The were followed until 31 December 2014, including true positives (TPs), negatives (TNs), false (FPs), (FNs), positive predictive values (PPVs), negative value (NPV), sensitivity specificity, confidence interval 95%.The showed high assurance, particularly regarding (90.22%) specificity (92.31%). overall (PPV) was 65.35%, (NPV) 98.32%. abnormal interpretation rate (recall rate) 12.26%.The are appropriate when compared proposed by edition. Additionally, provided self-reflection considering our radiological practice, which is essential improvements collaboration detection. It may stimulate better practice performance continuing education, despite possible infrastructure facility limitations.• Accurate rates financial governmental limitations. • Low-income institutions should develop standardised teamwork improve practice. Regular audits help increase health systems.
