Somewhat correct. If you test the software with a 1000 MRI scans from people with known diagnoses, the software will diagnose ~900 of them correctly. Roughly 97% sensitivity (3% false negative) and 85% specificity (15% false positive). False positive here is not real false positive, as the software is detecting abnormality in people who are still cognitively normal.
