Design outcomes

Primary

Measure	Time frame
Primary outcome is the vessel visibility rating, assessed by three neuroradiologist using a 3-point scale. Different MRA sequences shall be compared with PETRA. Source data are the MR images acquired from the clinically indicated Follow-Up imaging.	—

Secondary

Measure	Time frame
Image quality Recurrence or Reperfusion Comparison to other modalities Influence of type of device Limits of PETRA in visualizing peripheral intracranial vessels.	—
