影响乳腺X线导管造影图像质量的因素分析及处理对策

Analysis of factors affecting the image quality of breast X-ray catheterization and its processing countermeasures

目的对影响乳腺X线导管造影图像质量的因素进行调查收集,总结常发生的问题并提出处理对策,为临床提供能满足诊治要求的导管造影图像。方法回顾性收集2016年1月—2019年12月我院行乳腺X线导管造影检查的资料,检查成功的共有2850例,其中一次性成功者2609例,进行二次检查的导管造影的病例241例,对比两次造影检查的过程与图像质量。结果影响导管造影图像质量或造成造影术失败的常见原因有8大类,导管内容物干扰导管的显示最多,有70例;导管内空气造成的伪影有43例;注入对比剂过多有36例;注入对比剂过少有29例;拍片时压力过大有25例;呼吸运动伪影有20例;对比剂误入其他导管有14例;其他原因有4例。针对不同的原因与高年资技师、诊断医师分析并找出应对方法,获得满足临床诊治的图像。结论乳腺X线导管造影的图像质量好坏,影响临床对导管内有无病变的诊断,耽误患者病情的治疗,技师应针对不同的情况采取相适宜的应对方法,可以有效解决造影失败问题,提升乳腺导管造影成功率,提高导管造影图像质量,满足临床诊治所需。

Objective To investigate and collect the factors that affect the quality of mammography images,summarize the common problems and propose countermeasures,so as to provide the angiographic images that can meet the clinical requirements of diagnosis and treatment.Methods The mammography from January 2016 to December 2019 was retrospectively collected.A total of 2850 cases were successfully examined,of which 2609 cases were successful at one time and 241 cases were subject to secondary examination.The process and image quality of the two examinations were compared.Results The images of 241 cases with 2 times of mammography were compared and analyzed,the factors affecting the image quality of the previous mammography were analyzed,and the countermeasures for the successful treatment of the latter mammography were summarized.There are 8 kinds of common reasons that affect the image quality of catheter angiography or cause the failure of angiography.The content of catheter interferes with the display of catheter most,with 70 cases;there were 43 cases of artifacts caused by air in the catheter;36 cases were injected too much contrast agent;29 cases were injected with too little contrast agent;there were 25 cases with excessive pressure during filming;20 cases of respiratory motion artifact;there were 14 cases of contrast agent mistakenly entering other catheter;there were 4 other reasons.When operating,analyze the different reasons with senior technicians and diagnostic doctors,find out the response methods,and summarize and share the methods to meet the clinical diagnosis and treatment image.Conclusion The image quality of mammography affects the clinical diagnosis of lesions in the duct and delays the treatment of the patient′s condition.Technicians should take appropriate countermeasures according to different situations,which can effectively solve the problem of mammography failure,improve the success rate of mammography,improve the image quality of mammography,and meet the needs of clinical diagnosis and treatment.
