Categories used to classify articles according to degree of influence on decision making
| Category | |
|---|---|
| 1 | Perfusion used to guide treatment |
| 2 | Predict clinical outcome (suggestive evidence that PWI can help triage patients) |
| 3 | Predict final infarct size |
| 4 | Determine effects of therapy on perfusion abnormalities |
| 5 | Characterize infarct types or to better understand infarct-like processes |
| 6 | As a comparison with DWI but no outcome measure |
| 7 | Compare perfusion with an imaging technique other than MR |
| 8 | Solely as an entry criterion |
| 9 | Although perfusion data were recorded, analysis of perfusion data was not a goal of the study |
Note:—PWI indicates perfusion-weighted imaging; DWI, diffusion-weighted imaging.
