Introduction: Mammography quality is directly related to the ability to detect an abnormality and, therefore, quality control is necessary for diagnostic imaging centers. Objective: To evaluate image quality, reading, and mammography service in some diagnostic imaging centers in Manizales, Colombia. Materials and methods: Four diagnostic imaging centers participated voluntarily in the study under confidentiality agreements. Out of 520 women attending the centers, 318 had a mammography. The infrastructure, technology, and human resources of each unit were evaluated based on visual inspections. A radiologist expert in reading and clinical interpretation of mammary images evaluated the quality of the image and the reading. We made the statistical analysis using anova, the kappa index, and the percentage of disagreement. Results: We found images of diminished quality mainly due to the presence of artifacts in 75 % of those evaluated, as well as non-compliance with identification criteria and image labeling. There were difficulties in taking the lateral median oblique projection given the absence of the inframammary. The level of agreement in the BI-RADS reporting was low in the four centers with important differences in the report and description of findings. Conclusion: The city’s diagnostic centers under evaluation are authorized for their operation. However, there are important deficiencies in image quality and reading, which highlights the need to seek quality standards starting from those aspects that can be improved upon.
乳腺摄影质量直接关系到发现异常的能力，因此，诊断成像中心需要进行质量控制。目的：评估哥伦比亚马拉开波市一些诊断成像中心的图像质量、读片和乳腺摄影服务。材料和方法：在保密协议的基础上，有 4 家诊断成像中心自愿参与了这项研究。在就诊的 520 名女性中，有 318 人进行了乳房 X 光检查。根据目视检查评估了每个单位的基础设施、技术和人力资源。一位擅长阅读和解读乳腺图像的放射科医生评估了图像质量和读片。我们使用方差分析、kappa 指数和不一致百分比进行了统计分析。结果：我们发现，由于 75%的评估图像存在伪影，以及不符合识别标准和图像标记，导致图像质量下降。由于缺乏乳房下皱褶，侧位中斜位拍摄存在困难。四个中心的 BI-RADS 报告一致性水平较低，报告和描述结果存在重要差异。结论：评估中所涉及的城市诊断中心获准运营。然而，在图像质量和读片方面存在重要缺陷，这突出表明需要从可以改进的方面寻求质量标准。
