Image quality, reading, and mammography service in four diagnostic imaging centers in Manizales, Colombia
Abstract
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.
