A total of 360 Head Computed Tomography exams were analyzed, using a checklist. For data collection, quality criteria were created, organized into four criteria groups, consisting of multiple items that must appear in the images studies. After data processing, a large number of non-conformexaminations were identified in than more than 50% of the sample. We concluded the main causes of these results are: the “incorrect or incomplete positioning”, the "lack of name of the radiographer and “motion artefacts”. Therefore it is essential to implement a checklist for a systematic evaluationof procedures.engImage qualityComputed tomographyConformitiesQuality control chartsjournal article10.5923/s.ajbe.201310.01
