examinations and 250 DSA examinations. At the same time， 10 radiologists were surveyed to evaluate the influencing factors on the quality of radiology imaging technology from January to December 2016 in the hospital. Results From the examination of the image quality， the lowest pass rate of X-ray examination was 97.46%， the incidence of adverse events CT highest of 1.23%， MRI， DSA examination satisfaction rates were 92.13%， 92.80%， CT department satisfaction rate of the lowest 91.06%. The operators experience and technical level of the highest score of 40 points， followed by the purpose of inspection and imaging ease of 37 points， once again for the performance of equipment and state 36 points， equipment parameters and mode setting 35 points， patients cooperative ability 33 points， 32 points for the type of technique， and 25 points for the pre-examination preparation quality. Conclusion It is necessary to improve the application quality of radiological techniques and to improve the technical level of operation.

放射科是利用X線机、计算机X线摄影系统（CR）、数字化X线机（DR）、计算机X线断层扫描（CT）、核磁共振（MRI）、数字减影血管造影系统（DSA）等设备开展检查、诊断、治疗的科室，已被广泛应用于冠心病等血管性疾病、脑卒中等颅内病变、甲状腺肿瘤等肿瘤性疾病等诊断之中[1]。但放射诊断技术并非万能灵药，除“DSA”外，其他诊断技术都不能作为“金标准”，也存在误漏诊。同时在具体应用过程中，部分患者可能不能接收检查，检查还可能引起放射性损害，部分检查需要进行灌注扫描，会出现血管穿刺损伤，造影剂可能引起过敏，DSA甚至可能引起心血管事件。该次研究……
