+/+: left breast + and right breast +; +/−: left breast + and right breast −; −/+: left breast − and right breast +; −/−: left breast − and right breast −. NA: not applied (no histopathology examination). A positive test represents at least one side breast showing +. A negative test represents both sides showing −. Participants without 3D-PEM were considered to show inconsistent results compared with WBPET.
