TABLE 3.

Clinically relevant MR findings in ADNI 1–3.

Findings	Number of participants with various clinically relevant findings
Cerebral microbleed (CMB) – one or more CMB	641 (56%)
Infarction	361 (31%)
Superficial siderosis	57 (5%)
Developmental veinous anomaly	46 (4%)
Benign tumor	26 (2%)
Cavernous angioma	11 (1%)
Brain hemosiderin deposition	7 (1%)

Note: A total of 1149 individual findings appear in the table. The values in the table indicate the number of participants with different findings with the % of the total (1149) in parentheses. The number of infarctions is less than one might expect because cortical infarctions were exclusionary for the ADNI –3 cycles to mirror inclusion criteria for typical AD clinical trials. GRE images were not acquired in ADNI 1 and, therefore, CMB, superficial siderosis, developmental veinous anomaly (veinous angioma), cavernous angioma, and hemosiderin deposition numbers reflect only ADNI 2 and ADNI 3 counts.
