Inclusion Criteria:
Mammograms included in the study should meet the following criteria:
- Female patients of 40 years of age or more.
- To have at least one screening mammography exam performed at Saint John's
- Cancer Institute during the study period. These exams will be included regardless of the brand of the mammography equipment.
- Mammograms should be performed with digital equipment.
Exclusion Criteria:
Mammograms with the following criteria will be excluded from the study:
- Patients with gigantomastia, defined by the need for more than one image of each mammographic view (mediolateral oblique and craniocaudal) to evaluate the entire breast volume.
- Patients with breast implants.
- Patients with a history of breast surgery.

Agreement between the majority report and Artemisia´s categorization of dense breasts/non-dense breasts
Zeitfenster: 2 months
|
The agreement between the CNN and the total of the professionals' categorizations will be calculated with the linear weighted kappa.
To this end, the categories assigned by the professionals will be considered as only one observer in each one of the studies and they will be compared to those assigned by Artemisia for the same set of images.

Agreement between the majority report and Artemisia in each one of the four breast density categories
Zeitfenster: 2 months
|
For each one of the professionals involved in the study, the agreement with the CNN will be calculated with the linear weighted kappa coefficient.
To this end, the categories assigned by the professionals will be considered as only one observer in each one of the studies and they will be compared to those assigned by Artemisia for the same set of images.
