Aims and objectives: The aim of this study was to assess if the image quality from head CT examinations meets the quality criteria previously established in a radiology department. The specific objectives were to identify the presence of conformities and nonconformities in the head CT images, to understand the causes of[...]

Methods and materials: A retrospective study was conducted in a public radiology department using a random sample of 360 head CT examinations grouped in 12 smaller samples, each one with 30 exams. Using a quality criteria checklist organized into four main groups (table 1), the conformities and non-conformities found were[...]

Results: The p Control Chart (fig.1) illustrates the percentage of noncompliant head CT studies and the following values were obtained for the central limit (CL), upper limit control (ULC) and lower limit control (LLC): 60.83%, 87 57% and 34.09%. It was found that there were no statistical control samples ou[...]

Conclusion: The existence of suitable quality control of the image is essential to achieve high quality standards. Strategies for improving radiographers performance must be implemented to ensure that head CT examinations are performed in compliance with all the quality criteria established. Therefore, it is es[...]
