Inclusion criteria

Inclusion criteria: Patients who have received neuroradiological imaging since 01.01.2000 on suspicion of a stroke in whom ischemic stroke or transient ischemic attack has been confirmed.

Exclusion criteria

Exclusion criteria: A specific patient exclusion is not planned to prevent the algorithms for patient subgroups from being falsified.

Design outcomes

Secondary

Measure	Time frame
Descriptive statistics of the derived imaging parameters (infarct volumes, cerebral blood flow, cerebral blood volume etc.) and comparison with a possibly existing follow-up imaging taking into account the therapy performed.	—

Primary

Measure	Time frame
