The image report or image performance conforms to any of the following: (1) Report intracranial hemorrhage and imaging report indicates acute/hyperacute phase, or the traceable onset time is less than 72 hours; (2) No intracranial hemorrhage was reported; (3) Imaging and related clinical information are complete and can be traced.
Exclusion criteria
