Resumo(s)
Themain objective of this research was to determine if the diagnostic image, acquired by CT scan, meets the
quality criteria previously established for head CT exams. 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.
