A study on two different CAD systems for mammography as an aid to radiological diagnosis in the search of microcalcification clusters

In our study, not conditioned by the dataset, the CAD systems as second reader produced an increase in overall sensitivity of up to 15.7%, with a little decrease in specificity of up to 4.2%. Based on these results both CAD systems might be used in the current practise to improve the sensitivity values of conventional reading (radiologist alone). The results of this study show that no significant differences exist in term of Az, sensitivity and specificity between CALMA and CADx.
